This study found that the microRNA miR-22 is a key regulator of the hair cycle, influencing hair loss by promoting the transition from growth to rest phases and repressing keratinocyte differentiation.

This review discusses mesenchymal stem cells' role in tissue regeneration and skin anti-aging, highlighting their migration to damaged sites and secretome effects, but reports no new clinical results.

This study suggests that equine adipose tissue stem cells may be a promising option for cellular regenerative therapy in equines due to their differentiation capabilities and proliferation potential, but further molecular characterization is needed.

This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.

This study found that the transcription factors Msx2 and Foxn1 are crucial for maintaining Notch1 expression in the hair follicle matrix, which is necessary for proper hair differentiation.

This study found that overexpression of Hoxc13 in GC13 mouse models affects hair follicle differentiation by interacting with medulla-specific genes, particularly Foxq1, suggesting a regulatory pathway for medulla differentiation.

This study found that transient non-lethal levels of endogenous ROS in cultured human hair follicles promoted entry into the growth phase by activating the hair follicle stem cell niche.

This study found that bulge-derived keratinocytes from human follicles were more resistant to differentiation compared to epidermal keratinocytes, possibly due to WIF-1 involvement.

This study found that nestin-negative hair follicle stem cells can differentiate into neural stem cell-like cells, but not mature neurons, through a multi-step neuro-induction process.

This study found that bone marrow mesenchymal stem cells from Guizhou miniature pigs showed stable growth and multidirectional differentiation potential, making them ideal for tissue engineering applications.

This study found that polycaprolactone (PCL) in facial fillers led to more cell proliferation and vascular activity than hyaluronic acid (HA) in Wistar rats, suggesting enhanced tissue regeneration effects with PCL.

Androgenic alopecia causes hair follicle degradation and skin restructuring, but some hair elements remain.

Adipose-derived stem cells can be transformed into hair-forming cells using specific extracellular vesicles, offering potential for hair regeneration therapies.

This study found that activation of Wnt/β-catenin signaling in mouse testes promotes spermatogonial differentiation and reduces the stem cell pool, with SHISA6 inhibiting this process and maintaining stem cell characteristics.

This chapter reviews genetic defects in female sexual differentiation, focusing on 46,XX disorders of sex development and the impact of genetic factors and sex steroids on development, but reports no new clinical findings.

This research found that androgen bioactivity plays a role in normal female sexual differentiation, suggesting females develop within a significant androgenic environment, with implications for understanding conditions like congenital adrenal hyperplasia.

This study reports that Lef1 plays a crucial role in promoting bulge stem cell differentiation towards hair fate by activating β-catenin and downstream signaling pathways during hair follicle development.

This study found that the EDAR 1540T/C genetic variant is significantly associated with hair thickness variation in Japanese populations, enhancing previously observed associations in Southeast Asian groups.

In this study on Drosophila wings, researchers identified 435 genes with significant expression changes during wing hair morphogenesis, and found new phenotypes for 9 genes through functional validation.

This study found that doxorubicin induces hair follicle apoptosis through TRAIL receptor signaling, providing insights for managing chemotherapy-induced hair loss.

This review systematically analyzed literature to differentiate desmoplastic trichoepitheliomas from other cutaneous tumors based on clinical, histopathological, and immunohistochemical features but reports no new clinical results.

This study found that transverse sections of scalp biopsies, particularly looking at the anagen:non-anagen hair ratio and presence of pigment casts, effectively distinguish alopecia areata from androgenetic alopecia.

This study found that PDGF-BB affects human melanocytes differently depending on their differentiation stage, stimulating melanoblast proliferation but inhibiting melanocyte proliferation while promoting their differentiation.

This study found that in mice, knockout of Rac1 and Rac3 in keratinocytes led to reduced white adipose tissue and revealed Rac-dependent paracrine pathways affecting pre-adipocyte differentiation.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This study reported that certain minoxidil conjugates, specifically those with spermine, methylenedianiline, and diaminofluorene, were able to induce differentiation in HL-60 acute myeloid leukemia cells without toxicity at a concentration of 10 μM.

This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

This study found that ectopic expression of Whn in transgenic mice caused impaired differentiation in epidermis and hair follicles, with hair growth defects and severe urinary tract issues leading to hydronephrosis.

This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

This study observed dynamic behaviors such as cluster formation, migration, and active proliferation of transplanted bone marrow cells in a mouse model, providing insight into cellular-level changes post-transplantation.
