Fibroblast behavior underlies a spectrum of clinical entities, but they remain poorly characterized, largely due to their inherent heterogeneity. Traditional fibroblast research relies upon in vitro manipulation, masking in vivo fibroblast behavior. We describe a FACS-based protocol for the isolation of mouse skin fibroblasts that does not require cell culture.

Generating Neurons by Reprogramming Human Dermal Fibroblast Cells

The video demonstrates the generation of neurons from adult human dermal fibroblasts (aHDFs). The aHDFs are reprogrammed using a lentiviral vector carrying genes for neuronal transcription factors and short hairpin RNAs (shRNAs). The shRNAs inhibit the expression of a neuronal transcriptional repressor, and the neuronal transcription factors activate genes to differentiate aHDFs into neurons. These reprogrammed aHDFs are cultured in an early and a late neuronal conversion medium to generate...

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.
FAQs
Enzymatic digestion loosens the extracellular matrix that holds dermal cells within connective tissue. This reduces the physical association between cells and their surrounding matrix, allowing individual cells or small cell groups to be released from minced tissue. The resulting suspension can then undergo filtration or centrifugation, making the cells accessible for controlled culture and experimental analysis.
Mincing breaks the dermis into smaller tissue fragments before enzymatic treatment. This preparation exposes more tissue to the digestion process and helps the enzyme act throughout the sample rather than only at its outer surface. As a result, released cells can be collected more effectively for subsequent separation and maintenance in culture.
Filtration and centrifugation provide complementary separation steps after enzymatic digestion. Filtration helps remove remaining tissue fragments from the released-cell suspension, while centrifugation separates the cells from the surrounding digestion mixture. Together, these operations produce a cleaner cell preparation suitable for maintaining dermal cells under controlled culture conditions.
Fibroblast-rich populations are valuable because fibroblasts contribute to extracellular-matrix production within the dermis. Studying these cells therefore supports investigations of skin structure and the cellular processes involved in wound healing. Their availability in isolated preparations also provides a practical basis for examining how dermal cells respond in culture or within tissue-engineering studies.
A typical workflow begins by mincing dermal tissue, followed by enzymatic digestion to loosen its extracellular matrix. The released material is then processed through filtration or centrifugation to separate cells from undigested components. Finally, the isolated cells are maintained in culture conditions, where researchers can study their behavior under controlled experimental settings.
Isolated dermal cells are used in tissue-engineering research when investigators need to examine cellular interactions with engineered materials or tissue environments. The cells can support studies of skin structure, extracellular-matrix production, and wound healing. They also allow researchers to evaluate how dermal populations respond to biomaterials or growth factors in controlled culture systems.
The technique provides cells from the dermis for controlled investigation of disease-related or treatment-related responses. Cultured dermal cells can be used to study skin disorders and to test how cells react to growth factors, biomaterials, or other experimental treatments. These observations help connect cellular behavior with broader questions about skin repair and tissue function.
