This study found that testosterone impacts hair follicles from both affected and occipital regions in male pattern androgenetic alopecia, but with different androgen response-profiles, challenging the belief that occipital regions are androgen-insensitive.

This study found that in early retinal neurogenesis in mice, the transcription factor Lhx2 regulates Sonic Hedgehog signaling by controlling expression of pathway genes like the co-receptors Gas1 and Cdon.

In this study, LHX2 and SOX9 were found to mark distinct epithelial progenitor cell populations within human hair follicles, suggesting roles in maintaining the hair follicle epithelium.

This article reviews how the skin's peripheral stress response system mirrors the central HPA axis, facilitating local homeostasis under stress, but presents no new findings.

This study found that cortexolone 17α-propionate (clascoterone) effectively inhibited androgen receptor-regulated transcription and IL-6 synthesis in scalp cells, potentially making it a promising candidate for topical treatment of androgenetic alopecia.

In this study, researchers found that the curliness of human hair is associated with an asymmetric structure at the cellular level, particularly in the differentiation of the precortex.

This study found that cultured outer root sheath cells from human hair follicles expressed a keratin profile similar to their in vivo environment, indicating environmental influence on keratin expression.

Proximal hair cortisol is a reliable tool for diagnosing Cushing's Syndrome.

Hair proteins change location and structure as hair cells mature.

This study found that local refinement of hair follicles into higher order patterns can occur without the core planar cell polarity system, but global alignment with body axes requires its function throughout development and regeneration.

This study developed a multiscale spatial atlas of healthy skin and basal cell carcinoma, revealing a hair follicle origin for BCC and the expansion of specific cell populations such as POSTN+ fibroblasts and RGS5+ pericytes, suggesting roles in skin cancer stroma expansion and vascular remodeling.

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.

This study reported that distinct stem/progenitor populations in the ocular surface epithelium have different cell division frequencies and respond differently to injury, with specific spatial compartmentalization and migration behaviors.

Hair cortisol concentration partly reflects HPA axis regulation but doesn't capture all its complexities.

This case study reports the clinical features of triple H syndrome in a 25-year-old man, including ACTH deficiency, alopecia universalis, and anterograde amnesia, which were improved with hydrocortisone treatment.

This study examined the expression patterns of various cytokeratins in the outer root sheath of human anagen hair follicles, noting distinct differentiation patterns and localization of keratin markers.

In this study, researchers found that the cornification process in the nuptial pads of Xenopus frogs involves the expression of the type II hair keratin homolog, krt59, and is regulated by the transcription factor hoxc13, showing similarities to mammalian hair evolution.

Hair cortisol levels decrease as children age, stabilizing around age 4.

This study provided a dynamic 4D atlas showing the development process of mouse hair follicles through a telescope-like model, revealing new insights into the origin of hair follicle stem cells.

This study reported a rare case where a pheochromocytoma produced ACTH, leading to cyclic Cushing syndrome, and underscores the importance of considering this possibility in cases of ACTH-dependent hypercortisolism with an adrenal mass.

This article reviews options and principles for reconstructing defects of the scalp, skull, orbit, and maxilla, but reports no new clinical results.

This study demonstrated that optical coherence tomography effectively detects significant changes in hair structure caused by steroid treatment, suggesting its potential use in doping control and clinical therapy monitoring.

This article reviews the complex challenges of managing scalp and cranial deformities post-trauma or surgery, advocating for better multidisciplinary approaches to enhance outcomes, but reports no new results.

This review discusses how the CRH/POMC systems may regulate human hair follicle pigmentation and highlights the concept of "self-similarity" in melanocortin systems at both local and systemic levels, without presenting new experimental results.

In this study, stress hormone CRF was found to inhibit hair growth, suggesting that the HPA axis is functional in human dermal papilla cells and contributes to hair loss under stress conditions.

This study found that OCT4-overexpressing human hair follicle mesenchymal stem cells show promise for artificial hematopoiesis by enhancing self-renewal through cytoskeletal remodeling and the beta-catenin-dependent adherens junction pathway.

This study characterized the Hoxc-13 gene from sheep wool follicles, noting its potential autoregulatory role and potential influence on skin function beyond hair keratin regulation.

This review discusses new developments in understanding the structure and properties of keratin fiber cell membrane complexes, without reporting new experimental results.

This study observed that human primary adult hair matrix keratinocytes may have the potential to generate hair follicle organoids, suggesting possible applications in hair follicle neogenesis and preclinical hair growth agent screening.
