Collagen membranes improve melanocyte growth for treating skin depigmentation.

Skin grafting can help repigment vitiligo, but it's less effective for widespread cases due to the Koebner phenomenon.

Fibroblasts can be turned into melanocytes for potential skin treatments.

Condensed nanofat with fat grafts effectively improves atrophic facial scars.

Advancements in creating skin grafts with biomaterials and stem cells are promising, but more research is needed for clinical application.

Technique effectively treats deformities, achieves re-pigmentation, and releases scar contractures.

The survival rates of hair grafts are similar regardless of how they are trimmed.

Transplanting melanocyte stem cells from hair follicles can effectively treat vitiligo.

Melanocyte stem cells from non-affected skin in vitiligo patients can become functional melanocytes for potential therapy.
