This source provides procedural details without reporting new experimental findings or conclusions.

In this study, Er:YAG laser therapy initially improved the appearance of eruptive vellus hair cysts but was ultimately ineffective due to early recurrence and concerns about atrophy or scarring.

This case report highlights the importance of histopathological examination in accurately diagnosing eruptive vellus hair cyst due to its rarity and resemblance to other conditions.

This review describes how liver and kidney diseases and diabetes may affect ethyl glucuronide levels in hair, impacting forensic and clinical interpretations, but reports no new experimental results.

In this animal study, topical VEGF gel increased hair growth and thickness in Mesocricetus auratus, although it was not completely inert, highlighting the need for further toxicity confirmation.

This study categorizes the human fetal vaginal epithelium into four areas with distinct transcriptomic profiles, aiding potential advancements in vaginal reconstruction and drug delivery.

This study observed that EZH2 expression scores in the epidermis, dermis, and hair follicles decrease with gestational age in human fetuses, and these scores were significantly higher in adults, indicating that lower EZH2 levels may be required for full skin differentiation and maturation before birth.

This review summarizes the therapeutic potential and development of engineered extracellular vesicles for tissue repair and regenerative medicine, reporting no new clinical findings.

This study found that direct immunofluorescence of hair is a simple and non-invasive alternative for monitoring pemphigus vulgaris, matching skin biopsy results in the cases observed.

This study found that multiphoton microscopy imaging allows for detailed observation and quantitative analysis of collagen alterations in the progression of endometrial cancer, potentially offering a faster, more accurate method for early diagnosis compared to current protocols.

Histopathology is crucial for accurately diagnosing eruptive vellus hair cysts.

This study found that injections of extracellular vesicles derived from mesenchymal stem cells improved hair growth in over 50% of female and nearly 80% of male patients after six months.

This review discusses the use of extracellular vesicle-loaded hydrogels in tissue regeneration and reports no clinical results; the authors highlight their potential and suggest future research directions.

This case report describes a 24-year-old male with eruptive vellus hair cysts on his forehead and explores the use of extraction videodermoscopy as a new, less invasive diagnostic method, potentially replacing the need for skin biopsy in diagnosing such skin conditions.

In this study, researchers identified a highly reactive, isozyme-specific sequence for TGase 3, contributing to understanding its distinct functional role and activity distribution in the mouse epidermis.

This study reports an improved method for determining blood type from human hair using immunohistochemistry.

This study reveals that CSPG4-positive basal cell keratinocytes show distinct global gene expression from CSPG4-negative cells, despite similar colony-forming efficiency.

This study found that methylene blue staining helped identify late catagen and telogen hair follicles more accurately than unstained follicles, which suggests that established telogen percentage standards may be overestimated.

This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

This study found that 15 ng/mL of EGF was the most effective concentration for stimulating goat hair follicle stem cells in vitro.

This research identified K31 as a new marker for distinguishing clear secretory cells in human eccrine sweat glands, aiding in differentiating between distinct cell types within these glands.

This study found that the expression of CK 15 and CK 19 in vitiligo patients undergoing phototherapy was correlated with improved repigmentation, suggesting their potential as markers for stem cell stimulation.

This study found that excess vitamin A in organ cultures of mouse embryos led to significant changes in epidermis and hair follicles, altering morphogenesis and polysaccharide distribution.

This preclinical study found that exercise-induced extracellular vesicles delayed breast cancer tumor growth in mice, potentially by enhancing the immune response within the tumor microenvironment.

Skin problems like acne, dry skin, and nail and hair changes are common in patients taking EGFR inhibitors.

This study found that extracellular vesicles derived from hair follicle mesenchymal stromal cells demonstrated similar potential to those from adipose tissue in promoting cell proliferation and migration, enhancing angiogenesis, and protecting cells under stress, suggesting promise for chronic wound treatment.

Glycogen helps E. coli cells divide unevenly and organize their contents.

In this study, the staining properties of two types of cysts, epidermal and pilar, were found to differ, supporting their origins from the epidermis and the trichilemmal hair follicle layer, respectively.

This study observed that plant-derived extracellular vesicles delivered through a microneedling technique showed favorable tolerance and subjective improvement in androgenetic alopecia patients, with 95% reporting perceived improvement and 85% experiencing no adverse effects after six sessions.

In this study, dermoscopic examination of COVID-19 patients revealed significant microvascular changes in the proximal nailfold, such as avascular areas and disorganized capillary architecture, compared to healthy controls, with some regression of these changes observed over time.
