This study found that the corneal epithelium differentiation program can proceed independently of lens formation, suggesting the corneal program is the default in eye development.

In this study, researchers mapped gene expression in developing hair follicles to reveal unknown cell populations and markers, suggesting early establishment of cell fates in hair placodes.

In this study, researchers found that the transcriptional program regulated by PRC2 is not necessary for maintaining hair follicle stem cell quiescence and hair regeneration in vivo.

This study found that activating CXCR2 on ras-transformed keratinocytes promotes migration and tumor development in a mouse skin model.

This article reviews neuroendocrine abnormalities in polycystic ovarian syndrome and reports no new findings, highlighting areas such as the hypothalamus-pituitary axis and genetic basis.

This classification proposal introduces a novel system for categorizing cutaneous adnexal cysts based on their origin in the folliculosebaceous unit and sweat glands, aiming to simplify and enhance understanding of these skin lesions.

Mesotherapy might help with hair and scalp problems.

This report describes a paraneoplastic alopecia in four cats associated with internal malignancy, confirming previous findings of a syndrome linking ventral alopecia and metastatic carcinomas.

This study found that trichoblastomas and nodular basal cell carcinomas have similar cytokeratin expression patterns, indicating differentiation towards the outer root sheath epithelium.

This study found that hair cortisol did not indicate expected hypercortisolism in acutely underweight anorexia nervosa patients and did not change significantly during short-term weight restoration.

This case report highlights the potential benefits of unilateral adrenalectomy in treating primary bilateral macronodular adrenal hyperplasia, noting a high rate of remission and low risk of recurrence.

This study found that Par3 plays a crucial role in maintaining epidermal homeostasis by regulating Rho/actomyosin contractility and ensuring mitotic accuracy, with potential implications for other self-renewing epithelia.

This study found that dermal papilla cells in culture may enhance and attract follicular epithelial cell growth, suggesting their pivotal role in hair and follicle development.

This study found that high doses of TCB caused severe toxicity in cotton top marmoset monkeys, with clinical and histological changes similar to those in humans and other primates exposed to PCBs.

This case report presents a very rare instance of pilonidal sinus in the preauricular region, marking only the second known case documented in medical literature.

This study found that nevoid basal cell carcinomas originate in the epidermis and upper hair follicles, resembling early nonnevoid basal cell carcinoma proliferations.

This study suggests that incorporating matrisomal components into biomaterials could enhance skin wound healing in mammals that do not naturally regenerate tissues like the axolotl and Acomys.

This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

This paper discusses a method for eyebrow reconstruction using intermediate hair from the forehead hairline with a pedicled temporoparietal fascial flap and reports no new clinical results.

This study developed a molecular systems architecture to map the complex interactions between mesenchymal stromal cells and their microenvironment, providing a framework for future predictive models that could enhance therapeutic strategies and reduce adverse effects.

In this study, researchers observed that P2X3-immunoreactive fibers extensively innervate the epidermis of rats, suggesting a primary role in detecting noxious stimuli in cutaneous tissue.

In this study on Drosophila embryos, researchers observed that the Slit/Robo signaling pathway is crucial for the collective migration and proper positioning of Posterior Signaling Center cells within the hematopoietic niche, highlighting its role in niche assembly and cellular organization.

This review discusses the paracrine function of mesenchymal stem cells in tissue regeneration and repair, focusing on secreted bioactive substances and their role under different microenvironments; it reports no new clinical results.

This study investigated peptidergic nerve fibers in sinus hair follicles of various mammals and found that CGRP fibers were more densely distributed than SP fibers across different regions of the follicles.

This review discusses primary cicatricial alopecias, detailing their classification, pathogenesis, clinical features, histopathologic findings, and treatment, without reporting new experimental results.

This study found that disruptions in planar cell polarity signaling are implicated in congenital heart defects and cardiomyopathy in developing mouse hearts, associated with early cardiomyocyte disorganization and improper heart looping.

This study suggests that keratin expression in keratoacanthomas resembles that in the upper part of hair follicles, implying a potential origin, but it is indistinguishable from squamous cell carcinomas in terms of keratin reactivity.

This article reviews insights into the pathogenesis of primary cicatricial alopecias, such as lichen planopilaris, provided by emerging technologies, but it does not report new clinical results.
