This article reviews the development and use of induced pluripotent stem cell models and artificial organoids for studying neurodevelopmental disorders, but it reports no new clinical findings.

This review discusses current stem cell technologies, their potential therapeutic uses, and imaging techniques for tracking transplanted cells, without reporting new experimental results.

This study found that overexpression of R-spondin 3 in a mice model impaired hair morphogenesis and regeneration by reducing hair matrix progenitor cell proliferation, thus disrupting the Wnt pathway's regulation of stem cells.

This study observed that gerbils exhibit a different wound healing mechanism compared to mice, with lower TGF-B1 expression and distinct tissue responses, yet achieve similar healing outcomes.

This study found that the Foxn1(-/-) nude phenotype significantly influences epithelial progeny in skin, with notable changes in stem cell niches not achievable in other models.

This chapter reviews skin components, wound healing mechanisms, and the potential of biomaterials to enhance skin repair and regeneration, without offering new experimental results.

This review discusses molecular signaling pathways and nutritional factors influencing feather growth and regeneration in poultry and offers no new results; the authors suggest these insights may guide strategies for producing superior plumage.

This study found that all-trans retinoic acid (ATRA) negatively affects hair growth by reducing goat dermal papilla cell viability and growth factor expression.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

This paper provides a comprehensive review of melanocytes' roles in skin biology, focusing on their pigmentation and immune functions, and suggests potential research opportunities for preventing and treating skin disorders.

This study observed that in chicken skin, large-scale differences in gene expression between feathered and scaly skin are controlled by enhancer-driven uniform expression, while small-scale differences within individual feathers are associated with chromatin looping.

This article reviews the occurrence of ectopic sebaceous glands in hair follicle matrix during hair embryogenesis and reports no new clinical results, indicating unknown pathogenesis and clinical implications.

This review discusses the molecular pathology of progeroid syndromes and reports no new results; the authors emphasize understanding these mechanisms to develop treatments and potentially improve quality of life for affected individuals.

This study found that stem cells can temporarily act as non-professional phagocytes during hair cycle regeneration by clearing apoptotic cells through a process requiring local lipids and retinoids for activation, providing insights into their dual role in maintaining tissue integrity.

The document explains how hair follicles develop, their structure, and how they grow.

This review discusses melanocytes' role in pigmentation, their clinical significance in conditions like vitiligo and hair graying, and highlights current research on hair follicle regeneration without reporting new clinical results.

This study tested a novel cryo-carboxy dispensing device for treating androgenetic alopecia in six volunteers and found an unexpectedly rapid and positive response, with significant hair regrowth observed by day 90, prompting early conclusion of the trial.

In this review, researchers highlighted the potential benefits of using herbal remedies, such as Aloe vera, Bhringraj, Neem, Tea tree oil, Amla, and Hibiscus, for treating various hair problems like dandruff, scalp infections, and premature greying, suggesting natural alternatives to traditional hair treatments.

This study found that in sheep, the microRNA oar-miR-377 regulates hair follicle development by targeting the SLC24A2 gene, and identified a genetic variation associated with wool quality, suggesting potential markers for breeding.

In this study, a herbal oil formulation containing extracts from Martynia annua and Helianthus annuus seeds showed greater potential for hair growth in albino mice compared to finasteride and minoxidil.

The authors discuss BPH treatment options and highlight that while medications can manage symptoms, recent minimally invasive procedures may offer promise for elderly males who are not surgical candidates or wish to avoid surgery.

In this study, the researchers reported the detailed anatomical structure of horse skin, including the composition and organization of the epidermis, dermis, and associated glands and follicles.

Modern hair restoration techniques can effectively treat hair loss and provide natural-looking results.

Aging causes hair to gray and thin, with the timing of graying varying by race, and factors like oxidative stress and genetics can lead to hair loss.

In this study, researchers explored how hair follicle orientation is affected in the rosette fancy mouse and found that a mutation in the PCP gene Fzd6 caused reversed hair orientations in the posterior region, leading to the formation of unique whorls.

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 constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This study reports that in MRL mice, loss of p53 does not impair ear regeneration, suggesting p21's potential role in this process may involve the Tgfb/Smad pathway.

This genetic study identified a potential interval for the Marie Unna hypotrichosis gene but found no mutations in the nearby hr gene, suggesting its involvement remains unconfirmed.

This perspective suggests that browning agents may not directly enhance UCP1 expression in white adipose tissue but instead induce browning through increased heat loss, prompting thermogenesis to compensate.
