In this study, researchers developed a non-invasive, partially automated protocol for extracting DNA from marmoset hair follicles, resulting in high-quality whole genome sequencing with low chimerism levels, making it a reliable method compared to blood DNA sequencing in these primates.

This review discusses the diverse roles and potential skin health benefits of melatonin, highlighting its anti-inflammatory, antioxidant, and protective effects but reports no new clinical results.

This study found that the PPAR-γ modulator AGED can reverse epithelial-mesenchymal transition in hair follicles affected by lichen planopilaris ex vivo, suggesting potential for treating scarring alopecias.

This commentary highlights the importance of additional sun protection for individuals with alopecia, noting that common headwear like baseball caps may provide insufficient photoprotection for the scalp.

This study found that extracellular ATP released from UVB-irradiated keratinocytes promotes melanin production through the P2X7 receptor, indicating a role for ATP-P2X7 signaling in UV-induced melanogenesis.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.

This study found that vitamin C increased the survival, proliferation, and hair-regenerative potential of adipose-derived stem cells through the MAPK pathway and enhanced hair growth in mice.

This article presents a model for evaluating public R&D that emphasizes measuring capacity-based metrics over traditional outcome-based metrics, using the concept of a Knowledge Value Collective.
