This study detailed the structure and amino acid composition of sheep trichohyalin, noting its presence in various tissues and suggesting a possible functional role beyond structural support in hair follicles.

In laboratory research, investigators found that apoptotic vesicles from interleukin-10-treated fibroblasts promote wound healing and reduce fibrotic scarring by enhancing mitochondrial function, modulating collagen composition, and inhibiting the Hedgehog signalling pathway, offering potential for regenerative medicine applications.

This review discusses recent findings on the plasticity and regulation of epithelial stem cells and reports no new experimental results.

This review discusses new developments in understanding the structure and properties of keratin fiber cell membrane complexes, without reporting new experimental results.

This study by Pérez-Oliva et al. explored how Mahogunin Ring Finger-1 (MGRN1) affects melanocortin-1 receptor (MC1R) signaling, suggesting that MGRN1 competitively inhibits Gαs binding to MC1R, influencing pigment production.

This study found that sensitive scalp is characterized by increased pH levels, redness, altered sebum composition, and a disrupted microbiome, suggesting these features could inform treatment approaches.

This review explores recent insights into the diverse cell populations involved in skin development, homeostasis, wound healing, and cancer progression but reports no new results.

This review discusses how circadian clocks may influence diverse physiological functions beyond their established role in daily timekeeping, but it reports no new experimental findings.

This review highlights recent advances in understanding how the extracellular matrix regulates epidermal stem cell fate, emphasizing the importance of the hair follicle stem cell niche, but reports no new empirical findings.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.

This study used cashmere goats to reveal distinct intermediate states of dermal papilla cells, each with specific roles in hair growth, shedding, and regeneration.

Two new compounds can block androgen receptor activity in different ways and may lead to new treatments for androgen-related diseases.

This review discusses the role of collagen XVII in maintaining stem cell niches and its impact on skin aging and wound repair, without reporting new clinical results.

This study discusses how different modes of regulated cell death in keratinocytes affect skin stem cell niches, and their role in skin inflammation, injury repair, and cancer, based on findings from human dermatological conditions and experimental mouse models.

In this study, researchers found that in growing skin tissue, epidermal wound healing occurs at the expense of normal skin development, as it impairs hair follicle growth and does not activate tissue morphogenesis genes.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

This article discusses the coordinated roles of different epidermal stem cells and other cell types in the skin's wound healing process and reports no new experimental results.
