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 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.

FAQs
Preserving tissue planes keeps neighboring layers and structures in their anatomical relationships while the specimen is opened. That organization allows investigators to associate visible features with the epidermis, dermis, subcutaneous tissue, blood vessels, nerves, and appendages rather than viewing isolated fragments. In bioengineering, this relationship helps connect skin architecture with measured material properties and functional performance.
Controlled incision provides access to deeper structures while reducing unnecessary disruption of the specimen. The approach supports deliberate separation along tissue planes, which helps maintain anatomical relationships for examination and measurement. This matters when the preparation will be used for imaging, biomaterial testing, or comparison with engineered skin, because specimen quality influences how confidently observations can be interpreted.
Careful handling preserves the arrangement of native tissues and improves specimen quality. A preparation that retains recognizable layers, vessels, nerves, and appendages provides a stronger basis for examining architecture and comparing native tissue with engineered constructs. Consistent handling also supports more reliable imaging and experimental measurements, making differences between samples easier to relate to biological or material behavior.
A basic preparation proceeds through controlled incision, separation along appropriate tissue planes, and careful handling of the exposed specimen. Each stage should maintain the relationships among skin layers and associated structures. After exposure, the preparation can support examination, measurement, or experimental manipulation, depending on the study. Consistency across these stages is especially important for producing comparable specimens.
Researchers use the method when they need native skin organization as a reference for engineered tissues or biomaterials. It can support studies of skin architecture, material properties, wound repair, and integration between engineered and native tissue. The resulting preparation also provides a basis for imaging and validation, helping investigators assess whether a model reflects relevant structural features.
A carefully prepared specimen can reveal the organization of major skin layers and associated structures for examination or measurement. It may also provide material for imaging, biomaterial testing, and validation of skin models. In a bioengineering context, these outcomes help relate anatomical organization to functional performance and evaluate how engineered tissues correspond to native skin.
