This study discovered that in *Drosophila*, knockdown of specific storage proteins in adipocytes decreased germline stem cell maintenance, implicating a role for these proteins in adult tissue regulation.

This study demonstrated that disrupting EGFR signaling in mice leads to immune sensitivity compromising the hair follicle's protective environment, but JAK1/2 inhibition can restore this immune privilege and stimulate hair growth, suggesting a potential therapy for scarring hair loss diseases like cicatricial alopecia.

This study found that, despite a major depletion of SOX2-expressing stem cells in the pituitary, there was no effect on endocrine cell homeostasis or response to certain stressors in adult mice.

This review discusses the flexibility and diversity of tissue stem cell systems, particularly focusing on the motility and ligand distribution of spermatogenic stem cells, without presenting new experimental results.

This study found that low concentrations of Asiasarum heterotropoides extract may enhance proliferation of human mesenchymal stem cells from periodontal tissue without affecting cell morphology.

This study found that far-infrared radiation preconditioning significantly enhanced the proliferation, survival, and migration of bone marrow-derived stem cells in vitro, indicating potential therapeutic benefits for cardiac ischemia treatment.

This article reports no new findings as it lacks an abstract.

The researchers reported that disrupting ATRA signaling by deleting RDHE genes in the hair follicle led to altered hair follicle cycles, composition, and gene expression, indicating RDHEs' role in hair follicle signaling coordination.

In this study, a new apple stem cell extract serum significantly improved signs of skin aging and enhanced cell metabolism in human senescent fibroblasts, showing visible effects after one week of use.

This study found that applying adipocyte-derived stem cell conditioned media increased hair count significantly in androgenic alopecia patients compared to saline, suggesting it as a potential treatment, with no adverse effects reported.

This study found that Wnt signaling regulates the symmetric division of adult neural stem cells, increasing their numbers during subependymal regeneration, stroke response, and colony formation.

This research detailed a single-cell atlas showing dynamic hair follicle stem cell states associated with the hair cycle during aging in mice, highlighting differences in chromatin landscape linked to stem cell differentiation and quiescence, and providing a foundation for future exploration of aging reversal.

In this study, researchers found that extrafollicular progenitors marked by Hic1 are the main contributors to reparative fibroblasts in wound repair, with potential to modulate healing outcomes through genetic and pharmacological interventions.

This study found that combining platelet-rich plasma with adipose-derived mesenchymal stem cells significantly improved diabetic wound healing in rats by enhancing angiogenesis and modulating the Notch signaling pathway.

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 study found that conditioned media from human amniotic fluid-derived stem cells may enhance skin regeneration by promoting cell proliferation and migration, and by modulating gene expressions altered by UV irradiation.

In this study on a mouse model of vitiligo, NB-UVB/ADSC combination therapy improved oxidative stress and calcium homeostasis, but the protective effect was reversed by inhibiting Nr2 signaling.

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 review discusses the roles of peripheral nerves in stem cell and immune responses within the skin and hematopoietic system, emphasizing their potential in developing new therapies; it reports no new experimental results.

This review reports limited evidence suggesting that stem cell-based therapies, particularly using human-derived mesenchymal stem cells and exosomes, may be effective for skin rejuvenation, though results are uncertain due to methodological limitations and variability across studies.

This review highlights that collagen XVIIα1's role in maintaining dermal-epidermal junction integrity and hair follicle stem cell maintenance is compromised with age due to reduced levels and increased processing, potentially affecting skin and hair aging.
