This study estimates that young adults have about 230,000 tactile afferent fibers innervating their skin, with density varying by region and decreasing with age.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

Different types of stem cells and their environments are key to skin repair and maintenance.

This review discusses the roles of TGF-β family signaling in regulating normal and cancer stem cells and highlights the need for further research to develop potential cancer treatments; it reports no new results.

This study found that modulating BMP activity in transgenic mice affects the development and characteristics of several ectodermal organs, such as skin, hair, and claws, highlighting a stage-dependent influence on organogenesis.

This study found that macrophages play a crucial role in nerve regeneration by regulating Schwann cell dynamics and remyelination, with Gas6 identified as a key factor in this process.

This review discusses best practices for minimizing complications with dermal fillers and provides guidance based on expert consensus, yet it reports no new clinical results.

This review discusses the mechanisms and pathways of FGFR signalling and its roles in development, disorders, and therapeutic targeting, but reports no new clinical results.

This essay discusses the establishment, maintenance, and role of skin stem cells in tissue homeostasis, wound repair, and their relation to skin cancer, without reporting new experimental findings.

This study found that the protein MIM is crucial for maintaining cilia and Sonic hedgehog signaling in mesenchymal cells by counteracting Src-mediated phosphorylation of Cortactin, impacting hair follicle formation.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

This review discusses the impact of sleep cycles and circadian rhythms on nighttime exacerbation of atopic dermatitis in children and presents potential treatment options for related sleep disturbances, but reports no new clinical results.

This study found that cardiac fibroblasts significantly enhance the maturation of neonatal mouse and human embryonic stem cell-derived cardiomyocytes, suggesting a pivotal role in postnatal heart development and disease.

This review discusses the applications and research on fibroblast growth factors, including their use in wound healing, diabetes, and cancer, but it reports no new clinical results.

This study found that a mutation in the BMP12/GDF7 gene is associated with the Naked neck trait in chickens, reducing neck feathering due to altered signaling pathways.

Wnt/β-catenin signaling is crucial for cell fusion in placental development.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This review discusses the etio-pathogenetic factors in benign prostatic hyperplasia and their role in the development of lower urinary tract symptoms but reports no new research findings.

This study found that newborn mouse skin organoids can robustly grow hair in vivo, while adult organoids require specific interventions to restore their hair-forming ability.

This review covers the recent advances in understanding how Turing models may explain various morphogenetic processes, but it reports no new experimental findings.

This study suggests that the postnatal loss of hair follicle formation in wounds may be due to elevated Wnt/β-catenin activation in the dermis, affecting fibroblast function in mice.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.
