In this study, a keratin hydrogel improved survival rates and functional recovery in rats with spinal cord injuries, suggesting potential for SCI treatment that merits further investigation.

Corrections were made to a previous work on 3D printing a gel-alginate mix for creating hair follicles, but the main finding - that this method can help grow hair - remains the same.

This review examines advancements in "smart" hydrogel dressings for complex wound healing, highlighting innovations in materials that provide multifunctionality, such as responsive drug delivery and regenerative capabilities. The study also addresses potential challenges in clinical application, like manufacturing and regulatory hurdles.

This review highlights the potential of natural hydrogels as advanced wound dressings, emphasizing their capabilities in mimicking the extracellular matrix, supporting healing, and delivering therapeutic agents for chronic and infected wound care.

This study found that a biomaterial gel made from human hair keratins facilitated nerve regeneration in an animal model, potentially matching the effectiveness of traditional autografts.
