This review discusses historical and recent advances in understanding the embryonic organizer's role in patterning during development, including molecular pathways and future research challenges, but reports no new experimental data.

This study concluded that hair-derived stem cells from older donors may offer a promising alternative for autologous corneal endothelial replacement, potentially benefitting patients of various age groups.

This study found that maternal melatonin supplementation improved fur quality in Rex rabbit offspring by increasing hair follicle density and altering melatonin receptor gene expression in several organs.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.

This review examines the challenges of hair follicle regeneration and outlines strategies for bioengineering human hair follicle models, without presenting new experimental results.

This study reported that exogenous R-spondin-1 can restore hair follicle neogenesis in adult mouse cells, highlighting differences in gene expression and signaling pathways between fetal and adult dermal papilla cells.

This study demonstrates that Tp63-expressing epithelial stem cells from non-skin tissues can respond to skin morphogenetic signals and contribute to the formation of hair follicles, sebaceous glands, and epidermis.

This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

This review discusses the role of extracellular vesicles from specific skin cells in wound healing, emphasizing their potential in regenerative medicine and reporting no new experimental results.

This abstract explains that androgenetic alopecia, a common hair loss disorder influenced by genetics and hormones like dihydrotestosterone, has FDA-approved treatments including minoxidil, finasteride, and photolaser therapy, but its genetic basis and susceptibility to environmental factors remain complex.

This study found that post-finasteride syndrome patients showed a tissue-specific methylation pattern of the SRD5A2 promoter in cerebrospinal fluid, potentially affecting neuroactive steroid levels and related behavioral symptoms.

In this controlled study on hair transplantation, using autologous plasma as a graft holding solution resulted in better hair follicle cell survival, hair count, and density compared to Ringer's lactate, suggesting plasma's potential to enhance hair graft outcomes.

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 study describes three new cases of MCOPS6 with BMP4 variants, noting expanded phenotypic variability but no clinically apparent microphthalmia in these individuals, which is commonly reported in the disorder.

This article reviews how biomaterials and stem cells could advance regenerative medicine but does not report new results, emphasizing the potential of combining novel biomaterials with stem cells for effective therapies.

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 review highlights surprising similarities between hair follicles and antler units, suggesting that a comparative study of their biology could benefit understanding in both areas without presenting new empirical findings.

Mouse Scube3 affects teeth, tongue, vibrissae, and eye development, but not facial structure or limb growth.

This study found that in chimaeric mice models, the pigment distribution and pattern were influenced by the sash genotype, demonstrating the melanocyte-autonomous nature of the beige and leaden loci.

This commentary reviews potential dietary and mineral influences on androgenetic alopecia and suggests considering a diet low in cholesterol and glycaemic index with improved glucose control and magnesium fortification, without new clinical results.

In this study, bromocriptine's inhibition of prolactin promoted secondary follicle development during anagen in cashmere goats, likely via changes in specific gene expressions, despite not affecting fiber characteristics or primary follicle activity.

This study found that specific polymorphisms in the VDR gene, Taq1, and Cdx1, were significantly associated with increased risk of chronic telogen effluvium in women.
