Platelet-rich plasma (PRP) is an effective treatment for hair loss that involves scalp injections and requires ongoing maintenance.

This review explores the role of TGF-β superfamily pathways in stem cell environments and their implications for tissue regeneration and cancer development, reporting no new experimental results.

This study found that Polycomb Repressive Complex 1 is crucial for maintaining stem cell identity across different lineages, but its loss results in varied transcriptional outcomes depending on the tissue context.

This review discusses potential strategies for rejuvenating miniaturizing hair follicles in androgenic alopecia but reports no new clinical results; it explores the idea of using DHT-resistant follicle preservation for long-term hair maintenance.

This study suggests that translation levels may determine the proliferative potential of cultured human keratinocyte colonies, affecting their differentiation during epidermal maintenance and repair.

This review discusses the roles and characteristics of skin stem cells, their niches, and signaling pathways in skin maintenance, aging, and cancer, highlighting their potential in therapeutic applications but presenting no new clinical findings.

This review discusses how the p53 tumor suppressor gene helps maintain adult tissue homeostasis by promoting the removal of DNA-damaged cells, with implications for treating age-related diseases and p53-deficient cancers; it reports no new results.

This study observed that Bmi1+ central corneal progenitor cells do not contribute to wound healing in mice, which instead rely on epithelial cell rearrangement and migration to close abrasions.

This study suggests that epithelial-derived Pop-Up Keratinocytes (ePUKs) may be a promising cell source for regenerative medicine due to their specific phenotypic traits and their influence on wound healing.

In this study, researchers found that quiescent stem cells resist immune attack due to downregulated antigen presentation, which may help explain the immune evasion of early cancer-initiating cells.

Loss of COL17A1 causes hair follicle stem cells to age and leads to hair loss.

This study reviewed evidence suggesting that the loss of dermal white adipose tissue (dWAT) during menopause may be linked to decreased estrogen levels, potentially affecting skin health, and discussed non-hormonal treatments, like magnolol, that might help restore dWAT and improve menopausal skin changes.

This review examines regulatory mechanisms of quiescent stem cells in tissue homeostasis, drawing on observations from the intestine and other self-renewing tissues, without presenting new data.

This review discusses the role of stem cell heterogeneity and compartmentalization within the epidermis and highlights their significance as niches for neighboring cells, without reporting new experimental results.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

In this study, fibroblasts from long-term skin biopsy cultures retained their ability to reprogram into induced pluripotent stem cells after 16 months, despite undergoing transcriptional changes and decreased proliferation rates over successive generations.

This review discusses the regeneration capabilities of various vertebrate tissues, focusing on the unique ability of certain species to regenerate teeth and lens, and reports no new results.

This review discusses the varied roles of Wnt7a in development, tissue homeostasis, and cancer, reporting no clinical results; the authors emphasize the need for further investigation on its roles in inflammation and fibrosis.

This study concluded that placental mesenchymal stem cells from aborted fetal tissue may serve as an in vitro model for studying spontaneous abortion mechanisms and potential regenerative therapies due to their abnormal gene expression and differentiation capabilities.

This study explored the effects of a common Hutchinson-Gilford progeria syndrome mutation in an inducible mouse model, revealing skin abnormalities similar to those in affected patients.

This review discusses the origin, characteristics, and therapeutic potential of melanocyte stem cells in skin pigmentation disorders and reports no clinical results.

In this study, the researchers reported that Notch/CSL signaling is crucial for hair follicle differentiation, with Wnt5a signaling and FoxN1 acting as mediators in mice.

This review article examines recent studies on the role of diverse immune cells in forming an active niche for hair follicles, offering new insights into hair growth and related diseases.

One type of progenitor cell can maintain normal skin in mice.

This study reports that the novel small molecule IM176OUT05, by modifying stem cell metabolism, promoted hair regrowth and increased hair follicle numbers in mice.

This study found that skin-resident Treg cells regulate hair follicle stem cell proliferation and differentiation through the Jag1-Notch signaling pathway, influencing hair regeneration.

This review discusses the role of the hairless protein (HR) in alopecia and cancer, noting its potential importance in cancer cell growth and survival, and reports no new experimental results.

This review discusses experimental data, technologies, and genetic factors related to stem cell niches, highlighting their role in tissue regeneration and diseases, but reports no new results.

This study found that Wnt/β‐catenin signaling influences the hair follicle regeneration process by prompting quiescent stem cells to enter the cell cycle and is necessary for maintaining the stem cell pool.

This article argues that lineage labeling with genetic markers is the gold standard for identifying epithelial stem cells, contrary to the view that in vitro methods alone are sufficient.
