This study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.

This study reviews the structural and functional aspects of cell-cell and cell-matrix junctions in sebocytes, emphasizing their roles in sebocyte differentiation and sebum secretion, and how these processes may change in pathological conditions, potentially providing insights for new skin disease therapies.

This study reports that mesenchymal stem cell-conditioned medium promoted dermal cell migration and proliferation, enhancing wound healing but not direct hair growth, in vitro and in adult mouse models.

This study found that minoxidil increases cytosolic-free Ca2+ levels and induces cytotoxicity in PC3 human prostate cancer cells, with the cytotoxicity occurring in a Ca2+-independent manner.

This study used transgenic mice to show that disrupting TGF-β signaling in K14+ progenitor cells led to increased stem cell proliferation in the tongue.

This study observed that in adult mice, a cell-autonomous size control mechanism involving the RB pathway determines the timing of S phase entry in epidermal stem cells based on their size, while external microenvironment factors influence growth rates but not this intrinsic coupling.

This study found that RSPO1 mutations in patients with a 46XX disorder of sexual development contribute to impaired skin integrity and increased risk of squamous cell carcinoma in areas subject to friction.

This study found that DNA flow cytometry effectively evaluates physiological and hormonal influences on cell cycle kinetics of human anagen hair bulbs, with increased S phase cells observed in male pattern baldness, hirsutism, and hyperthyroidism.

Certain genes influence the direction of hair whorls on the scalp.

This study found that human induced pluripotent stem cells differentiated precisely to express certain markers during a specific window could enable successful hair follicle generation when transplanted.

In this study, ebastine significantly increased the proliferation of human follicle dermal papilla cells and may contribute to hair regrowth by activating the ERK signaling pathway.

This study found that deer antler aqueous extract may promote hair growth in mice by extending the anagen phase and increasing cell proliferation in the hair follicle region.

This study reveals that stem cell descendants in mouse hair follicles can return to their niche to retain stemness and function as primary stem cells for future hair cycles.

This study found that scanning electron microscopy with argon sputter etching visualizes hair lipids at the cell membrane complex as distinctive convex structures, shedding light on their role and localization in human hair.

In this study, human umbilical cord mesenchymal stem cells and their conditioned medium significantly improved symptoms in mouse models of atopic dermatitis, potentially through exosome-dependent pathways, suggesting a cell-free therapeutic strategy.

This study by Dr. Manka and colleagues reported that thyroid hormones play a significant role in regulating hepatic stellate cells, influencing liver fibrosis progression via TGFβ signaling. They found that TRα signaling might enhance scar-free tissue regeneration, offering potential pathways for targeted liver fibrosis treatments.

In this study, researchers reported that a newly developed interferon-γ release assay for cell-mediated immunity to SARS-CoV-2 nucleocapsid peptides demonstrated high sensitivity and specificity, making it a robust tool for routine diagnostic tests and potentially useful in predicting clinical outcomes after pathogen re-exposure.

This study reported that bio-pulsed avian-derived mesenchymal stem cell extracellular vesicles significantly improved cell proliferation, wound healing, and gene expression in human skin fibroblasts and hair follicle cells.

This study found that knocking out the integrin β1 subunit in induced pluripotent stem cells enhanced their migration and improved their wound-healing effects in a mouse model.

This study found that STAT3 directly inhibited the activity of the sheep FST gene promoter, consequently reducing cell proliferation and promoting a better understanding of hair follicle development mechanisms.

This study reported that plant-produced basic fibroblast growth factor effectively promoted cell proliferation and collagen production in vitro, suggesting potential applications in cosmetics for antiaging and hair growth.

This study found that Poria cocos extract may enhance human follicle dermal papilla cell proliferation through the AKT signaling pathway, indicating its potential for hair growth promotion.

This study found that a 12-week supplementation with MePL, a solution of miliacin encapsulated within polar lipids, significantly reduced hair density in the telogen phase and improved scalp dryness and hair brightness in women with telogen effluvium.

This study found that mouse hair follicle stem cells in a quiescent state exhibit greater chromatin dynamics and de-differentiation potential, suggesting higher cell fate plasticity compared to their proliferative or differentiated counterparts.

In this study, the type II subunit of porcine hair keratin was found to significantly inhibit the differentiation of PC12 neural cells compared to the crude extract and type I subunit, although cell proliferation was unaffected.

This study demonstrates that encapsulating cell-free fat extract in a gelatin methacrylate hydrogel enhances flap repair by sustaining angiogenesis, reducing oxidative stress, and offering favorable biocompatibility in a murine skin flap model, thereby advancing potential clinical flap necrosis treatments.

In this study, researchers used quantitative fate mapping to investigate how the infundibulum, part of the epidermis, is maintained during adulthood, finding that progenitors maintain this tissue through stochastic cell fate choices, with cells at the bottom providing transient support during hair growth phases.

In this study, researchers found that pregnant mice exposed to excessive androgen led to thinner ventricular walls and cardiac hypertrophy in offspring, suggesting that prenatal androgen exposure adversely affects cardiac health through reduced cardiomyocyte proliferation.

This study found that stem cells can temporarily act as non-professional phagocytes during hair cycle regeneration by clearing apoptotic cells through a process requiring local lipids and retinoids for activation, providing insights into their dual role in maintaining tissue integrity.

This study found that patients with hidradenitis suppurativa had significantly higher levels of cell-free DNA in their serum compared to healthy controls, suggesting its potential as a biomarker for the disease.
