In this study, researchers identified a three-step process underlying age-related curved hair from cyclical extension: surface lipid transfer, specific disulfide bond cleavage, and unraveling of α-helices into β-structures, which may inform care strategies to manage hair curvature.

This study observed that hydrophobic modifications of hair matrix proteins significantly alter the humidity-dependent glass transition temperature of human hair.

Collagen scaffolds in cell therapy can transform skin to be more resilient and pressure-responsive.

This review discusses how recent advances in live imaging have revealed the dynamic and adaptable nature of stem cells during various biological processes, and reports no clinical results.

This study found that RSPO1 mutations in patients with a 46XX disorder of sexual development contribute to impaired skin integrity and increased risk of squamous cell carcinoma in areas subject to friction.

This study found that poly(butylene citramalate-co-butylene succinate) copolymers exhibit high toughness, recyclability, degradability, and biocompatibility, achieving complete wound healing with skin and hair follicle regeneration in 7 days.

This case study describes a 14-year-old girl with pili annulati who had fragile hair, which may be due to cavities within the hair shafts as seen in electron microscopic examinations.

This study observed that stem cells from the hair follicle dermis share similarities with bone marrow-derived mesenchymal stem cells and have potential to form neural-like cells under specific conditions.

This review discusses the principles, materials, and applications of melt electrowriting-based 4D printing for creating biomimetic scaffolds, but reports no new clinical results; it highlights recent advancements and remaining challenges in the field.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.

This review outlines the design and engineering of multifunctional hydrogels, emphasizing their evolving biomedical applications, notably in controlled drug delivery, tissue support, and disease management, and discusses their potential for clinical translation.
