This review discusses the potential benefits and biological activities of MSC secretome for various skin applications, but it reports no new clinical results.

This study demonstrated that combining the Wnt/β-catenin activator CHIR99021 with 3D spheroid culture effectively enriched hair follicle formation in reconstituted human skin.

In this study, researchers developed gellan gum hydrogels functionalized with biomimetic peptides that create a supportive microenvironment for human dermal papilla cells, enhancing their hair-inductive capacity and ability to mimic hair morphogenesis-like events in vitro.

This study found that 3-hydroxypropionic acid improved the function of hair follicle cells under oxidative stress, suggesting potential as a treatment for stress-related hair loss.

This study examined dermal papilla cells from hair follicles, finding that gene expression changes linked to wound healing and stem cell activity align with hair follicle regression, which could inform strategies for hair growth and skin rejuvenation.

This study found that the alkaline degradation process of hair keratin using nucleophilic reagents led to different proportions of reaction products compared to wool, particularly more lanthionine and lysinoalanine residues.

This study demonstrated that dermal papilla cells were more efficiently reprogrammed into induced pluripotent stem cells than dermal fibroblasts, suggesting their potential as a source for iPS cells.

This review explores whether SARS-CoV-2 could trigger or worsen α-synucleinopathies, like Parkinson's disease, by affecting α-synuclein misfolding and aggregation, potentially linking COVID-19 with the development of parkinsonism-like symptoms.

This study found that organoid cultures of human epithelial and mesenchymal cells can produce hair peg-like structures, and their growth is enhanced by minoxidil, suggesting potential for hair drug screening.

This study found that calcium and all-trans retinoic acid affect the proliferation and differentiation of goat hair matrix cells, which are essential for cashmere growth research.
