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 demonstrates a method for grafting human skin onto an immunodeficient mouse with a suppressed neutrophil response. The method involves applying human split-thickness skin to the mouse's graft bed, sealing it, and covering it for recovery. Eventually, the human skin adheres to the mouse's skin, establishing vascularization and circulation, resulting in a successful skin xenograft.

Traditional procedures for the isolation of soluble type 1 collagen (COL1) require about 10 days from start to finish because of lengthy buffer incubations and laborious resuspensions of fibrils. Here, we describe a means to purify COL1 from small dermal biopsies in less than 3 hr.

The aim of this study was to develop a murine model of burn wound healing. A thermal burn was induced on the dorsal skin of mice using a preheated brass template. Burned tissue was debrided and overlaid with a skin graft harvested from the tail of a genetically similar donor mouse.
FAQs
A well-vascularized wound bed supports graft attachment by providing access to nutrients as the transplanted tissue establishes contact with the recipient site. Preparation therefore focuses on creating conditions that allow the graft to connect with the wound rather than placing it over poorly prepared tissue. Successful attachment promotes continued coverage and supports subsequent re-epithelialization.
Thickness and orientation must be controlled so the graft can match the wound and maintain its intended tissue arrangement. Trimming helps shape the graft for coverage, while preserving the correct orientation supports contact between the prepared graft and recipient bed. These variables are important because poor matching or positioning can interfere with attachment and the restoration of surface coverage.
Meshing modifies the graft so it can conform to the wound rather than remaining as an unadapted sheet. This preparation is especially relevant when the wound requires a graft to match its dimensions or contours. By incorporating meshing into the preparation process, clinicians and bioengineers can address fit while also considering fluid accumulation and the conditions needed for graft take.
The process combines surgical handling of donor and recipient tissues with bioengineering concerns such as controlled thickness, orientation, wound-bed preparation, and biomaterial design. These shared principles help explain why graft preparation is relevant beyond immediate reconstruction. They also support development of tissue-engineered skin and research on regenerative wound healing, where material and tissue properties influence coverage and re-epithelialization.
Preparation begins by selecting and harvesting suitable donor skin, then adapting the graft through trimming or meshing. Its thickness and orientation are controlled before placement. In parallel, the recipient wound is prepared to provide a well-vascularized bed. Together, these steps create a better match between graft and wound while addressing attachment, fluid accumulation, infection risk, and later re-epithelialization.
The recipient wound should provide a well-vascularized surface, because graft attachment depends on access to nutrients after placement. The graft must also be appropriately shaped, oriented, and controlled in thickness for the target wound. Attention to these conditions helps limit fluid accumulation and infection risk, two factors identified in preparation as potentially affecting graft take and subsequent healing.
Skin graft preparation supports reconstructive surgery and burn treatment by organizing donor tissue and recipient-wound conditions for restoring coverage. In bioengineering, the same principles inform tissue-engineered skin development, biomaterial research, and studies of regenerative wound healing. Outcomes of interest include graft take, reduced fluid accumulation and infection risk, and re-epithelialization over damaged tissue.
