This study observed that numerical chromosomal aberrations were more common in men with severe male factor infertility and azoospermia compared to those with other sperm quality issues, while chromosomal translocations were significantly associated with oligoasthenozoospermia, highlighting important genetic counseling considerations.

This study developed a biocompatible hair-dyeing technology using a dark polyphenol complex, which demonstrated effective hair coating, improved mechanical strength, and strong antioxidant properties while maintaining high cell viability.

This study introduced a volar skin excisional wound model that closely mirrors human wound healing and supports evaluation of skin regeneration with multiple appendages and innervation.

In this study using mice, researchers found that the Piezo1 channel regulates metabolic changes and immune cell infiltration during skin growth under tension, with altered expression of glycolysis-related genes and increased macrophage activity observed in stretched skin.

This study utilized computational approaches to screen natural compounds targeting a non-androgen pathway involving PIEZO1 and MLCK for treating androgenetic alopecia, identifying several potential candidates for further validation but making no clinical claims.

This in silico study identified potential natural product compounds targeting a non-androgen pathway for promoting hair growth, but further laboratory validation is necessary before any clinical claims can be made.

This study identified candidate compounds from a natural-product library that may interact with the PIEZO1 and MLCK pathways, potentially countering a non-androgen cause of hair follicle miniaturization, all based on computer simulations; experimental validation is necessary.

In this study, researchers reported that hair follicle stem cells maintain quiescence through a PIEZO1-dependent mechanism that senses mechanical forces and translates them into localized calcium influx, involving a transcriptional network that regulates cell adhesion and cytoskeleton-related genes.

This study suggests that bioactive ceramics could be an effective universal strategy for treating musculoskeletal disorders by targeting the Piezo1-modulated intracellular calcium pathway during bone and muscle formation.

This review discusses how aging affects hair follicle stem cells and their environment, contributing to hair loss, and explores strategies to promote hair regrowth, but reports no new results.

Tissue stiffness affects sweat gland development by guiding cell differentiation through specific signals.

This study combined spatial and single-cell transcriptomics to identify that hypercontractility of the connective tissue sheath activates PIEZO1 in hair follicles, leading to miniaturization in male androgenetic alopecia, and found that inhibiting this contraction improves hair growth in models.

In this study, PDLLA treatment in middle-aged mice was observed to enhance hair growth by increasing macrophage M2 polarization and hair follicle stem cell proliferation, potentially rejuvenating the skin's microenvironment and offering a novel approach for age-related hair loss.

This study found that targeting connective tissue sheath contraction with an MLCK inhibitor may improve hair growth in androgenetic alopecia by reducing premature hair regression caused by ectopic apoptosis of hair follicle progenitor cells.

Hair shaft miniaturization leads to hair follicle stem cell loss, suggesting Piezo1 as a potential treatment target.
