This review discusses how neuroendocrine regulation affects human hair follicles and suggests potential therapeutic targets, but it reports no new clinical results.

This study explored the complex developmental processes of human hair, emphasizing the intricate interactions required for hair follicle morphogenesis and its implications for drug incorporation and concentration interpretation, particularly in early childhood.

In this study, researchers found that knockdown of ABCA5 in primary human hair follicle keratinocytes disrupted cholesterol homeostasis and transportation, suggesting its potential role in hair growth disorders by affecting intracellular cholesterol compartmentalization and LXR-mediated transcriptional activity.

This review discusses various drugs and chemicals potentially causing hair loss, mechanisms involved, and suggests models for testing but reports no new clinical findings.

This research suggests that the barley protein RACB supports cell polarity functions rather than interfering with immunity, as it aids nucleus positioning during fungal attack rather than affecting early immune responses.

A specific gene mutation causes woolly hair and hair loss.

This study found that in scarring alopecia, stem cells are differentially localized, suggesting that both inner and outer root sheath stem cells, rather than just follicular bulge stem cells, are involved.

This study found that the S100A3 gene is exclusively expressed in hair follicle cells differentiating into hair shaft components in mice, suggesting its important role in hair formation.

Wnt-10b helps skin cells develop into hair-related structures.

This study observed dynamic changes in CD10 and CD34 expression in fetal and adult human hair follicles during embryogenesis and hair cycling.

This study found that vimentin expression in the hair follicles of Inner Mongolian Cashmere goats is highest during the growth stage and localized to the outer root sheath, suggesting a role in hair cycle regulation.

This study observed that decreased nucleolar organizing region protein synthesis in hair root cells is correlated with hair loss in humans.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

Using a transgenic pig model, this study demonstrated that LGR5 is a marker of hair follicle stem cells across different species, with important similarities and differences in gene expression and developmental processes.

This study found that apoptosis, along with proliferation, plays a crucial role in shaping and extending human hair follicles by coordinating the formation and differentiation of the hair canal.

This study found that the trichogenicity of cultured human outer root sheath follicular keratinocytes decreased with longer cultivation periods and was significantly influenced by the expression of the transcription factor FOXA2.

In this study, researchers found that dentin sialoprotein and phosphophoryn are present in rat and mouse hair follicles, suggesting these proteins may play a role in hair follicle development, similar to their role in dentin mineralization.

In this study, the PLP2 gene was found to promote secondary hair follicle development in Liaoning cashmere goats, with its expression negatively regulated by melatonin and potentially affecting follicle development via the BMP pathway.

This study found that peptidylarginine deiminase type III and trichohyalin are coincidentally expressed in the infant rat hair follicle, but trichohyalin deimination occurs after their expression during development.

In this study, Satura® Rosta remedy was found to significantly increase hair follicle size, hair root volume, and skin thickness in mice, potentially by prolonging the anagen phase, with notable hair regrowth observed in older mice with alopecia.

This study established a Krt24-CreERT2 mouse line targeting outer bulge hair follicle stem cells, finding these cells crucial for hair follicle development and repair, particularly following ionizing radiation exposure.

This study examined the cytodifferentiation stage of hair follicle development in cashmere goats, identifying nine cell populations and key regulatory pathways, including transcription factors and keratin genes, that may influence fiber quality and inform breeding strategies.

In a mouse model, this study found that intradermal keratin injection stimulated hair growth and suggested its potential use for treating hair loss by promoting hair regeneration.

This study found that genetic ablation of Tet genes in mice led to changes in hair structure and keratin gene expression, indicating a role for Tet-mediated 5hmC DNA oxidation in hair follicle development and cycling.

In this study, Sox13 was identified as a novel marker for early hair follicle development and differentiation in mice, though it appears to be dispensable for overall epidermal and adnexal development.

This study found that certain growth media combinations influence the development of Arabidopsis thaliana root hairs, identifying specific conditions that promote the growth of the longest root hairs.

This study demonstrated that injecting reconstructed dermal papilla-like tissues in mice led to new hair growth, suggesting potential future applications in hair transplantation and baldness treatment.

This study found that topical application of Korean ginseng berry promoted hair follicle development in mice, with a lower dose proving more effective than a higher dose.

This study observed that glycine inhibited root growth and stimulated root hair development in habanero pepper seedlings, with ethylene signaling suggested to mediate these effects.
