Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

This study found that overexpression of miR-214 in keratinocytes inhibits hair follicle development and cycling by targeting β-catenin in the Wnt signaling pathway.

In this study, researchers developed a method to differentiate human iPSCs into cells that can generate all lineages of hair follicles, potentially aiding treatments for hair loss and skin disorders.

This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This review discusses the potential markers for identifying and studying stem cells in the epidermis and hair follicles, highlighting their role in understanding skin disease pathogenesis and expanding therapeutic options, but reports no new findings.

This review discusses recent findings on hair follicle morphogenesis and regeneration, focusing on molecular signals and stem cells, and suggests that understanding these processes may aid in developing new strategies for wound healing.

In this study, mouse sweat gland development relied on a regulatory sequence initiated by Wnt/β-catenin signaling, and disruptions in Wnt, Eda, or Shh pathways led to distinct developmental failures.

This article reviews fetal scalp hair formation and related disorders but reports no new research results.

This article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.

This review explains how recent understanding of Wnt signaling regulation in hair follicles could potentially be used to enhance hair growth, but it reports no new empirical results.

This article reviews the genetic basis, diagnostic approaches, and treatment options for nude severe combined immunodeficiency, but does not present any new research findings.

This study indicates that the Sp6 gene is crucial for the development of skin, teeth, limbs, and lungs in mice, possibly through regulating apoptosis.

This study found that IGF-1 likely plays a crucial role in regulating hair growth and alopecia, with balding scalp follicles secreting less IGF-1 than nonbalding counterparts.

This study found that the DNA methylation status of skin samples from cashmere goats was higher during the telogen stage compared to the anagen stage, identifying genes potentially important for hair follicle development and growth.

This review discusses the strategies and progress in developing bioengineered organ replacement therapies but reports no new clinical results, highlighting the potential for future regenerative solutions.

This study generated FGF5-knockout Dorper sheep using the CRISPR/Cas9 system, resulting in significantly increased fine-wool and active hair-follicle density, and explored downstream signaling pathways for potential applications in androgen alopecia treatment.

This study found that ILK deficiency disrupts hair follicle development by impairing cell polarity and laminin-511 assembly, but these defects can be partially reversed with exogenous laminin-511.

This study found a novel PAX9 gene mutation that may cause tooth agenesis and trichodysplasia in a studied family.

This study found that Hoxc13-/- rabbits exhibit complete hair loss on the head and dorsum, providing a potential model for understanding human ECTD-9 and related dermatological conditions.

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 reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

This study found that activin B promotes the initiation and development of hair follicles in both cultured and neonatal mouse skin models.

This study used single-cell ATAC sequencing to map chromatin accessibility in developing mouse hair follicles, offering insights into the transcriptional regulation and epigenetic mechanisms underlying hair follicle development.

This study found that NNAT is localized in both undifferentiated and differentiated cells across various rat tissues and has cell-specific intracellular localization, suggesting distinct functional roles.

This review discusses platelet-rich plasma therapy for nonscarring alopecia and reports no new clinical results; the author recommends more large-scale controlled studies, particularly for scarring alopecia and symptom control.

This study identified a small population of PAX3+/CD34+ cells in human foreskin tissue that may serve as transition cells between melanocyte stem cells and hair follicle stem cells, characterized by specific marker expressions.

Fetal death was caused by umbilical cord stricture with hair growth in the Wharton jelly.

This article reviews various hair growth and hair loss treatments, noting limited new developments since FDA-approved drugs but highlights recent cosmetic surgery and potential cell-based therapies; it reports no original findings.

In this mouse study, the absence of the Ascl4 gene did not affect the development of hair follicles, teeth, or mammary glands, suggesting it is non-essential for these processes.
