In this study, forced expression of the transcription factor cDermo-1 in chicken dermis led to the formation of ectopic feather buds and enhanced feather growth, demonstrating its role in initiating skin appendage development.

This study found that crosstalk between fibroblasts and endothelial cells significantly contributes to hypertrophic scar formation by enhancing fibroblast activity through cytokine secretion, with pathway analyses suggesting molecular targets for potential therapeutic interventions.

This review discusses the development of human skin with a focus on desmosomes, noting the challenges of translating animal model findings to humans due to species differences and limited human sample access.

This study found that coffee berry extract demonstrated anti-aging properties in skin and hair cells, showing significant anti-collagenase activity and stimulating hair-related gene expression, suggesting its potential for use in cosmeceuticals.

In this study, researchers propose that different vertebrate skin appendages, such as hair, feathers, and scales, evolved in parallel from a shared ancestral cell structure associated with teeth, dating back approximately 420 million years ago.

This review discusses the role of heparan sulfate proteoglycans in regulating stem cell fate and highlights their potential as targets for addressing hair loss, without reporting new clinical results.

This study found that incorporating Canavalia ensiformis lectin into alginate and carboxymethylcellulose films enhanced angiogenic factor expression, suggesting these biopolymer films could be an effective alternative for wound treatment.

This study presented a case where a 23-year-old woman with alopecia induced by hyaluronic acid injections experienced full hair regrowth using a combination of Concentrated Growth Factor, microneedling, and minoxidil, and also reviewed literature noting variable success rates with other treatments.

In this study, researchers developed a multilayered gel bead culture model using a microgel-spotting device, successfully mimicking the early development of skin appendages and supporting in vitro hair follicle regeneration with structures resembling native hair follicles.

This study found that in vitro, beard dermal papilla cells stimulated keratinocyte proliferation via androgen-dependent growth factors, while androgenetic alopecia cells released TGF-β1, inhibiting keratinocyte growth.

mIGF-1 in skin cells speeds up wound healing and hair growth in mice without harmful effects.

This study found that lncRNA H19 may regulate CTGF expression in KGN cells by acting as a "sponge" for miR-19b, potentially influencing polycystic ovary syndrome development.

In this study, PEG and keratin scaffolds selectively influenced protein release rates based on charge and size, suggesting their potential for targeted delivery of protein therapeutics.

This study suggests that Silybum marianum flower extract may promote hair growth and reduce hair loss by increasing proliferation and VEGF production in dermal papilla cells and suppressing cell senescence.

This study found that dermal papilla cells from beard and axillary hair follicles can produce androgen-dependent factors that stimulate proliferation in adjacent follicular epithelial cells under testosterone influence.

This study observed that testosterone metabolism and androgen receptor localization differ significantly across body sites, with beard hair follicles showing distinct characteristics compared to occipital scalp hair follicles.

This study found that Eucommia ulmoides bark extract shows potential antioxidant and hair follicle-support properties in vitro and in vivo, but further validation is needed to confirm these effects.

This study found that a microneedle system delivering VEGF and Ritlecitinib improved hair regeneration in mice with androgenetic alopecia, showing faster anagen onset and better hair quality compared to minoxidil.

Reducing CD8+ T cell growth can stabilize alopecia areata.

This article discusses the minimal research on hair growth physiology and highlights Dr. Masumi Inaba's contributions to understanding androgenetic alopecia, but reports no new experimental results.

This review explains various types of hair loss and unwanted hair growth in women, emphasizing the complexity of treatment due to their diverse causes, but it reports no new clinical results.

Hair loss in androgenetic alopecia is caused by genetic factors and androgen excess, and can be treated with combined therapies.

The authors concluded that dermal white adipose tissue, influenced by factors like light irradiation, plays a significant role in modulating hair follicle cycles and could be targeted for hair growth treatments.

This study explores the complexities of interpreting single drug exposure in hair, emphasizing factors like drug distribution variability and suggests methods to validate single exposure findings in forensic cases.

This review discusses the most popular non-surgical cosmetic procedures for men and highlights the importance of considering sex-specific factors for optimal treatment, but reports no new clinical results.

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 study reported that in male subjects with androgenetic alopecia, there is greater uncertainty in hair growth duration, with regulatory factors in the dermal papilla significantly affecting outcomes.

This article discusses the development of skin patterns during embryogenesis and postnatal life, linking them to genetic, environmental, and mathematical factors, but presents no new empirical findings.

Testosterone was found to inhibit hair follicle epithelial cell proliferation in adult stumptailed macaques only when dermal papilla cells from bald scalps were present, and this effect was reversed by the antiandrogen RU 58841.

This review discusses the role of flavonoids and Nod factors in the symbiosis between legumes and rhizobia and reports no new results; the authors argue this knowledge could enhance sustainable agriculture.
