In this study, researchers observed that EGFR deficiency in the epidermis affects gene expression related to cell differentiation and structure, highlighting spatial and temporal roles of EGFR during skin and hair follicle development.

This review examines current understanding of hair graying and suggests it may be caused by depletion of melanocyte stem cells due to genotoxic stress or dysfunctional melanocytes from oxidative stress.

This study found that BRG1 is crucial for keratinocyte migration during skin wound healing, as its suppression impairs wound closure by inhibiting migration without affecting cell proliferation or apoptosis.

This study found that inhibiting TGF-β receptors in adult dermal fibroblasts restored their function and increased resistance to Staphylococcus aureus infection by enhancing their adipogenic and antimicrobial capabilities.

In this study using a transgenic mouse model, Id2 overexpression in hair follicle stem cells prolonged quiescence by affecting gene expression, partly independent from BMP signaling.

Hormones cause hair loss by affecting cell growth and weakening cell attraction.

In this study, upper-bulge epidermal stem cells in mouse hair follicles were shown to play a role in forming tactile sensory units by creating an extracellular matrix that supports nerve interactions.

This review discusses the human Nude/SCID phenotype and FOXN1 gene's role in immunological disorders affecting T-cell development but reports no new clinical findings.

This study found that mutations in the hairless gene in mice disrupt hair follicle integrity during catagen, leading to baldness due to disintegrating epithelial structures and loss of normal dermal papilla.

This paper highlights the growing interest in exosomes for their therapeutic and diagnostic potential in cosmetic dermatology, noting their roles in skin rejuvenation, postprocedural care, and antiaging treatments.

This review discusses the role of microRNA in skin development and disease, highlighting its potential for novel therapies, and reports no clinical results.

This research found that melatonin plays a protective and modulatory role in skin biology, reducing UV damage and chemotherapy-induced hair follicle cell harm in human organ culture models.

This review highlights how diabetes affects stem and progenitor cells through altered signaling and homeostasis, impacting tissue function and complicating diabetic therapy efforts; new clinical results are not presented.

This study discusses the potential association between low vitamin D levels and insulin resistance, suggesting that vitamin D deficiency may contribute to disorders like obesity and diabetes, but emphasizes the need for further research to confirm these links.

This study found that loss of the Ptch2 receptor in mice leads to increased incisor growth and enhanced mesenchymal stem cell differentiation, highlighting Ptch2's role in organ regenerative potential.

This study found that tildacerfont treatment in males with congenital adrenal hyperplasia reduced androgen levels and improved markers of testicular function, suggesting potential benefits for male reproductive health.

This study found that reduced plasma DIAPH1 levels were associated with polycystic ovary syndrome, suggesting DIAPH1 as a potential predictive factor for the condition.

This study suggests that hemoglobin α expression in the epidermis is induced by oxidative stress and may function as an antioxidant, contributing to skin barrier function.

This systematic review suggests that human placental extracts may offer therapeutic benefits for non-communicable diseases such as liver pathologies and metabolic disorders, but larger trials are needed to confirm efficacy and understand molecular pathways.

Senescent melanocytes in nevus skin boost hair growth.

This review discusses the multiple factors contributing to skin aging, including cellular changes and environmental influences, and highlights its recognition as a disease with significant implications beyond cosmetic concerns, without reporting new research results.

This study found that the dysfunction of hair follicle dermal stem cells with age contributes to hair follicle aging and hair loss in mice.

This study found that hair follicles play a significant role in regulating skin barrier function, with disruptions in the upper hair follicle affecting the epidermis, influencing processes like desquamation and sebum release, and leading to cell movement into the epidermis.

In this study, researchers demonstrated that the expression of the oncogene SmoM2 leads to basal cell carcinoma in the ear epidermis of mice but not in the back skin, with differences in susceptibility linked to the composition of the extracellular matrix.

Caspase-7 has functions in skin and hair that are not related to cell death.

This review explores regenerative treatment options for non-scarring alopecia, with a focus on the potential of mesenchymal stem cells for hair regrowth, but it reports no new clinical results.

In this study, researchers found that hair follicles and dermal fibroblasts, including dermal papilla cells, supported sustained hair growth in transplanted murine models, with RNA-seq analysis revealing active signaling pathways and gene expression patterns.

This review introduces in vitro evaluation methods for whitening, anti-wrinkle, and hair growth cosmetic ingredients but reports no new experimental results, highlighting the need for better human-correlated methods and reliable biomarkers.

This abstract discusses the importance of developing intelligent and multifunctional dressings with skin-like properties for real-time wound monitoring, highlighting their potential to improve wound management, prognostic evaluation, and the integration of health monitoring into clinical practice.

This study suggests that black ginseng concentrate protects human follicle dermal papilla cells against oxidative stress, potentially offering a natural approach to prevent cellular dysfunction linked to hair loss.
