This study suggests that dermal stem/progenitor cells can be enriched by intracellular granularity and display high proliferation and differentiation potential in vitro, distinguishing them from other fibroblasts and progenitors.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

This study found that polymeric micelle nanocarriers delivered pharmacologically relevant amounts of spironolactone to the epidermis and upper dermis, with higher delivery to pilosebaceous units, suggesting potential for treating glucocorticoid-induced impaired wound healing and pilosebaceous androgen-related skin diseases.

This review emphasizes the potential of repurposing topical L-thyroxine for skin ulcers and telogen effluvium and highlights the need for further exploration of its use in dermatology.

This study developed an efficient LC-MS bioanalytical method to simultaneously quantify minoxidil sulphate and latanoprost in skin layers, supporting the formulation of topical treatments for androgenic alopecia.

This study suggests that uncontrolled embryonic trichogenesis may play a role in the development of trichoblastoma in rabbits.

This review discusses causes of hair loss in cats, highlighting self-inflicted trauma due to flea allergy dermatitis, and presents no new clinical findings.

This study found that crossbred lambs fed liquid diets with reconstituted cow's milk initially grew wool without crimp, with crimp resuming two weeks post-weaning.

In this review, researchers discussed recent insights into caspases, enzymes initially associated with cell death and inflammation, revealing their broader roles in cell proliferation, migration, and differentiation, and highlighting the importance of caspase knock-out mice for understanding their implications in diseases.

In a double-blind clinical trial, this study found that a gel containing chitosan-coated spironolactone nanoparticles effectively reduced acne lesions over 8 weeks without adverse skin effects, suggesting potential for enhanced acne treatment through targeted skin delivery.

This review highlights the potential of nanoemulgel as a promising drug delivery system for lipophilic drugs, but presents no new experimental results; it discusses composition, preparation methods, and applications.

This study explored using a chitosan oligomer coating for topical delivery of dutasteride-loaded nanostructured lipid carriers, aiming to reduce systemic exposure and cytotoxicity.

This study found that CD99 is strongly expressed in the basal cells and hair follicles of normal adult and developing fetal skin, with expression patterns becoming similar after 20 weeks of gestation.

This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

This study observed that hairless HRS/J mice were resistant to Bacillus anthracis infection at the skin's surface, suggesting resistance may be due to increased dermal neutrophils rather than non-functional hair follicles.

This article discusses the minimal research on hair growth physiology and highlights Dr. Masumi Inaba's contributions to understanding androgenetic alopecia, but reports no new experimental results.

This study found that topically administered spironolactone in healthy volunteers resulted in no detectable systemic absorption or changes in related hormone levels over 72 hours, indicating local effect only.

In this study, researchers analyzed spaceflight data from various sources and found that skin issues during spaceflight are linked to DNA damage, mitochondrial dysregulation, and gene alterations, while also highlighting the skin's adaptability post-flight.

In this study, a mixture of tocopherol acetate, L-menthol, and stevioside was more effective in promoting hair growth in mice compared to tocopherol acetate or L-menthol alone.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This review discusses the role of skin enzymes in drug metabolism and emphasizes the need for models assessing enzyme activity to evaluate the safety and bioequivalence of topical generic drugs, highlighting efforts to standardize testing protocols for transdermal products.

This study observed that deleting PTEN in mouse facial motoneurons enhanced peripheral axon regeneration but also led to physiological changes and potential hyperplasia in older mice.

This study suggests that STAT3 signaling in keratinocytes is crucial for maintaining skin homeostasis by regulating hair follicle-specific keratin genes, potentially impacting dermatitis development through microbe-triggered inflammatory responses.

This case report highlights that hair loss, though common in the general population, may be a rare presenting symptom of Cushing's disease, as observed in a woman with multiple dermatological signs of the condition.

This study found that topical fulvestrant did not significantly improve hair growth parameters in men and postmenopausal women with androgenetic alopecia, unlike minoxidil, which was more effective in men.

This article reviews the anatomical and physiological characteristics of African American hair and skin, discusses common disorders and their management, but reports no new clinical findings.

This study found that epidermal stem cells in nonglabrous skin are connected to the distal end of the arrector pili muscle, which may play a role in epidermal renewal and wound healing.

This study found that NKIRAS2 expression affects skin tumor suppression and HRAS-driven transformation in mice, indicating its role in carcinogenesis depends on expression level and cellular context.

This study found that a mixture of plant extracts significantly improved skin barrier function, reduced inflammation, and exhibited anti-aging effects in human skin cells.
