TLDR The new SIS-PEG sponge is a promising material for skin regeneration and hair growth.
The study introduced a novel SIS-PEG biosponge for skin tissue engineering, which improved upon traditional SIS by enhancing cell migration and growth due to its three-dimensional porous structure. The SIS-PEG sponge showed better mechanical stability and resistance to degradation, and it effectively promoted wound healing and hair regeneration in mouse models. The in vivo experiments demonstrated that the SIS-PEG sponge could support the formation of reconstituted skin with hair after 21 days. However, the number of mice used in the study was not specified. The study concluded that the SIS-PEG sponge, especially with a 1:1 ratio of SIS to PEG, holds promise as a biomaterial for skin regeneration due to its structural characteristics, biocompatibility, and ability to facilitate tissue repair and hair follicle regeneration.
