In this study, the researchers developed an in vitro model that maintains human hair follicles to grow at in vivo rates and observed that factors like EGF and IGF-I influence hair follicle growth and catagen entry.

This article discusses the challenges in hair follicle pigmentation research compared to epidermal melanocytes and highlights the limitations of relying on mouse models, but reports no new experimental findings.

This review discusses the functions and potential therapeutic targeting of TRP ion channels in the skin, noting their involvement in both physiological processes and various pathological conditions, but reports no new experimental results.

This essay discusses the establishment, maintenance, and role of skin stem cells in tissue homeostasis, wound repair, and their relation to skin cancer, without reporting new experimental findings.

This review explores the hormonal regulation of hair growth and changes with season, age, and sexual development, and calls for improved treatments for hair disorders.

This review summarizes recent multidisciplinary advances in sebaceous gland research and highlights potential novel therapeutic strategies for skin diseases, but it reports no new clinical results.

This study found that continuous expression of epidermal growth factor in transgenic mice prevented hair follicles from entering the catagen phase, implicating EGF as a crucial regulator in hair cycle progression.

This review examines the skin exposome, including solar exposure, air pollution, hormones, nutrition, and psychological factors, but reports no new clinical results.

This study found that hair depigmentation in mice and humans can be a dynamic indicator of KIT inhibition by the drug SU11248, correlating with treatment periods.

This chapter reviews the role of androgen receptors in mediating the actions of androgens in specific tissues and provides no new experimental findings.

This article reviews key questions in skin biology, particularly the mechanisms of hair follicle patterning and the role of stem cells in the epidermis, reporting no new results.

This review discusses the basic biology of apoptosis and its relevance to skin diseases, without presenting new research findings.

Hair follicles grow hair and release it through the skin.

This study found that hair follicle homeostasis in mice requires vitamin D receptor expression in keratinocytes, independent of its ligand activation.

This review discusses the paracrine function of mesenchymal stem cells in tissue regeneration and repair, focusing on secreted bioactive substances and their role under different microenvironments; it reports no new clinical results.

This study found that thyroid hormones T3 and T4 enhance keratin 15 promoter activity and stimulate CD200 expression in epithelial stem cells from human scalp hair follicles, affecting their growth and differentiation.

This source reports that scalp cooling is currently the only safe and FDA-cleared method to potentially reduce chemotherapy-induced hair loss, with about a 50% chance of maintaining sufficient hair to avoid needing a wig.

This study explored the regenerative abilities of the African spiny mouse's skin, revealing more robust wound-induced hair follicle neogenesis compared to laboratory mice and highlighting unique features of its hair and wound response.

This study suggests that the action of minoxidil in stimulating hair growth likely occurs at the follicular dermal papilla, though it does not induce new follicle formation.

This study found significant changes in gene expression related to skin structure and signaling pathways in AEC syndrome skin, offering new insights into the syndrome's molecular underpinnings.
