Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

This review highlights recent advances in understanding how the extracellular matrix regulates epidermal stem cell fate, emphasizing the importance of the hair follicle stem cell niche, but reports no new empirical findings.

This review explores recent insights into how intrinsic gene oscillations and molecular interactions in hair follicle stem cells contribute to their regenerative potential, with potential implications for regenerative medicine, but reports no new clinical results.

This review discusses the role of collagen XVII in maintaining stem cell niches and its impact on skin aging and wound repair, without reporting new clinical results.

In this narrative review, researchers outlined the role of T cells in the autoimmune pathogenesis of alopecia areata and highlighted ongoing research into therapeutic pathways, beyond current JAK inhibitors, aimed at developing new treatments for the disease.

In this study, researchers using a Treg-specific HuR-deficient mouse model found that the RNA-binding protein HuR is crucial for stabilizing Foxp3 mRNA, affecting Treg function and immune regulation, with HuR disruption leading to impaired Foxp3 expression and potential autoimmune dysfunction.

At the 21st Royan International Stem Cell Congress, researchers highlighted the growing integration in regenerative medicine, emphasizing advances in pluripotency, AI applications, and bioengineering for the development of accessible stem cell therapies.

This review discusses how circadian clocks may influence diverse physiological functions beyond their established role in daily timekeeping, but it reports no new experimental findings.

This review discusses the paracrine properties of cardiac stem cells and pericytes in regenerative medicine for ischaemic diseases and reports no new clinical results.

This review discusses the role of extracellular vesicles from specific skin cells in wound healing, emphasizing their potential in regenerative medicine and reporting no new experimental results.

This review discusses the distinction between platelet-rich plasma and stem cell-based therapies in regenerative medicine, highlighting their different roles and stressing the importance of honest representation by commercial and health entities.

This literature review suggests that hair cell loss in hearing loss is often secondary to preceding morphological and functional defects in hair cells, indicating that interventions should focus on hearing preservation before significant hair cell loss occurs.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

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 review addresses the role of skin-resident adult stem/progenitor cells in skin homeostasis, disease, and cancer development, and reports no new research results.

This review discusses the impact of calorie restriction on enhancing stem cell potency and regenerative abilities in mammalian tissues and reports no new experimental results.

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

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This review discusses the role of stem cell progeny as integral components of stem cell niches, offering feedback that may influence different stem cell systems' microenvironments, but it presents no new research findings.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

This article explores questions about dormant hematopoietic stem cells and suggests avenues for future research, but does not present new experimental results.

This study found that quiescent bulge stem cells, when prevented from contributing to hair follicle and epidermal regeneration, did not affect hair follicle growth or wound healing in the short term.

In this study, dermal papilla cells from rat vibrissae showed potential for treating CNS injuries by secreting neurotrophic factors and promoting neuronal differentiation more effectively than bone marrow mesenchymal stem cells.

This review examines the evolving understanding of lymphatic vessel development, emphasizing new cellular mechanisms and lineage diversity, while discussing experimental methods and identifying key knowledge gaps.

In this study, fractional laser treatment was observed to reverse age-related gene expression changes in skin and enhance dermal remodeling, further improved by multiple treatments.

This study found that stem cells can temporarily act as non-professional phagocytes during hair cycle regeneration by clearing apoptotic cells through a process requiring local lipids and retinoids for activation, providing insights into their dual role in maintaining tissue integrity.

This study discovered that the gene Tfap2b identifies a melanocyte stem cell population in zebrafish, essential for regenerating melanocytes with multi-fate potential into adult pigment cells.

This study found that the microRNA miR-22 is a key regulator of the hair cycle, influencing hair loss by promoting the transition from growth to rest phases and repressing keratinocyte differentiation.
