This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.

This study found that while a tip-focused calcium gradient influences localized growth in root hairs and pollen tubes, it is not the primary determinant of growth direction in root hairs of Arabidopsis thaliana.

This review summarizes recent advances in Treg cell biology, focusing on Foxp3's role in immune regulation and therapeutic reprogramming for immune dysregulatory disorders, but reports no new clinical results.

This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.

This review discusses the effects of estrogens on skin aging and highlights the potential benefits of estrogen replacement therapy and selective estrogen receptor modulators for improving skin health in postmenopausal women, but reports no new clinical findings.

This study found that SARS-CoV-2 hijacks the host factor IGF2BP1 to stabilize its RNA and enhance translation, and identified Cepharanthine and Trifluoperazine as potential treatments against the virus.

This review discusses the molecular mechanisms of androgens and androgen receptors in skin disorders, particularly androgenetic alopecia, and reports no new clinical results; it highlights potential areas for future treatment development.

In this study, thymosin beta4 was found to stimulate hair growth in normal rats and mice by affecting key processes in the hair follicle cycle, such as stem cell migration and extracellular matrix remodeling.

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 role of Wnt/β‐catenin signaling in stem and cancer stem cell maintenance and its involvement in the development and regeneration of various organs, but reports no new experimental results.

This review discusses the differences in wound healing between fetal and adult skin, highlighting the potential to uncover genes for scarless repair that could improve adult wound healing.

This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.

This review examines the neuroendocrine mechanisms underlying seasonal changes in mammals and highlights areas needing further research, reporting no new experimental results.

This study found that downregulation of EGF and KGF signaling is necessary for hair follicle initiation in placodes, revealing a new role for KGF in hair follicle formation in mice.

This review examines PAK4 signaling pathways in prostate cancer, Parkinson's disease, and melanogenesis, focusing on the potential role of the PAK4-CREB axis, without reporting new clinical results.

This review discusses circadian clock regulation in stem cells and its role in processes like neurogenesis, but reports no new results; the authors emphasize its significance in stem cell function across various tissues.

This study found that ectopic expression of Whn in transgenic mice caused impaired differentiation in epidermis and hair follicles, with hair growth defects and severe urinary tract issues leading to hydronephrosis.

This study introduced a novel in vitro assay for tracking melanosome transfer between melanocytes and keratinocytes, facilitating the quantification of melanin transfer and supporting the role of filopodia as a conduit.
