This study found that IMT-P8, a novel cell-penetrating peptide, effectively facilitated the dermal delivery of proteins and peptides in mouse skin and cell lines, suggesting potential for topical applications in cosmetics and skin diseases.

This study found distinct gene expression profiles in alopecia areata-affected skin, suggesting T-cell mediated immune responses and unique gene profiles between different stages of the disease.

This review examines the location and markers of hair follicle stem cells, finding that they are primarily located in the bulge region and can contribute to various skin structures, but challenges remain in distinguishing them from their progeny.

This study found that RANK-RANKL signaling regulates hair renewal and epidermal homeostasis in mice, revealing its role in initiating hair growth cycles and maintaining skin cell activity.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

This study found that FOXN1 haploinsufficiency is a significant genetic factor causing T cell lymphopenia at birth, linked to reduced thymic function in both humans and mice.

This study highlights that the mammalian target of rapamycin complex 2 (mTORC2)-Akt signaling axis is essential for hair follicle stem cells to return to their niche and regenerate effectively by regulating metabolic pathways.

This review discusses the enhanced understanding of how stem cell niches respond adaptively to systemic signals, aging, and local perturbations, but reports no new research findings.

This study found that a newly developed injectable hydrogel combined with human umbilical cord-mesenchymal stem cells significantly accelerated wound healing and reduced inflammation in full-thickness cutaneous wounds.

This study found that cultured dental papilla cells from various mammals can induce hair follicle regeneration and influence tissue formation, with outcomes dependent on donor age, tooth type, and host environment.

This review discusses the effects of valproic acid on immune cell activation and gene expression, potentially influencing infection outcomes and suggesting its promise for autoimmune and hypersensitivity condition management.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

In this study, patients receiving adipose-derived stromal vascular cell transplantation for alopecia areata experienced significant hair regeneration, increased growth, and improved hair quality after 3 and 6 months, indicating potential efficacy of this stem cell-based therapy for hair loss.

This study found that using 3D Gel-C6S-HA scaffolds seeded with VEGF165-modified rat hair follicle stem cells enhanced angiogenesis and vascularization in tissue-engineered skin, improving wound healing.

In this study, researchers differentiated induced pluripotent stem cells into cells with dermal papilla-like properties, demonstrating their potential role in hair follicle bioengineering and drug testing for hair growth.

This review discusses the roles that mesenchymal stem cells may play in reepithelialization of wounds, but reports no new clinical results.

The researchers reported that in mice, prolactin signaling in the skin epithelium inhibits hair follicle stem cell activation, promoting quiescence during periods of high serum prolactin like pregnancy and lactation.

This study found that GLI2 plays a key role in activating follistatin, an activin/BMP antagonist, in response to hedgehog signaling in human epidermal cells, with implications for hair follicle development and basal cell carcinoma.

This review synthesizes recent findings on the hair follicle stem cell niche and its complex interactions, exploring potential pathways for developing new hair growth therapies; it reports no new clinical results.

This review discusses the role of the TCL1 transgenic mouse model in understanding chronic lymphocytic leukemia biology and highlights the importance of exploring new pathogenetic and therapeutic targets.

In this study, transgenic male mice over-expressing the androgen receptor in mesenchymal stem cells showed reduced fat mass and improved glucose clearance, suggesting enhanced androgen sensitivity may alter body composition.

This study found that Ldh activity in hair follicle stem cell-mediated squamous cell carcinoma is not necessary for tumorigenesis, as its modulation did not affect the cancer's development or characteristics.

This study found that the dermal papilla of the hair follicle regulates stem cell quiescence and regeneration by modulating Shh and Wnt signaling pathways, highlighting the importance of signaling cross talk in regeneration.

High doses of finasteride cause cell growth and tumors in mice.

This study found that in mouse skin, the activation of stem/progenitor cells is synchronized across different niches during growth, with the glutamate transporter SLC1A3 playing a crucial role in this process.
