This study found that ribbed hairs on tarantulas closely resemble chemoreceptors rather than silk-producing spigots, with no silk observed emitting from them under microscopy.

This review discusses the potential benefits and biological activities of MSC secretome for various skin applications, but it reports no new clinical results.

This study found that the ARL15 gene affects adipocyte differentiation and adiponectin secretion, and suggests that ARL15 haploinsufficiency may predispose individuals to lipodystrophy.

In this study, the researchers found that constitutive activation of the EGFR in mice led to increased sebum production, enlarged sebaceous glands, and altered gene expression related to sebocyte proliferation and lipogenesis.

This study found that three months of oral finasteride treatment significantly decreased dihydrotestosterone levels and hair growth in hirsute women without negatively affecting gonadotropin secretion.

This case study describes a testosterone-secreting adrenal adenoma in a 55-year-old woman, highlighting the presence of Reinke's crystalloids, suggesting that Leydig cells may play a role in such tumors.

This case report describes a functional adrenocortical oncocytoma that co-secreted testosterone and cortisol.

This review discusses the diagnostic challenges of androgen and estrogen-secreting adrenal tumors and highlights that the presence of metastases is the most reliable indicator of malignancy; it reports no new clinical findings.

This study found that photobiomodulation enhanced hair regeneration in injured dermis of mice, likely through increased migration and exosome secretion of dermal papilla cells via the Akt/GSK-3β/β-catenin pathway.

This case study describes an extremely rare instance of androgen-secreting adrenocortical carcinoma in a patient with non-classical congenital adrenal hyperplasia.

This study found that while both natural and bioengineered salivary glands showed similar protein concentrations in response to taste stimulation, their protein compositions and amylase concentrations differed, which may affect nerve signal balance.

This case study suggests that low leptin levels in obese hyperandrogenic postmenopausal women might indicate the presence of androgen-secreting tumors.

This review suggests that the umbilical cord-derived mesenchymal stem cell secretome presents a promising approach for skin regeneration and wound healing due to its multiple therapeutic properties, highlighting its potential over traditional treatments for conditions like chronic wounds and alopecia.

This review presents evidence supporting the potential of adipose-derived stem cell secretome as a promising cell-free therapy for skin repair, emphasizing its application in wound healing, alopecia, skin rejuvenation, and inflammatory skin diseases.

This study developed immortalized human hair follicle-derived mesenchymal-like stromal cells (iHF-MSCs) as a consistent source of therapeutic secretome, reporting their superior immunomodulatory and regenerative performance, potentially advancing cell-free therapies for inflammation and tissue repair.

In this study, a topical application of Lotus corniculatus seed extract significantly reduced sebum production and skin oiliness in humans through inhibition of lipid synthesis pathways.

This case report highlights that in postmenopausal women with severe hyperandrogenism, thorough adrenal and pelvic evaluations, hormonal profiling, and permanent pathology are essential for accurate diagnosis and management of androgen-secreting tumors, such as AGCTs, to prevent misdiagnosis and ensure effective treatment.

This study found that a hair tonic containing 10% mesenchymal stem cell secretome significantly increased hair density in volunteers with alopecia after eight weeks, suggesting its potential as an effective treatment option for hair growth stimulation.

In this study, researchers explored ubiquitination patterns in healthy human skin and CYLD cutaneous syndrome tumors, identifying extensive ubiquitin sites and differential protein ubiquitination linked to tumor pathology, highlighting the role of ubiquitination in tissue architecture and disease mechanisms.

This review highlights the potential of mesenchymal stem cell secretome for developing topical treatments aimed at skin regeneration and treating various diseases, but notes a lack of studies on safety, efficacy, and standardization processes for its clinical use.

This study found that neurosteroids influence oxytocin secretion in sheep, particularly during stress and pregnancy, suggesting their role in protecting and maintaining pregnancy under harmful conditions.

This case report highlights the diagnostic challenge of identifying androgen-secreting ovarian Leydig cell tumors in postmenopausal women when imaging fails to reveal masses, emphasizing the usefulness of ovarian vein sampling for localization.

This study found that in male mouse pancreatic islet β cells, testosterone enhances glucose-stimulated insulin secretion by being locally converted into dihydrotestosterone and estradiol.

This study found that synthetic ceramide shampoo improved dandruff and erythema while reducing water loss when compared to control in a group of 20 subjects over four weeks.

This study demonstrated that in genetic mouse models, the calcium sensor Stim1, not Stim2, is essential for sweat secretion in sweat glands.

This case report describes a 69-year-old woman with hirsutism and elevated serum testosterone, where surgery resolved symptoms and serum testosterone, suggesting ovarian steroid cell tumor consideration in similar profiles.

This study developed a method to quantify hormones in skin secretions and found that hormonal composition varies by sex and anatomical site.

This case study details a 57-year-old woman with symptoms of androgen excess, including rapid hair growth and temporal balding, alongside abnormal testosterone levels and a history of chronic renal failure.

This case series highlights that diagnosing ovarian Leydig cell tumors can be challenging, and expert sonography is crucial for accurate identification, as imaging modalities like CT, MRI, and PET-CT may fail to detect them.

This case report describes an 80-year-old woman with severe androgenic alopecia linked to Leydig cell hyperplasia in an ovarian cyst, highlighting the need to investigate androgen-secreting tumors in similar cases.
