The study found that reducing testosterone in male mice through castration or androgen antagonism significantly accelerated wound healing by decreasing inflammation, suggesting a potential therapeutic target for impaired healing in elderly men.

This study observed that vitamin D receptor knockout mice exhibit impaired epidermal differentiation and progressive hair loss, suggesting the importance of the vitamin D receptor in normal skin and hair follicle development.

This study found that dermal papilla cells in human hair follicles exhibit stronger expression of VEGF mRNA and protein compared to other follicular cells, suggesting their key role in angiogenic processes related to hair growth.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

In this study, specific versican expression was observed in the anagen phase of human hair follicles, suggesting its importance in maintaining normal hair growth.

This study suggests that the paradoxical effects of androgens on hair growth are due to differential gene expression in hair follicles, possibly established during embryogenesis.

This review discusses the complex interaction between androgens and hair follicle biology, highlighting the need for a better understanding to improve hirsutism treatments, but reports no new results.

This study found that macrophage extracellular vesicles enriched with Wnt proteins significantly promoted hair follicle growth in mice and increased hair shaft size in human hair follicles, suggesting potential clinical use for treating hair loss.

This study reported significant upregulation and release of S100A4 in psoriatic skin, which may actively contribute to psoriasis pathogenesis.

This review examines the differentiation potential of epithelial cells from various sources in hair follicle formation, concluding that complex interactions are required for hair-specific characteristics, which were achieved in vivo but not in vitro.

In this study, researchers detailed how hair follicles regenerate after microsurgical amputation, observing a wound reaction involving dynamic dermal-epidermal interactions and changes in extracellular matrix components.

This study concluded that using adipose tissue-derived stromal vascular fraction significantly improved acne scars by increasing collagen content and skin thickness compared to nanofat alone.

This study established a 3D in vitro culture system of canine keratinocyte organoids to study epidermal function and address skin disorders in dogs, though additional growth factors are needed for hair follicle development.

This study found that intradermal administration of adipose-derived stem cell–conditioned medium significantly increased hair density and dermal thickness, suggesting potential regenerative effects on both hair follicles and the interfollicular scalp in patients with alopecia.

This article reviews the molecular interactions involved in hair follicle cycling and highlights the role of dermal papilla cells, but it presents no new research findings.

This study found that placental growth factor (PlGF) enhanced hair shaft elongation and accelerated hair follicle growth, suggesting its potential as a therapeutic target for alopecia.

This study found that 3% peppermint oil significantly enhanced hair growth in C57BL/6 mice, showing increased dermal thickness, follicle number, and follicle depth compared to other treatments.

In this study, Astragaloside IV was found to inhibit apoptosis-related pathways in hair follicles of mice, suggesting it may serve as an alternative therapy for hair loss.

In this study, hair follicle germs containing vascular endothelial cells showed improved hair regeneration and morphogenesis-related gene expression in mice, suggesting a promising strategy for hair regenerative medicine.
