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 the potential use of cultured primary fetal cells from a single organ donation to produce therapeutic products, emphasizing the need for process consistency and safety verification, but reports no clinical results.

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

This study found that Wnt/β‐catenin signaling influences the hair follicle regeneration process by prompting quiescent stem cells to enter the cell cycle and is necessary for maintaining the stem cell pool.

This review discusses the generation of germ cell-like cells from skin-derived stem cells and reports no new results; the potential for these cells to produce viable progeny remains unclear.

This article reviews the roles and mechanisms of stem and progenitor cell migration in adult organs for tissue homeostasis and regenerative medicine, but reports no 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.

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 study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.

This article reviews the role of KLF4, a transcription factor, in various cellular processes and its dual function as a tumor suppressor or oncogene depending on the context, but presents no new experimental results.

This review explores the potential role of caveolin-1 in cicatricial alopecia, particularly frontal fibrosing alopecia, and discusses possibilities for targeted therapies without providing new research results.

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.

In this research, the authors identify coordinated mechanical forces as crucial for hair follicle development in mammals, with contractile, proliferative, and proteolytic activities facilitating the formation and sectioning of epithelial structures crucial for forming a functional tissue.

This review summarizes discussions from a 2010 stem cell biology meeting, covering the origin, behavior, and therapeutic potential of pluripotent and multipotent stem cells, without reporting new experimental findings.

This study found that disrupted cholesterol homeostasis impairs hair regrowth in individuals with primary cicatricial alopecia by damaging hair follicle stem cells, highlighting the importance of cholesterol in maintaining stem cell function and hair follicle integrity.

This review highlights various methods of stem cell communication that reflect the unique organization and function of different tissues and reports no new results.

In this study, fibronectin coating on a low-adhesive substratum increased cell aggregation, growth, and motility, enhancing the formation of hair follicle dermal papilla spheroids.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

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

This study found that the circadian clock regulates the activation state of murine epidermal stem cells, affecting tissue homeostasis and susceptibility to tumorigenesis when disrupted.

This review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This review discusses epidermal stem cell diversity, revealing previously unrecognized differences in stem cell populations, but reports no new experimental results; it highlights the need for further exploration of stem cell interactions and quiescence.

This review discusses the distinct roles and surprising developmental flexibility of multiple somatic stem cell types in tissue maintenance and repair, reporting no new results but highlighting emerging questions about their regulation and origins.

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.

This study found that applying dexamethasone to mice induced catagen-like follicle changes significantly earlier and more consistently than a vehicle, such changes being useful for studying hair follicle regression.

This review discusses recent advances in hair follicle biology, regeneration, and tissue engineering, highlighting emerging therapeutic opportunities, and reports no new experimental results.

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

This study found that in androgenetic alopecia, reduced stem cell factor production by dermal papilla cells may lead to decreased pigmentation in hair follicles.
