This article reviews how aging affects skin and stem cells, but it contains no new research findings.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

Drugmakers are optimistic about targeting the Wnt pathway for new treatments despite past challenges.

This study observed that exosomes from adipose mesenchymal stem cells overexpressing hepatocyte growth factor significantly improved liver function and reduced fibrosis in mice with experimentally induced liver injury.

This study revealed that Vav2 and Vav3 play roles in regulating hair follicle bulge stem cells in normal conditions and cancer stem cell activation and remodeling in mice.

This study found that overexpressing the gene Thymosin β4 (Tβ4) can promote the growth and development of secondary hair follicle dermal papilla cells in cashmere goats, suggesting its potential as a target for increasing cashmere production.

This study found that Rab27a and Rab27b play opposite roles in hair growth, with Rab27a knockdown suppressing and Rab27b knockdown promoting hair growth in models.

This study found that ARHGEF3 is crucial for hair follicle development in mice, as its absence leads to defects in placode compaction and impaired follicle downgrowth, highlighting its role in regulating cell shape rearrangements during embryogenesis.

This study found that TRM21 acts as a positive regulator of flavonoid biosynthesis at the translational level in Arabidopsis, leading to changes in root hair growth and a decrease in flavonoid content when TRM21 is mutated.

This study identifies two new proteins, CCDC22 and CCDC93, essential for root and root hair growth in Arabidopsis, and demonstrates their genetic link to a VTI13-dependent vacuolar trafficking pathway.

This study found that in women with PCOS, lipid-induced NFκB activation is independent of obesity and exhibited evidence of LPS tolerance in combination with obesity and hyperandrogenism.

This study found that human scalp hair follicles can internally operate a Cori cycle, synthesize glycogen in the presence of lactate, and modulate growth through glycogen phosphorylase activity.
