Bu yazıda tarif edilen protokol, bir alt seçmek ya da daha sonraki analizler yapılmadan önce, hücre kültüründe bir zaman gerektiren ya mevcut yöntemlere kıyasla, FACS-bazlı sıralama ile fibroblastlar izole etmek için bir araç sunmaktadır. Fibroblast sıralama için cildin hasat gerekli süre yaklaşık 6 saattir; Bununla birlikte, hasat kullanılan farelerin sayısı, bu tahmin etkileyecektir. Protokolde birkaç nokta özellikle dikkat gerektirir. İlk izolasyon prosesi esnas?...

Fibroblastlar sık ​​plastik yüzeylerde uygun iğ biçimli hücreler olarak morfolojik tanımlanır. Fibroblastlar sentezlenmesi ve embriyonik ve yetişkin organlarının 1 hücre dışı matriks remodeling sorumlu ilke hücre tipi vardır. Fibroblastlar memeli gelişme dolayısıyla kritik ve her doku ve organda mevcut hücre tipleri komşu davranışını etkileyen hücre dışı ortamın önemli ölçüde katkıda bulunur. Fibroblastlar de muazzam bir klinik yükünü neden tıbbi koşullar çeşitli bir kümesi arkasında asıl hücre tipi vardır. Patolojik fibroblast aktivitesinin normal doku işlevini bozar ve deri yara iyileşmesi, ateroskleroz, sistemik skleroz, ve damar yaralanması 2-5 sonra aterom plaklarının oluşumuna aşağıdaki doku ve (örneğin akciğer ve karaciğer gibi), organ fibrozis, skar içerir. Özellikle yara iyileşmesi, hem akut ve kronik, d içerirnormal doku gibi ne benzeyen, ne de işlevleri çevreleyen ve çeşitli patolojik devletler arasında önemli morbidite neden skar dokusunun eposition. Travmalarından sonra, daha sonra, yapısal ECM bileşenleri salgılar hücre tiplerini komşu parakrin etkilere neden ve skar dokusu 6 yatırma mekanik istikrarı sağlamak miyofibroblastlar fibroblastların bir geçiş vardır. Deri dokularda gelişimsel süre boyunca yara onarım kalitesi ve anatomik siteler arasında önemli varyasyon mevcuttur. Yaşamın ilk iki trimesterde fetüs iz bırakmadan iyileşir; Ancak, üzerinde ve yetişkinlik boyunca üçüncü trimesterde, bir yara ile iyileşir insanlarda. Mevkiye-özgü yaşa özgü ek olarak, yara iyileşmesi farklılıklar vardır. Deri yaraların içinde skar dokusu biriktirme 9 önemli ise ağız boşluğunda yaralar, minimal skar oluşumu 7,8 ile pişmanlık. Münakaşa c devamyaş ve konum 10,11 hem açısından yara iyileşmesi sonucu yerel fibroblast içsel özelliklerinin karşı çevrenin göreceli etkisini oncerning. Deri dermis ve önceki embriyonik (E15) karşı sözlü fare iyileşmesinde önemli farklılıklar göz önüne alındığında vs sonra embriyonik (E18) dermiş, bazı gelişimsel yaşta ve çeşitli anatomik siteler arasında fibroblastların popülasyonlarında içsel farklılıklar var olasıdır . 1986 yılında, Harold F. Dvorak tümörler 12 iyileşmeyen yaralar vardır oturtulması. Dvorak tümörler vücutta yaralar gibi davranırlar ve konağın yanıtını yaranın iyileşme aktive ederek stroma neden olduğu sonucuna varıldı. Çeşitli çalışmalar beri karsinom 13-15 ilerlemesine fibroblastların katkısını araştırdık, ama yara iyileşmesi, kimlik ve deri ca stromal bölmesine katkıda fibroblast embriyonik kökenli olduğu gibircinomas yeterince tanımlanmamıştır. Bu sorunun cevabı, anti-kanser terapisi 16 için potansiyel olarak etkin hedef olarak tümörle ilişkili fibroblast açığa son çalışmalar verilen tıbbi alaka taşımaktadır. Belirlenmesi ve ileriye dönük in vivo fibrojenik potansiyeli sahip fibroblast soy izole etkin bir akut ve kronik hastalık durumları geniş bir yelpazesinde yaralanma kendi tepkisini manipüle yönelik önemli bir adımdır. 1987 yılında, Cormack papiller ve retiküler dermis 17,18 içinde biri içinde ikamet eden fibroblast iki alt popülasyonlarını bir gösterdi. Üçüncü ICSI&#39;nin follikül 19,20 Dermal papilla bölgedeki saç köklerinin ile ilişkili bulunmuştur. Ne zaman kültür, büyüme potansiyeli, morfoloji ve büyüme faktörü / sitokin bu fibroblast alt tiplerinin sergi farkları 21-24 profilleri. Bugüne kadar, fibroblast inceleyen çalışmaların oterogeneity ölçüde yeterli in vivo fibroblastlar arasında gelişimsel ve fonksiyonel çeşitlilik karakterize etmek başarısız oldu. Bu, kısmen, kültürlenmiş fibroblast popülasyonları bir güven ve tüm fibroblastlar 25 ile ifade edilen bir kendi kendine yüzey reseptörüne göre hücre kültüründen ya da pozitif bir seçim homojenize etkisinin bir sonucu olduğu. Laboratuarımızda yapılan yeni bir çalışma, derin bir yüzey işaretleyici ve bu yazıda 26 sunulan FACS-bazlı izolasyon metodolojisi ile izole vs kültürlü kültürsüz fibroblast transkripsiyonel vardiya gösterdi. Daha sonra, kemirgen dorsal dermiş içinde belirli bir fibroblast soy tanımlanmış ve Engrailed-1 embriyonik ekspresyonu ile tanımlanan, bu soy, dorsal, derideki bağ dokusu birikimi için temel olarak sorumlu olduğu tespit edilmiştir. Yara iyileşmesi, kanser stroma oluşumu da dahil olmak üzere fibrozis, akut ve kronik biçimleri boyunca da soy fonksiyonlarıRadyasyon fibrozis 27 uyarılan.

Isolating Hair Follicle Stem Cells and Epidermal Keratinocytes from Dorsal Mouse Skin

The hair follicle (HF) is an ideal system for studying the biology and regulation of adult stem cells (SCs). This dynamic mini organ is replenished by distinct pools of SCs, which are located in the permanent portion of the HF, a region known as the bulge. These multipotent bulge SCs were initially identified as slow cycling label retaining cells; however, their isolation has been made feasible after identification of specific cell markers, such as CD34 and keratin 15 (K15). Here, we describe a robust method for isolating bulge SCs and epidermal keratinocytes from mouse HFs utilizing fluorescence activated cell-sorting (FACS) technology. Isolated hair follicle SCs (HFSCs) can be utilized in various in vivo grafting models and are a valuable in vitro model for studying the mechanisms that govern multipotency, quiescence and activation.

An ideal model for studying adult stem cell biology is the mouse hair follicle. Here we present a protocol for isolating different populations of hair follicles stem cells and epidermal keratinocytes, employing enzymatic digestion of mouse dorsal skin followed by FACS analysis.

Rapid Generation of Primary Murine Melanocyte and Fibroblast Cultures

Defects in fibroblast or melanocyte function are associated with skin diseases, including poor barrier function, defective wound healing, pigmentation defects and cancer. Vital to the understanding and amelioration of these diseases are experiments in primary fibroblast and melanocyte cultures. Nevertheless, current protocols for melanocyte isolation require that the epidermal and dermal layers of the skin are trypsinized and manually disassociated. This process is time consuming, technically challenging and contributes to inconsistent yields. Furthermore, methods to simultaneously generate pure fibroblast cultures from the same tissue sample are not readily available. Here, we describe an improved protocol for isolating melanocytes and fibroblasts from the skin of mice on postnatal days 0-4. In this protocol, whole skin is mechanically homogenized using a tissue chopper and then briefly digested with collagenase and trypsin. Cell populations are then isolated through selective plating followed by G418 treatment. This procedure results in consistent melanocyte and fibroblast yields from a single mouse in less than 90 min. This protocol is also easily scalable, allowing researchers to process large cohorts of animals without a significant increase in hands-on time. We show through flow cytometric assessments that cultures established using this protocol are highly enriched for melanocytes or fibroblasts.

This protocol outlines a rapid method to simultaneously generate melanocyte and fibroblast cultures from the skin of 0-4 day old mice. These primary cultures can be maintained and manipulated in vitro to study a variety of physiologically relevant processes, including skin cell biology, pigmentation, wound healing and melanoma.

Isolation of Papillary and Reticular Fibroblasts from Human Skin by Fluorescence-activated Cell Sorting

Fibroblasts are a highly heterogeneous cell population implicated in the pathogenesis of many human diseases. In human skin dermis, fibroblasts have traditionally been attributed to the superficial papillary or lower reticular dermis according to their histological localization. In mouse dermis, papillary and reticular fibroblasts originate from two different lineages with diverging functions regarding physiological and pathological processes and a distinct cell surface marker expression profile by which they can be distinguished.
Importantly, evidence from explant cultures from superficial and lower dermal layers suggest that at least two functionally distinct dermal fibroblasts lineages exist in human skin dermis as well. However, unlike for mouse skin, cell surface markers enabling the discrimination of different fibroblast subsets have not yet been established for human skin. We developed a novel protocol for the isolation of human papillary and reticular fibroblast populations via fluorescence-activated cell sorting (FACS) using the two cell surface markers Fibroblast Activation Protein (FAP) and Thymocyte antigen 1 (Thy1)/CD90. This method enables the isolation of pure fibroblast subsets without in vitro manipulation, which was shown to affect gene expression, thus permitting accurate functional analysis of human dermal fibroblast subsets in regard to tissue homeostasis or disease pathology.

This manuscript describes a FACS-based protocol for isolation of papillary and reticular fibroblasts from human skin. It circumvents in vitro culture which was inevitable with the commonly used isolation protocol via explant cultures. The emanating fibroblast subsets are functionally distinct and display differential gene expression and localization within the dermis.

Isolation of Adult Human Dermal Fibroblasts from Abdominal Skin and Generation of Induced Pluripotent Stem Cells Using a Non-Integrating Method

Induced pluripotent stem cells (iPSCs) could be considered, to date, a promising source of pluripotent cells for the management of currently untreatable diseases, for the reconstitution and regeneration of injured tissues and for the development of new drugs. Despite all the advantages related to the use of iPSCs, such as the low risk of rejection, the lessened ethical issues, and the possibility to obtain them from both young and old patients without any difference in their reprogramming potential, problems to overcome are still numerous. In fact, cell reprogramming conducted with viral and integrating viruses can cause infections and the introduction of required genes can induce a genomic instability of the recipient cell, impairing their use in clinic. In particular, there are many concerns about the use of c-Myc gene, well-known from several studies for its mutation-inducing activity. Fibroblasts have emerged as the suitable cell population for cellular reprogramming as they are easy to isolate and culture and are harvested by a minimally invasive skin punch biopsy. The protocol described here provides a detailed step-by-step description of the whole procedure, from sample processing to obtain cell cultures, choice of reagents and supplies, cleaning and preparation, to cell reprogramming by the means of a commercial non-modified RNAs (NM-RNAs)-based reprogramming kit. The chosen reprogramming kit allows an effective reprogramming of human dermal fibroblast to iPSCs and small colonies can be seen as early as 24 h after the first transfection, even with modifications with the respect to the standard datasheet. The reprogramming procedure used in this protocol offers the advantage of a safe reprogramming, without the risk of infections caused by viral vector-based methods, reduces the cellular defense mechanisms, and allows the generation of xeno-free iPSCs, all critical features that are mandatory for further clinical applications.

Cell reprogramming requires the introduction of key genes, which regulate and maintain the pluripotent cell state. The protocol described enables the formation of induced pluripotent stem cells (iPSCs) colonies from human dermal fibroblasts without viral/integrating methods but using non-modified RNAs (NM-RNAs) combined with immune evasion factors reducing cellular defense mechanisms.

Isolation of Normal and Cancer-associated Fibroblasts from Fresh Tissues by Fluorescence Activated Cell Sorting (FACS)

Cancer-associated fibroblasts (CAFs) are the most prominent cell type within the tumor stroma of many cancers, in particular breast carcinoma, and their prominent presence is often associated with poor prognosis1,2. CAFs are an activated subpopulation of stromal fibroblasts, many of which express the myofibroblast marker &alpha;-SMA3. CAFs originate from local tissue fibroblasts as well as from bone marrow-derived cells recruited into the developing tumor and adopt a CAF phenotype under the influence of the tumor microenvironment4. CAFs were shown to facilitate tumor initiation, growth and progression through signaling that promotes tumor cell proliferation, angiogenesis, and invasion5-8. We demonstrated that CAFs enhance tumor growth by mediating tumor-promoting inflammation, starting at the earliest pre-neoplastic stages9. Despite increasing evidence of the key role CAFs play in facilitating tumor growth, studying CAFs has been an on-going challenge due to the lack of CAF-specific markers and the vast heterogeneity of these cells, with many subtypes co-existing in the tumor microenvironment10. Moreover, studying fibroblasts in vitro is hindered by the fact that their gene expression profile is often altered in tissue culture11,12 . To address this problem and to allow unbiased gene expression profiling of fibroblasts from fresh mouse and human tissues, we developed a method based on previous protocols for Fluorescence-Activated Cell Sorting (FACS)13,14. Our approach relies on utilizing PDGFR&alpha; as a surface marker to isolate fibroblasts from fresh mouse and human tissue. PDGFR&alpha; is abundantly expressed by both normal fibroblasts and CAFs9,15 . This method allows isolation of pure populations of normal fibroblasts and CAFs, including, but not restricted to &alpha;-SMA+ activated myofibroblasts. Isolated fibroblasts can then be used for characterization and comparison of the evolution of gene expression that occurs in CAFs during tumorigenesis. Indeed, we and others reported expression profiling of fibroblasts isolated by cell sorting16. This protocol was successfully performed to isolate and profile highly enriched populations of fibroblasts from skin, mammary, pancreas and lung tissues. Moreover, our method also allows culturing of sorted cells, in order to perform functional experiments and to avoid contamination by tumor cells, which is often a big obstacle when trying to culture CAFs.

Ultrasonic-augmented Primary Adult Fibroblast Isolation

Primary adult fibroblasts have become an important tool to study fibrosis, fibroblast interactions and inflammation in all body tissues. Since primary fibroblasts cannot divide indefinitely due to myofibroblast differentiation or senescence induction, new cultures must be established regularly. However, there are several obstacles to overcome during the processes of developing a reliable isolation protocol and primary fibroblast isolation itself: the method&#8217;s degree of difficulty (especially for beginners), the risk of bacterial contamination, the required time until primary fibroblasts can be used for experiments, and subsequent cell quality and viability. In this study, a fast, reliable and easy-to-learn protocol to isolate and culture primary adult fibroblasts from mouse heart, lung, liver and kidney combining enzymatic digestion and ultrasonic agitation is provided.

We present a protocol to isolate primary adult fibroblasts in an easy, fast and reliable way, performable by beginners (e.g., students). The procedure combines enzymatic tissue digestion and mechanical agitation with ultrasonic waves to obtain primary fibroblasts. The protocol can easily be adapted to specific experimental requirements (e.g., human tissue).

Isolation, Culture, and Characterization of Primary Dermal Fibroblasts from Human Keloid Tissue

Fibroblasts, the major cell type in keloid tissue, play an essential role in the formation and development&#160;of keloids. The isolation and culture of primary fibroblasts derived from keloid tissue are the basis for further studies of the biological function and molecular mechanisms of keloids, as well as new therapeutic strategies for treating them. The traditional method of obtaining primary fibroblasts has limitations, such as poor cellular state, mixing with other types of cells, and susceptibility to contamination. This paper describes an optimized and easily reproducible protocol that could reduce the occurrence of possible issues when obtaining fibroblasts. In this protocol, fibroblasts can be observed 5 days after isolation and reach nearly 80% confluency after 10 days of culture. Then, the fibroblasts are passaged and verified using PDGFR&#945; and vimentin antibodies for immunofluorescence assays and CD90 antibodies for flow cytometry. In conclusion, fibroblasts from keloid tissue can be easily acquired through this protocol, which can provide an abundant and stable source of cells in the laboratory for keloid research.

This study describes an optimized protocol for establishing primary fibroblasts from keloid tissues that can effectively and steadily provide pure and viable fibroblasts.

Isolation and Characterization of Adult Cardiac Fibroblasts and Myofibroblasts

Cardiac fibrosis in response to injury is a physiological response to wound healing. Efforts have been made to study and target fibroblast subtypes that mitigate fibrosis. However, fibroblast research has been hindered due to the lack of universally acceptable fibroblast markers to identify quiescent as well as activated fibroblasts. Fibroblasts are a heterogenous cell population, making them difficult to isolate and characterize. The presented protocol describes three different methods to enrich fibroblasts and myofibroblasts from uninjured and injured mouse hearts. Using a standard and reliable protocol to isolate fibroblasts will enable the study of their roles in homeostasis as well as fibrosis modulation.

Obtaining a pure population of fibroblasts is crucial to studying their role in wound repair and fibrosis. Described here is a detailed method to isolate fibroblasts and myofibroblasts from uninjured and injured mouse hearts followed by characterization of their purity and functionality by immunofluorescence, RTPCR, fluorescence-assisted cell sorting, and collagen gel contraction.

Murine Dermal Lymphatic Endothelial Cell Isolation

The lymphatic system participates in the regulation of immune surveillance, lipid absorption, and tissue fluid balance. The isolation of murine lymphatic endothelial cells is an important process for lymphatic research, as it allows the performance of in vitro and biochemical experiments on the isolated cells. Moreover, the development of Cre-lox technology has enabled the tissue-specific deficiency of genes that cannot be globally targeted, leading to the precise determination of their role in the studied tissues. The dissection of the role of certain genes in lymphatic physiology and pathophysiology requires the use of lymphatic-specific promoters, and thus, the experimental verification of the expression levels of the targeted genes.
Methods for efficient isolation of lymphatic endothelial cells from wild-type or transgenic mice enable the use of ex vivo and in vitro assays to study the mechanisms regulating the lymphatic functions and the identification of the expression levels of the studied proteins. We have developed, standardized and present a protocol for the efficient isolation of murine dermal lymphatic endothelial cells (DLECs) via magnetic bead purification based on LYVE-1 expression. The protocol outlined aims to equip researchers with a tool to further understand and elucidate important players of lymphatic endothelial cell functions, especially in facilities where fluorescence-activated cell sorting equipment is not available.
