Fractional skin harvesting (FSH) was designed for skin grafting. a Full-thickness skin columns harvested with a 19-gauge coring needle from the donor. (Cohen et al. 2014) Epidermis; (Graber et al. 2017) dermis including adnexal structures; (Global Point Of Care Diagnostics Market will reach USD 40.50 Billion by 2022: Zion Market Research n.d.) subcutaneous fat. Each mark on the ruler in the photograph spans 1 mm. b The recipient site i) before and ii) after the 8-week recovery time. i) Human skin columns were applied in random orientation to a full-thickness wound on the dorsal skin of a mouse; arrow highlights the epidermal head of one skin column. ii) The recipient site formed a ‘fishing net’ in the middle (arrow) after recovery. c The FSH resulted in samples with smaller surface area and mass than conventional split-thickness skin graft. Rσ = surface area ratio; Rm = mass ratio. Pictures retrieved/adopted from Tam et al. 2017. All figures are under a Creative Commons Attribution 2.0.
