In this study, researchers observed that mechanosensory neurons initially develop similar morphologies across different skin regions but diverge post-natally, adapting to the type of skin they innervate, with bone morphogenetic protein signaling crucial for forming Meissner corpuscles in glabrous skin.

This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

This study observed that both prenatal androgen exposure and postnatal early-life environment influence the development of PCOS-like phenotypes and changes in the gut microbiota in prenatally androgenized offspring.

This study found that FZD2 is crucial for hair follicle formation and postnatal growth in mice and has a novel role in regulating early epidermal development, including stratification and cornification.

This study found that inducing Atoh1 expression in transgenic mice is sufficient to generate new Merkel cells in the epidermis, with variations by skin location, developmental age, and hair cycle stage.

This study observed that low-dose intrauterine exposure to finasteride alters postnatal prostate development in male and female Mongolian gerbils, showing sex-specific differences in receptor expression and tissue changes.

In this study, researchers used conditional mouse models to show that inactivation of the Alx4 gene in specific cell lineages leads to craniofacial and limb defects without affecting postnatal survival, providing insights into Alx4's role in development and disease.

In this study, researchers found that Dicer, but not Tarbp2, plays a crucial role in regulating the growth phase of hair follicles in post-natal mice.

This research reports that paternal finasteride treatment in male rats may negatively impact liver function in their male offspring, as observed through altered expression patterns of ERα and PCNA in liver tissue across different developmental stages.

This study found that Bnip3L and caspase-12 were differentially expressed during the first catagen stage of mouse hair follicle development under normal physiological conditions.

In this study, transgenic mice with active BMPR1A signaling in the epidermis had impaired hair follicle morphogenesis and showed age-related hair loss, implicating BMP signaling in hair follicle development and homeostasis.

This review discusses mesenchymal–epithelial interactions in hair follicle development and cycling, highlighting recent insights without reporting new experimental results.

This study found that early postnatal androgen activity affects the long-term expression of hormone receptors differently in female Wistar rats, influencing neural system programming during development.

This review discusses the roles of key developmental signaling pathways in mammalian skin repair compared to skin development, and suggests these insights could lead to better wound healing therapies, but it reports no new findings.

Pigs are a good model for studying human hair growth and disorders.

This study found that mitochondrial oxidative phosphorylation in epithelial cells is necessary for proper enamel formation and odontoblast differentiation in developing incisor teeth in K320E-Twinkle Epi mice.

iNKT cells help develop and maintain healthy skin in young mice.

This study identified key genes involved in hair follicle development in Merino sheep, offering insights for improving wool production and providing a basis for future breeding programs.

This study found that mutant mice with the we/we wal/wal genotype exhibit significant defects in hair shaft structure and epidermis stratification, correlating with postnatal alopecia symptoms.

This study observed that in frizzled 6 null mice, initially uncorrelated hair follicle orientations develop into highly ordered patterns over time, suggesting possible mechanisms for biological structure patterning.

This review discusses the critical role of BMP signaling in the development and regulation of skin and hair follicles and notes that further research could aid therapeutic advances; it presents no new clinical results.

This study found that the PP2A-B55α regulatory subunit is crucial for ectodermal development in mice, with knockout embryos displaying severe neural and epidermal defects and failing to survive to birth.

This study suggests that Sox13, although dispensable for epidermal development, serves as a marker for early hair follicle development in Sox13-LacZ knock-in mice.

In this study, epidermal growth factor expression significantly correlated with the development of secondary hair follicles in Jining Gray goats until two months of age.

This review provides an overview of Hox genes, focusing on their evolutionary history, genomic organization, and roles in development, but reports no new study results.

This study reports that the differential expression patterns of three retinaldehyde dehydrogenases suggest a regulated need for retinoic acid synthesis in various organs during late mouse organogenesis.

Sox13 is a new marker for early hair follicle development and differentiation.

This review discusses melanocyte development, emphasizing the plasticity of melanoblasts and the role of both intrinsic and extracellular signals in their differentiation and migration, with no new clinical results reported.

This study found that LEF1/TCF3 is necessary but not sufficient for TOPGAL activation in hair follicle development, indicating complex regulation in the skin.

This study observed that hair follicle innervation in C57BL/6 mice occurs in sequential stages that closely correlate with the development of hair follicles, indicating an interdependent relationship between neuronal and epithelial morphogenesis.
