Graft rejection in a hand transplant may trigger hair loss due to autoimmune responses.

This study observed that both autogenic and xenogenic PRP improved graft viability in rabbits compared to control, with autogenic PRP showing better histopathological results.

In this study, the combination of keratin-gelatin from poultry feathers promoted early acceptance and viability of full-thickness skin mesh grafts in experimental dogs compared to other treatments.

This case report describes how a combined nude and hair-bearing full-thickness skin graft was used after micrographic surgery to achieve a cosmetically satisfactory reconstruction of a large eyebrow defect.

This study demonstrated that cultured human dermal papilla cells can induce full hair follicle formation when combined with neonatal foreskin keratinocytes in a grafted dermal-epidermal construct on mice.

This study found that the peptide TSN6 increased epidermal thickness and promoted hair follicle formation in dermal–epidermal composites grafted onto nude mice, with TSN6-treated composites showing more hair follicles and retained grafts compared to control groups.

This review evaluates the clinical use of composite dermal-epidermal skin substitutes, with a focus on advancements such as the "BioMask" for facial skin trauma, highlighting the potential of 3D bioprinting and bioengineered skin in improving wound treatment and reconstruction.

In this study, researchers used a 3D printing technique to spatially pattern human dermal papilla cell spheroids in a collagen matrix, enhancing skin and hair regeneration in a mouse model, with notable upregulation of key genes for hair follicle formation compared to traditional cell cultures.

This study concluded that keratin-gelatin composite films were more effective than bFGF-gelatin films in promoting early and uncomplicated wound healing in dogs, observing improved epithelialization and graft acceptance.

This study found that keratin-gelatin composite films effectively promoted early wound healing and full-thickness skin graft acceptance in dogs, outperforming bFGF-gelatin films.

This study reports that reconstructing perioral soft tissue defects with submental tissue resulted in satisfactory aesthetic outcomes and minimal donor-site morbidity.
