This study found that estrogen treatment induced premature catagen and apoptosis in hair follicles of wild-type mice, while having no effect on mice lacking estrogen receptor α.

This study visualized mitochondrial metabolism in cultured bovine hair follicles and plucked human hairs, finding that ROS and mitochondrial polarization correlate in specific hair follicle regions, particularly near keratin deposition sites.

In this study, researchers observed that estrogen and its receptors play a crucial role in hair growth and control, with notable sex-dependent differences in human scalp hair follicles.

This study reported significant transcriptomic changes in keratinocyte and immune cell populations in a mouse model with EGFR-deficient epidermis, suggesting possible targets for mitigating adverse skin events in EGFR-targeted cancer therapy.

This case study and literature review describe eruptive vellus hair cysts as uncommon, potentially inherited or acquired lesions, associated with other skin conditions, and challenging to treat despite being benign.

This study reports a case of cystic panfolliculoma, highlighting the role of epithelial-mesenchymal interactions in its pathogenesis and explaining its histological resemblance to trichofolliculoma.

Estrogen receptor α controls hair growth cycles and skin thickness in male mice.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

This review examines the clinicopathologic features of perifollicular elastolysis and indicates that, while its presentation is consistent, there is a lack of high-certainty evidence for effective treatments.

This study builds on previous findings by associating female pattern hair loss with gene polymorphisms related to oestrogen activity, suggesting oestrogen's role in the condition.

This study observed that the keratinization pattern of trichilemmal cysts in two Japanese women may originate from the proliferation of the outer root sheath in the follicular isthmus of anagen hairs.

This review discusses the physiological roles of ovarian androgens in follicle development and atresia, emphasizing their contributions to polycystic ovary syndrome and normal follicle maturation but provides no new clinical results.

This study observed that amelanotic melanocytes from human hair follicles appeared morphologically immature, suggesting they might not transfer melanosomes into keratinocytes.

This case report describes the presence of a teratoma within an equine antral follicle and suggests that the ovary maintained functionality despite the teratoma, as indicated by active antral follicles and recent ovulation.

This study found that in a mouse model of PCOS, high androgen levels caused pyroptosis in ovarian granulosa cells and increased ER stress in oocytes, reducing oocyte maturation rates, while treatment with CPA and DMF improved these rates.

This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.

This study found that electrical epilation in organ-cultured human scalp skin perturbs hair follicles by causing inflammation, impairing melanin production, and possibly inhibiting post-epilation hair re-growth.

This study observed specific expression patterns of three zebrafish estrogen receptor genes during development, highlighting robust co-expression of esr2a and esr2b in primary neuromasts, branchial arches, and other tissues.

This study suggests that human scalp hair follicles express erythropoietin and its receptor, up-regulating receptor expression under hypoxic conditions, and may mimic another hypothalamus–pituitary axis equivalent involving the TRH-TSH system.

This study reports that EGF at specific concentrations promotes the proliferation and migration of hair follicle ORS cells by activating the Wnt/β-catenin signaling pathway in vitro.

This case report describes a 47-year-old woman diagnosed with a rare Sertoliform endometrioid carcinoma of the ovary, emphasizing its early-stage presentation and generally favorable prognosis.

This study found that miRNA expression profiles in follicular fluid are altered in women with PCOS, with certain miRNAs potentially useful for distinguishing patient subtypes and contributing to understanding PCOS heterogeneity.

This study found that EGF receptors are aberrantly regulated and persist in cholesteatoma epithelium, suggesting a hyperproliferative character compared to normal human skin.

This case study reports a peculiar variant of an epidermal cyst in a patient, featuring unique characteristics like brownish, lumpy contents resembling bone marrow.

This study found that Ber-EP4 immunoreactivity is present in specific areas of hair follicles across different stages of the hair cycle, particularly in the secondary hair germ, but not in mature anagen follicles.

This study found that epimorphin is closely linked to developing hair follicles in human fetuses, suggesting it plays a significant role in hair follicle morphogenesis.

This study found that human hair follicles emit electromagnetic fields due to metabolic activity linked to S100 proteins, visualized using a novel microscopic technique with nano-sized iron particles.

This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.
