This study identifies a polygenic basis for atypical recurrent flank alopecia in Cesky Fousek dogs through genome-wide association analysis and gene expression profiling, highlighting several metabolic pathways involved in the condition.

This review discusses advances in using tissue engineering to improve the inductivity of dermal papilla cells for hair follicle restoration and reports no new clinical results.

This review discusses the role of dermal papilla cells in hair follicle formation and their potential use in cell therapy for hair loss, but reports no new research findings.

In this review, extensive analysis using conditional mutant mice revealed that androgen and Wnt signals play crucial roles in the development and function of male external genitalia and erectile tissue, while also exploring various regulatory factors involved in their pathogenesis.

In this retrospective review, the author discusses key discoveries in understanding androgen excess disorders like PCOS, focusing on genetic and molecular insights gained from 1965 to 2015.

This review discusses the heterogeneity and plasticity of epithelial stem cells in skin homeostasis, wound healing, and tumorigenesis, reporting no new results but emphasizing the need for further exploration of key regulatory mechanisms.

This review examined genetic factors in 46, XY differences/disorders of sex development and found that whole-exome sequencing is more effective than panel sequencing for molecular diagnosis. It identified regional genetic variation and emphasized next-generation sequencing's role in detecting variants related to gonadal and androgen-related genes.

This study explored the molecular communication between hair matrix cells and dermal papilla cells in cashmere goats, revealing key ligand-receptor pairs and signaling pathways that facilitate intercellular crosstalk and potentially influence hair growth mechanisms.

This study suggests that controlling light exposure can influence cashmere growth by triggering hair follicles to enter their active growth phase sooner, potentially involving the CSDC2 gene as a key regulator.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

This study identified distinct gene expression programs in keratinocytes responsible for forming hard scales and soft interscale epidermis in chickens, revealing conserved differentiation genes similar to those in human skin.

In this study, researchers observed that after mesenchymal cell division in mouse and chicken embryonic skin, elevated migration speed and persistence for 180 minutes contribute to mesenchymal dispersal and preferential recruitment to dermal condensates.

This review discusses trichotillomania, its diagnosis, prevalence, potential brain abnormalities, and current treatment options, and offers no new clinical findings.

Adjusting the medication tacrolimus resolved a boy's red nail beds after a stem cell transplant.

This article reviews the interaction between sex hormone pathways and morphogenesis-related signaling in epithelial organ development, using a chicken model to propose testable hypotheses, but reports no new clinical results.

In this study, researchers using the hair paradigm highlighted how periodic patterning and compartmentalization enable diverse regenerative behaviors, including region-specific renewal cycles and emergent properties like regenerative waves in organ populations.

This study found that mesenchymal cells in mouse and chicken embryonic skin undergo a process of migration driven by tissue tension and WNT secretion, influencing their dispersal and integration into dermal condensates.
