Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

This study found that removing PPARγ specifically from mouse adipose tissue led to severe fat loss, insulin resistance, diabetes, and associated metabolic abnormalities.

This study found that the BMP antagonist noggin induces hair growth in postnatal skin by neutralizing BMP4's inhibitory activity, potentially mediated by changes in Shh expression.

This review discusses advancements in artificial skin for wound treatment and reports no new clinical findings; the authors highlight the potential of new biomaterials to enhance future skin replacement therapies.

This review discusses the shared molecular and cellular processes in the early development stages of skin appendages like hair follicles, teeth, and mammary glands, reporting no new results.

This study found that telocytes are present in the human dermis, suggesting a potential role in skin homeostasis, remodeling, regeneration, and repair.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This review explores the role of TGF-β superfamily pathways in stem cell environments and their implications for tissue regeneration and cancer development, reporting no new experimental results.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This study found that disrupting Adam10 in the epidermis led to severe skin and multi-organ abnormalities, implicating Adam10 as crucial for proper Notch signaling and skin maintenance.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

This review explores how adipose-derived stem cells contribute to skin homeostasis and highlights recent advances in their clinical applications in dermatology, but it reports no new clinical results.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This study found that applying dexamethasone to mice induced catagen-like follicle changes significantly earlier and more consistently than a vehicle, such changes being useful for studying hair follicle regression.

This review discusses the mechanisms and pathways of FGFR signalling and its roles in development, disorders, and therapeutic targeting, but reports no new clinical results.

This study found that the protein MIM is crucial for maintaining cilia and Sonic hedgehog signaling in mesenchymal cells by counteracting Src-mediated phosphorylation of Cortactin, impacting hair follicle formation.

This study highlights the potential increased frequency of advanced liver disease in obese PCOS patients with NAFLD and underscores the importance of lifestyle modifications as initial treatment.

This study found that treatment with mesenchymal stem cell extracellular vesicles enhanced hair growth in mice and stimulated dermal papilla cell activity and growth factor production in vitro.

In this study, 96% of men with persistent sexual side effects from finasteride reported continued dysfunction after discontinuation, suggesting these effects may endure long-term.
