In this review, recent innovations in hair transplantation, such as AI-assisted graft selection, robotic systems, stem cell therapy, and advanced drug delivery techniques, are reported to enhance hair density and thickness for more natural results and higher patient satisfaction by addressing limitations of traditional methods.

In this case study, researchers reported the first documented instance of malignant transformation of congenital triangular alopecia into basal cell carcinoma in a 48-year-old woman, underscoring the importance of assessing long-standing alopecic areas for malignancy.

In this study using live mice, researchers observed that during hair follicle regression, apoptosis in basal cells may propagate by triggering neighboring cells, potentially regulated by a gradient of pro-survival signals from stem cells, and proposed a testable mechanism to further explore this process.

This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

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

This research discusses a novel imaging approach in live mice to study stem cell and niche interactions in tissue homeostasis and reports no new results.

This review discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

This review discusses the latest understanding of androgenetic alopecia, including stem cell niches in hair follicles, and highlights emerging treatments like growth factors and platelet-rich plasma without new clinical findings.

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.

This study found that epidermal stem cells in nonglabrous skin are connected to the distal end of the arrector pili muscle, which may play a role in epidermal renewal and wound healing.

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 review discusses the advancements in intraoperative stem cell therapies and highlights their potential to improve hair regrowth, but it reports no new clinical results.

This review discusses the enhanced understanding of how stem cell niches respond adaptively to systemic signals, aging, and local perturbations, but reports no new research findings.

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 in psoriasis patients, the K17 protein probably functions as an autoantigen, with the HLA-Cw*06:02 risk genotype strongly linked to the T cell response size.

This review examines the interaction between hedgehog and Wnt/β-catenin signalling in hair follicles and basal cell carcinoma, linking Hh pathway inhibition to both tumor regression and alopecia.

This study observed that disrupting the Pnkp gene in adult mice resulted in a premature aging-like phenotype, suggesting PNKP's vital role in maintaining normal growth and survival of certain progenitor cell populations.

This study found that the repressive histone mark H2AK119ub links inhibitory FGF signals with the quiescent state in hair follicle stem cells, revealing a signaling-epigenetic axis crucial for maintaining stem cell quiescence and tissue homeostasis.

Different types of stem cells and their environments are key to skin repair and maintenance.

This article reviews the role of perifollicular regulatory T cells in maintaining hair follicle integrity in the context of hidradenitis suppurativa and calls attention to inflammatory mechanisms without reporting new clinical results.

This study found that mammary resident macrophages play a key role in mammary tissue development by influencing cell division and maintaining mammary stem cell activity through the TNF-α-Cdk1/Cyclin B1 signaling pathway, highlighting their importance in the mammary stem cell niche.

In this study, researchers suggest that hair follicle miniaturization in conditions like androgenetic alopecia may result from impaired conversion of quiescent stem cells to progenitor cells, influenced by the follicular niche, its collagen network, and various mechanical constraints.

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 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 review discusses three aspects of cell fate specification across Metazoa and reports no new experimental results, highlighting the formation of nematode equivalence groups, evolution of echinoderm skeletogenic mesoderm, and adult cell fate regulation.

This study established a new in vitro culture system that supports the growth and dynamic self-organization of hair follicle stem cells and their progeny, promoting a stable population equilibrium.

This review discusses how recent advances in live imaging have revealed the dynamic and adaptable nature of stem cells during various biological processes, and reports no clinical results.

This study identified three main ethical concerns regarding stem cell use from an Islamic perspective in Malaysia, focusing on embryonic stem cells, aesthetic applications, and therapeutic medicine.

This study found that telomere shortening disrupts BMP/pSmad/P63 signaling, leading to skin atrophy via Follistatin up-regulation, and suggests potential therapeutic targets.

This article reviews the potential advantages of secretome derivatives from human uterine cervical stem cells in MSC therapy and notes the need for regulatory standards to ensure safety and efficacy.
