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 tribuloside, a flavonoid from Tribulus terrestris L., enhances melanin production in human melanocytes, zebrafish, and human skin samples without causing toxicity, potentially through inhibiting PDE to increase cAMP levels and promote the melanin biosynthesis pathway.

This review discusses three newly identified forms of epidermolysis bullosa related to mutations in DST-e, EXPH5, and ITGA3, offering insights into their genetic and clinical characteristics but reports no new clinical results.

This study found that Super Merino sheep have a higher wool follicle density, finer fleece, and distinct gene expression compared to Small Tail Han sheep, which may inform future breeding and genetic interventions.

This study observed that adipose-derived stem cells modified with trichogenic factors have similar properties to dermal papilla cells and show enhanced hair regeneration potential compared to unmodified adipose-derived stem cells.

This study investigated the genetic basis of coat color variation in cattle using skin transcriptome and whole-genome analyses, identifying the ASIP gene as a significant determinant that is differentially expressed and under strong positive selection in black and brown cattle breeds.

This review highlights that both human-derived and plant-derived exosomes show anti-inflammatory and antioxidant properties, with human exosomes being better for targeted medicinal treatments due to their ability to transport healing drugs, while plant exosomes are more scalable and cost-effective for cosmetic applications.

This study reviews the regenerative potential and clinical applications of exosomes derived from mesenchymal stem cells in conditions like COVID-19, alopecia, skin aging, and osteoarthritis, highlighting their role as a promising tool in regenerative medicine.

In this study, researchers found that the synthetic stress hormone dexamethasone caused opposite effects on hair growth-related proteins, reducing SFRP2 and increasing SFRP3, which respectively stimulate and inhibit hair follicle cell proliferation in human dermal papilla cells.

This study found that high TSPEAR expression in colorectal cancer was associated with poor prognosis and correlated with various tumor and immune-related factors.

This study found that elevated TSPEAR expression in colorectal cancer was associated with poor overall prognosis and correlated with tumor infiltrating immune cells, suggesting its potential as a predictive biomarker.

This study found that Nubian ibex have developed genetic adaptations in response to their desert environment, including enhanced skin barrier, DNA repair, viral response, and metabolism of toxic compounds.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This study introduced a novel in vitro assay for tracking melanosome transfer between melanocytes and keratinocytes, facilitating the quantification of melanin transfer and supporting the role of filopodia as a conduit.
