In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

This study found that in neonatal mice, the absence of the NG2 proteoglycan leads to reduced epidermal thickness and delayed subcutis thickening due to impaired proliferation and adipocyte deficiencies.

This study found that ICAM-1 expression in murine skin is developmentally regulated and crucial for skin and hair follicle remodeling beyond its recognized role in immune responses.

This study demonstrates a varied distribution of keratins in the epidermis of the Malayan pangolin, suggesting evolutionary adaptations related to their distinctive scales.

This study reports that citrulline, uniquely found in the inner root sheath of hair follicles, can be specifically detected with the carbamido diacetyl reaction, resulting in a bright orange color.

This study found that cultured human foreskin cells and a human keratinocyte cell line continue to express specific cytochrome P450 isoenzymes, unlike keratinocytes derived from hair follicles.

This study found that in bovine skin, leptin and its receptor are expressed in the epidermis and hair follicles, suggesting a role in epidermis growth and hair follicle cycling through paracrine and autocrine mechanisms.

This study found that CD90+ cells, resembling mesenchymal stem cells, are abundantly present in the lower part of anagen hair follicles in dogs.

This study found that the expression of laminin-511 and -332 was significantly increased in psoriasis skin lesions and may influence keratinocyte proliferation and apoptosis, suggesting a previously overlooked role in the disease's pathogenesis.

This study observed that radioactive sulphur appeared in rat and mouse hair follicles more quickly than in lambs, possibly linked to faster hair growth rates in the rodents.

This study demonstrated radiocalcium uptake in skin, eye, cartilage, and mucous glands, with the highest concentration in the hair follicle's keratogenous zone.

In this study, researchers found that the matriptase-HGF-c-MET pathway may be activated in proliferative cells of human hair follicles and sebaceous glands, suggesting a potential role in hair growth regulation.

This study found that Sox9 was variably expressed in most canine skin neoplasms, particularly in those originating from the hair follicle's bulge region, suggesting its potential as a stem cell marker.

This study found that CD90+ stem cells with fibroblast-like morphology are present in the lower part of the anagen hair follicle in dogs.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

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.

In this study, researchers reported telocytes in the dermis of silky fowl embryos at different developmental stages, highlighting their immunophenotypes and interactions with other cells.

This study demonstrated that treating platelet-rich plasma with ozone or procaine in vitro led to distinct changes in platelet activity, significantly enhancing the release of platelet-derived factors without damaging the platelets, indicating potential for improved regenerative therapies.

This study found that patients with alopecia areata and androgenetic alopecia showed increased c-kit expression and decreased Ki-67 expression in hair follicle cells compared to controls, suggesting a possible feedback mechanism involving stem cell factor signaling.

This study found that COX-2 expression in normal rat skin is linked to the hair cycle, with varying levels observed in different skin structures during anagen, catagen, and telogen phases.

This study found that human scalp hair follicles can internally operate a Cori cycle, synthesize glycogen in the presence of lactate, and modulate growth through glycogen phosphorylase activity.

This study found that NGAL expression increased in calcium-induced keratinocyte differentiation in vitro and was highly elevated in psoriasis-like skin conditions and skin cancers, suggesting a role in skin hyperplasia and homeostasis.

This study demonstrated that supplementing aged mice with pro-IGF-II improved muscle regeneration by enhancing satellite cell proliferation and reducing adipogenesis, suggesting potential benefits for treating muscle injuries in elderly individuals.

This study suggests that decorin may help maintain hair follicle stem cells and its reduced expression could contribute to age-related hair loss.

This study demonstrated that stem cells from the small intestine can differentiate into skin cells and reduce skin damage in irradiated mice, supporting the theory of stem cell plasticity.

In this study, the researchers observed that male pattern alopecia is characterized by miniature follicles, enlarged sebaceous glands, and an increased number of mast cells, without significant abnormalities in enzyme activity.

This guide reviews the biology of sebaceous glands and their evaluation methods, emphasizing their roles beyond lipid production in skin health and disease, and reports no new research results.

This study found that basal cell carcinomas show strong expression of vitamin D receptors at both mRNA and protein levels, suggesting a potential role in tumor growth regulation.

In this study, old age was concluded not to be a significant cause of hair loss, with most cases in the elderly appearing to be androgen-driven.

In this study using rats, finasteride-induced DHT deficiency led to morphological changes in seminiferous tubules, linked with altered junctional protein expression, potentially impairing fertility.
