This review discusses insights from scar-free animal models and cellular factors in skin regeneration, suggesting potential strategies for developing scar-free treatments in clinical and cosmetic practices, but reports no new clinical results.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This report documents two cases of eruptive nevi occurring in the skin folds of children with Langerhans cell histiocytosis.

This review examines the challenges of hair follicle regeneration and outlines strategies for bioengineering human hair follicle models, without presenting new experimental results.

This article reviews the rare skin disorder ichthyosis with confetti, highlighting the potential for future therapies using revertant stem cells, and reports no new clinical results.

This study found that a 12-week supplementation with MePL, a solution of miliacin encapsulated within polar lipids, significantly reduced hair density in the telogen phase and improved scalp dryness and hair brightness in women with telogen effluvium.

This article reviews Elaine Fuchs’ groundbreaking discovery of adult skin stem cells' roles in homeostasis, wound repair, inflammation, and cancer, and reports no new results.

Acne is a common skin condition linked to diet, hormones, and genetics, and early treatment can prevent scarring.

In this study, researchers found that Hdac1 and Hdac2 are crucial for maintaining the quiescence and survival of dermal papilla cells in the hair follicle, regulating the hair cycle by controlling cell-cycle genes and Wnt signaling.

This study found that a two-month antioxidant treatment significantly improved hair growth in patients with alopecia areata by enhancing antioxidant defenses and correcting trace metal imbalances.

This study found that purified apple juice containing procyanidin B-2 promoted hair growth in both mouse models and human clinical trials for male pattern baldness.

In this study, canine hair follicle stem cells were shown to be multipotent, capable of differentiating into various cell types like adipocytes in vitro.

This article reviews the potential hair-protective effects of Onion and Aloe vera against damage from hair dyes but reports no new experimental results.

This observational study concluded that anti-Ku antibodies do not specifically indicate any systemic autoimmune disease or associated clinical phenotype.

This review outlines the various fibroblast subsets in the skin dermis, their origins, and their influence on epidermal stem cell behavior, highlighting the role of the local dermal niche in stem cell plasticity.

This study found that activation of the transcription factor Nrf2 in keratinocytes promotes wound healing in mice by expanding hair follicle stem cells, independent of changes in keratinocyte proliferation or migration.

This review discusses the evolving understanding of epithelial stem cells, noting how new models challenge old assumptions and suggesting multiple stem cell populations contribute differently to skin and hair follicle regeneration.

This study suggests that Botox injections may increase hair count and reduce hair loss in men with androgenetic alopecia, potentially through increased blood flow and oxygen to the scalp.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

This article reviews methods to enhance epithelial–mesenchymal interactions for hair follicle bioengineering but does not present new experimental results; it emphasizes optimizing combinations for successful regeneration.

This study found that using 3D dermal papilla spheroid models enhances extracellular matrix production and hair follicle marker expression, providing insights into hair follicle biology and potential for drug screening.

This study found multipotent progenitors in sweat ducts that become unipotent after sweat gland development, highlighting distinct regenerative capabilities in adult glandular skin stem cell populations.

This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

This study found that different stabilizing mutations in Aux/IAA proteins affect root hair development in Arabidopsis by disrupting the auxin response and suggest a model where the relative abundance of these proteins determines root hair initiation.

This research abstract provides no results, focusing on the equal contributions of the authors in the field of molecular, cellular, and developmental biology from Yale University.

In this study, researchers found that microRNAs and specific target genes, such as MiR-195 and genes like CHP1, SMAD2, FZD6, and SIAH1, play significant roles in regulating hair follicle initiation in cashmere goats.

Skin health and diseases are closely linked to metabolic processes.

This review highlights surprising similarities between hair follicles and antler units, suggesting that a comparative study of their biology could benefit understanding in both areas without presenting new empirical findings.
