This study found that neural stem cell extract enhanced hair growth in mice and cells by stimulating hair follicle niches and activating signaling pathways like TGF-β and BMP.

In this study, researchers observed that mechanosensory neurons initially develop similar morphologies across different skin regions but diverge post-natally, adapting to the type of skin they innervate, with bone morphogenetic protein signaling crucial for forming Meissner corpuscles in glabrous skin.

This study found that FGF5-/- rabbits exhibited a significant long hair phenotype by prolonging the anagen phase, suggesting FGF5 acts as a negative regulator of hair growth.

This study found that UVB irradiation alters skin stem cell niches leading to signs of photoaging, which may be reversed by adipose-derived stem cells through BMP4 pathway modulation and niche remodeling.

Turning scar-forming cells into fat cells can reduce scarring.

This review addresses the limitations of current engineered skin substitutes for burn patients and highlights potential improvements through stem cell biology and skin morphogenesis, but it reports no new clinical results.

In this study, researchers identified gremilin-2 as a highly specific gene to the dermal sheath cup, suggesting it plays a key role in maintaining its properties.

This study found that heat stress in rex rabbits decreased hair follicle density and suppressed related signaling pathways, potentially affecting hair follicle development.

This review discusses historical and recent advances in understanding the embryonic organizer's role in patterning during development, including molecular pathways and future research challenges, but reports no new experimental data.

This study found that Hetian sheep with higher wool density produce more and finer wool, with key genes potentially influencing their wool growth and density.

This study observed that the OCIAD2 and DCN genes in Liaoning cashmere goats have opposite effects on hair growth by interacting with the TGF-β signaling pathway, influencing follicle morphogenesis and periodic changes.

This study identified molecular elements controlling the expression and stabilization of THH protein in hair follicle cells, revealing key mechanisms that support hair shaft development in mice.
