In this study, knockout of B-raf and C-raf genes in mice showed they are not needed for early melanocyte development, but are crucial for maintaining melanocyte stem cells, as evidenced by hair graying due to stem cell depletion.

This study found that resveratrol and fisetin promoted hair growth in mice by inducing telomerase reverse transcriptase expression, which activates hair follicle stem cells and transitions follicles from a resting to a growth phase.

In this study, treatment with human follicular keratinocyte-conditioned media improved the trichogenicity of cultured dermal cells by activating key signalling pathways, suggesting its potential use in cell therapy for hair loss.

This research highlights selenium's critical roles in various biological processes and underscores the potential health impacts of both its deficiency and excess, including increased mortality risk, poor immune function, and neurological issues.

This chapter reviews therapies for skin and corneal regeneration and hair loss, discussing various treatments but presenting no new research findings.

This study found that arachidonic acid may promote hair growth by enhancing dermal papilla cell function and stimulating the anagen phase in C57BL/6 mice.

This paper reviews the advancements and applications of single-cell transcriptomics in animal research, highlighting its potential to enhance understanding of animal nutrition, health, genetics, and disease models.

In this study, researchers developed a method to efficiently derive contractile smooth muscle cells from human hair follicle stem cells using TGF-β1 and PDGF-BB, which may advance vascular tissue engineering.

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

This study found that the PSEN1-P242LfsX11 mutation in hidradenitis suppurativa influences cytokine and chemokine expression in macrophages, potentially affecting inflammatory responses.

This study reported that compounds isolated from Alpinia zerumbet significantly promoted hair cell growth and exhibited anticancer activity in cell cultures, suggesting potential as treatments for alopecia and cancer.

This study found that thymus transplantation in infants with FOXN1 deficiency led to T-cell reconstitution and functional immunity, resolving serious infections and cytopenias.

This study found that obesity in women may impair endometrial stromal function and contribute to reproductive complications, possibly due to metabolic influences rather than immune cell differences.

In this animal study on albino rats, researchers reported that Tribulus terrestris extract significantly reduced liver damage markers caused by cyproterone acetate, suggesting a protective effect on liver function against this drug's hepatotoxicity.

This study found that COVID-19 infection disrupts spermatogenesis, alters testicular cell populations, and may impact male fertility by causing long-term changes in testicular function and reduced sperm quality, as observed even in patients who have recovered from the acute phase of the infection.

This study found that for optimal ADSC viability during short-term storage, using 10% human serum at 4°C and utilizing the cells within 2 hours is most effective.

This study found that Brigatinib-loaded nanospanlastics demonstrated enhanced cytotoxicity against lung cancer cells and improved drug stability and release compared to free Brigatinib.
