In this study, VEGF165 induced hair follicle stem cells to differentiate into vascular endothelial cells, potentially supporting angiogenesis and neovascularization, with the Notch signaling pathway affecting differentiation efficiency.

Sox13 is a new marker for early hair follicle development and differentiation.

This review discusses the role of Hedgehog signaling in epidermal and hair follicle development and its involvement in basal cell carcinoma, without reporting new empirical findings.

This study revealed that nestin-expressing progenitor cells capable of becoming ORS keratinocytes are present during both hair follicle development and in adult hair follicles.

This study investigated transcription factors in human trophectoderm cells during development, finding that GATA2 and GATA3 are essential for transforming stem cells into induced trophoblast stem cells, which display characteristics similar to placental progenitor cells, offering new methods for modeling placental-associated diseases.

Key signals for hair follicle formation were identified.

This study found that synchronized signals in the microenvironment regulate stem cell lineage choices in hair follicles by influencing chromatin dynamics during regeneration.

This article reviews the role of skin appendages in wound healing and appendage regeneration, discussing cellular and molecular mechanisms but reports no new experimental findings.

This study found that transplanting genetically modified dermal fibroblasts into full-thickness skin defects in rats led to the formation of hair follicles with mature pilosebaceous systems by 16 weeks.

In this study, researchers found that the G(S)alpha subunit is strongly expressed in neonatal mouse hair follicles, indicating it may play a role in initiating follicle growth.

This review discusses recent advancements in hair follicle regeneration technologies, including the authors' own development of functional hair regeneration through bioengineered follicle germ transplantation, but reports no new clinical results.

This study found that in yak hair follicles, TGF-β2 significantly contributes to the transition from growth to regression phases via inducing apoptosis, whereas HSP70 appears to inhibit follicle regression by protecting epithelial cells from apoptosis.

This study observed that Hedgehog signaling in reticular and papillary fibroblast lineages plays different roles in wound repair and de novo hair follicle formation.

This study reported that Hedgehog signaling in papillary fibroblasts is crucial for hair follicle regeneration during wound healing, emphasizing its potential for developing regenerative therapies in scarring wounds.
