TLDR PGA fiber-reinforced collagen sponges improve hair growth and skin structure.
The study explored a modified hair reconstitution method using a collagen sponge scaffold reinforced with polyglycolic acid (PGA) fiber, which was tested in a murine model. The traditional method involved using a silicone chamber for cell transplantation, but issues like leakage and tilting affected hair growth outcomes. The research found that conventional collagen sponges interfered with normal hair follicle formation, whereas the PGA fiber-reinforced collagen sponge facilitated proper skin and hair follicle restructuring. This suggested that PGA fiber-containing collagen sponges could be beneficial for hair reconstitution in both research and clinical settings.
