This study found that recombinant murine IL-36α increased the number of regenerated hair follicles and accelerated wound healing in a mouse model of wound-induced hair follicle neogenesis.

In this study, the researchers developed a new protocol using human-induced pluripotent stem cells to efficiently create skin hair follicle organoids, which may aid in optimizing hair follicle growth and exploring treatments for alopecia.

In this study, researchers found that CD4 is expressed on murine K5⁺ keratinocytes, and its expression is crucial for maintaining epidermal stem cell balance and wound repair capacity, particularly during aging.

This study found that SMAD2 overexpression in human hair follicle stem cells promoted differentiation and apoptosis while inhibiting proliferation, and Smurf2 upregulation limited mouse wound healing by suppressing the SMAD2/NANOG/DNMT1 axis.

This study found that mammary resident macrophages regulate mammary epithelium cell division and development, with implications for maintaining mammary stem cell activity and homeostasis.

This study found that isolated hair follicle outer root sheaths from mice can regenerate new dermal papillary structures in vitro, with stem cells and neutrophils playing key roles in the regeneration process.

This study suggests that with aging, mouse corneal renewal increasingly relies on Lrig1+ stem cells as CD44 expression and Wnt activity decline.

This study provides a comprehensive platform to explore stem cell interactions regulating hair follicle growth, revealing key signaling pathways in epithelial-mesenchymal interactions using advanced RNA sequencing and transgenic reporters.

This review examines beta-catenin's role in stem cell renewal, lineage selection, and tumor formation in the epidermis and reports no new experimental findings.

This study demonstrated that skin organoids derived from human stem cells can model cutaneous tuberculosis, revealing that fibrosis development in Mycobacterium tuberculosis-infected organoids is linked to the PI3K-AKT and AP1 pathways in fibroblasts, and suggesting the potential for antifibrotic treatment evaluation.

This study found that adipose-derived mesenchymal stem cells produced more anti-inflammatory and pro-angiogenic cytokines on electrospun scaffolds, which enhanced wound healing and macrophage activity in a rat model.

This study found that aging in the epidermis disrupts cytokine balance and stem cell function, which may contribute to broader tumor-suppressive mechanisms.

This study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.

This study found that skin-derived precursor cells in mice can originate from both neural crest and somite lineages but show functional similarities regardless of their developmental origins.

This study found that the transcription factor p63 is crucial for horizontal basal cell differentiation in the olfactory epithelium, suggesting a p63-dependent mechanism activates reserve stem cells after injury.

This review discusses current uses and advancements in mesenchymal stem cell-derived conditioned media as a potential regenerative therapy but does not present new clinical findings.

In this study, increased corticosterone from chronic stress prolonged hair follicle stem cell quiescence in mice, inhibiting regeneration, but restoring Gas6 expression overcame this inhibition.

This study explored the complex roles of niche cells in regulating hair follicle stem cells, identifying specific cell functions such as signaling, sensing, and relaying messages, which could provide insights into treating hair loss conditions like androgenetic alopecia and alopecia areata.

This study found that DKK1 and WNT10b are paracrine factors that modulate hair follicle stem cell differentiation inhibition, contributing to androgenetic alopecia by affecting Wnt signaling in androgen-sensitive dermal papilla cells after dihydrotestosterone stimulation.

This study found that lymphatic vessels in mice are important for hair follicle development and organization, as their depletion blocks hair growth.

This review explores recent findings on the roles of melanocyte and melanocyte stem cells in the hair follicle, highlighting their importance for skin health and potential applications in regenerative medicine, but reports no new clinical results.
