This review explores embryonic epidermal development and discusses key molecular regulators and roles of the sub-epidermal mesenchyme, but reports no new experimental results.

This article reviews the role of stem cells in tissue development, tumor formation, and organoid generation, and highlights the potential of epigenetic regulation in advancing regenerative medicine and cancer treatment, without presenting new experimental results.

This review discusses the dual role of tissue-resident memory T cells in providing immune protection against infections and cancer and contributing to autoimmune skin disease pathology, without presenting new experimental results.

This review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.

This review examines the roles of macrophages and Langerhans cells in skin homeostasis and suggests that understanding these functions can aid in developing therapies for skin and hair regeneration, but it reports no new research findings.

This study analyzed skin from 538 knockout mouse mutants and identified 50 with epidermal phenotypes, providing valuable insights into genetic conditions and systemic effects related to skin abnormalities.

This review examines the role of regulatory T cells in skin immune disorders, highlighting their unique functions in conditions like scleroderma, alopecia areata, and psoriasis, without reporting new clinical results.

This study found that selective deletion of Ctip2 in epidermal keratinocytes in adult mice leads to atopic dermatitis-like inflammation and suggests Ctip2 plays a crucial role in skin barrier maintenance and inflammatory regulation.

This review discusses the regulation and dynamics of the Wnt/β-catenin signaling pathway in development, pluripotency, and cancer, highlighting potential mechanisms and future research directions, but reports no new results.

This article reviews sebaceous immunobiology and highlights the complex role of sebaceous glands and sebocytes in skin barrier function and inflammation, particularly in acne pathogenesis, but reports no new results.

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 review discusses historical and recent advances in understanding the embryonic organizer's role in patterning during development, including molecular pathways and future research challenges, but reports no new experimental data.

In this study, re-activating SOX9 in adult epidermal stem cells led to a fate switch towards hair follicle stem cell identity, with altered chromatin dynamics and oncogenic activation, contributing insights into developmental processes and cancer pathways.

This study found that androgens downregulate BMP2 in dermal papilla cells, inhibiting hair follicle stem cell differentiation, while BMP2 addition may restore hair lineage differentiation through the Wnt/β-catenin pathway.

This study found that mutations in the TULP3 gene are associated with progressive degeneration of the liver, kidney, and heart in adults, highlighting the importance of early detection and management.

This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.

Skin aging reflects overall body aging and can indicate internal health conditions.

This study revealed that during avian skin development, complex tissue architecture results from specific cellular flows and mechanical processes that guide feather bud protrusion and elongation, with distinct differences noted in scale development, where rigidity restricts such transformations.

This study investigated the possible role of neutrophil extracellular traps in contributing to fibrosis in stenotic Crohn's disease.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

This study identified a set of wound-induced genes in planarians that play a role in regeneration initiation, with some genes specifically activating within regenerative cells called neoblasts.

This study found that quiescence in hair follicle stem cells acts as a tumor suppression mechanism for cutaneous squamous cell carcinoma, with Pten activity necessary to maintain this state.

This review explores how sex differences influence the pathophysiology, incidence, and treatment outcomes of ischaemic heart disease, and emphasizes the need for more sex-specific research.

This study found that the CXXC5 protein is overexpressed in diabetic foot ulcer tissues, suppressing wound healing, and that the small molecule KY19334 accelerated healing in diabetic mice by activating the Wnt/β-catenin pathway.

In this study, full-thickness wounding on Lanyu pigs led to scar formation and disrupted cell markers, while partial-thickness wounding allowed limited regeneration of rete ridges and papillary dermis.
