Certain compounds can protect hair cells from aging and promote growth.

This study suggests that while cellular senescence impairs epidermal stem cells in aging, it also serves an essential role during embryonic development, highlighting its dual functional nature.

p14ARF and p16Ink4a cause hair follicle stem cell aging and dysfunction.

This study found that mouse hair follicle stem cells use symmetric cell division for maintenance and fate determination, and identified Gata6 as a crucial factor for their differentiation.

Senescent fibroblasts can help start tumors in normal skin cells.

This article discusses the structure and function of the skin's layers, cell types, and tumor development, without reporting new clinical findings, and highlights the growing incidence of skin cancer.

This article discusses the structure and function of the skin, the etiology and increasing incidence of skin cancer, and the types and prevalence of malignant skin tumors, but reports no new research findings.

This review summarizes biological links between aging and androgenetic alopecia, particularly focusing on cellular senescence, and discusses potential therapeutic strategies, but reports no new clinical results.

This study found that in Arabidopsis thaliana, the interaction between extracellular leucine-rich repeat extensins and the receptor-like kinase FERONIA helps control vacuolar expansion, crucial for cellular elongation.

In this study of patients with Androgenic Alopecia, micro-grafts containing HD-AFSCs resulted in significantly improved hair density and follicle count over 11 months compared to a saline solution, suggesting a potential alternative therapy for hair regrowth.

This study identified key cells and pathways needed for the development of touch receptor patterns in mouse skin, notably that certain keratinocytes are crucial for innervation patterns, while Merkel cells and BMP signaling have distinct roles.

This review highlights the limitations of mouse models in human hair loss research and emphasizes the potential of using human cell bioengineered models and artificial intelligence for future advancements, but reports no new clinical results.

This study found that the development of Merkel cell carcinoma from hair follicles in mice can be driven by in vivo reprogramming with ATOH1 and relies on p53 loss for progression.

This article reviews skin regeneration and fibrosis, identifying key cellular and molecular players, and emphasizing the potential to manipulate the postwound environment to promote regeneration over fibrosis.

This review explores regenerative treatment options for non-scarring alopecia, with a focus on the potential of mesenchymal stem cells for hair regrowth, but it reports no new clinical results.

In this study, a single application of autologous cellular micrografts showed short-term favorable responses in up to two-thirds of patients with androgenetic alopecia.

In this animal study, combined cellular therapy significantly improved diabetic wound healing, and probiotics further enhanced these effects by reducing oxidative stress, apoptosis, and inflammation while promoting vascularization and collagen organization.

In this case report, a post-menopausal woman with symptoms such as hirsutism and elevated testosterone underwent surgery, which revealed hormonally active ovarian cellular fibromas, leading to symptom resolution and normalized hormone levels; the authors suggest further exploration of these tumors' hormonal effects.

This study found that sebaceous glands can regenerate after PPARg deletion in adult skin, relying on the hair cycle and FGFR signaling.

This study investigated how secretions from cultured human hair follicle-derived keratinocytes affect gene expression in human follicle dermal papilla cells to understand their signaling interactions.

In this study, PBMCs from women with PCOS showed reduced TNF-α production over time, potentially limiting their antitumor response to breast cancer cell lines compared to healthy controls.
