This video describes the isolation of keratinocytes—the most prominent cells of human skin's epidermal layer, by employing a combination of enzymatic digestion and mechanical disruption methods. This method helps in the preferential growth of keratinocytes over other skin cell types using a selective growth medium.

The protocol describes a new method to disaggregate human tissues and to create autologous micro-grafts that, combined with collagen sponges, give rise to human bio-complexes ready to use in the treatment of skin lesions. Further, this system preserves cell viability of micro-grafts at different times after mechanical disaggregation.

This video describes the detailed protocol for isolating melanoma-containing murine dorsal skin, followed by cryo-embedding to prepare a frozen skin tissue block. The cryo-embedded tissue block can be sectioned and microscopically examined to study melanoma progression.
FAQs
These steps divide the separation task. Careful dissection removes and organizes the tissue, mechanical disruption breaks it into smaller pieces, and enzymatic digestion releases cells from the extracellular matrix. Using the steps together helps generate separable cellular or tissue fractions while supporting recovery of viable material for later cancer research analyses.
Viable material allows isolated populations to remain suitable for controlled biological study after removal from the intact organism. This is important when researchers need to examine tumor-associated biology, establish cell cultures, evaluate experimental treatment responses, or develop models of skin tumor behavior. Poor preservation could limit the usefulness of these downstream investigations.
Separating these populations helps researchers relate observed findings to particular tissue compartments rather than treating skin as a single, uniform sample. That distinction supports comparisons between normal and cancer-associated biology and enables focused examination of cellular interactions, tumor initiation, invasion, and treatment responses within the relevant fraction.
A basic workflow begins with careful tissue dissection, followed by mechanical disruption and enzymatic digestion to release material from the extracellular matrix. The resulting preparation can then be separated or examined as epidermal, dermal, or tumor-associated fractions. These fractions provide defined starting material for subsequent laboratory analyses and model development.
Isolated skin material can serve as a starting point for cell culture, molecular profiling, and development of experimental models. These uses allow researchers to study skin biology outside the intact organism, characterize cancer-associated populations, and investigate how tumors develop or respond to experimental treatments using material derived from defined tissue fractions.
The method provides access to tissue components needed to examine several stages of cancer biology, including tumor initiation, invasion, and interactions among cellular populations. Researchers can also use the recovered material to assess responses to experimental treatments. In this way, isolation connects tissue-level samples with controlled studies of tumor behavior and therapeutic effects.
