This study found that hypertrophic chondrocytes at the fracture callus border may convert to osteoblasts, influenced by vasculature and pluripotency gene expression.

The researchers in this study found that neonatal mouse skin fibroblasts show distinct chromatin landscapes directing differentiation into dermal papilla or adipocyte lineages, and such plasticity may inform strategies for enhancing regenerative capacities in adult skin.

This study found that the fuzzy mutation in mice is linked to both structural hair defects and accelerated hair follicle cycling, influencing the regulation of hair cycle phases such as catagen and anagen.

Skin organoids can regenerate hair by forming specific cell units with certain signals.

This mini-review discusses human hair follicle development and summarizes genetic disorders linked to abnormalities in hair follicle morphogenesis, structure, or regeneration, but reports no new experimental results.

This review highlights the critical role of TGF-β and FGF signaling pathways in the development and regeneration of skin layers, particularly the dermis, and discusses their significance in advancing future clinical applications in dermatology.

This study found that in a mouse model of Gorlin syndrome, constitutive activation of signaling in dermal cells led to abnormal follicular growth, indicating non-epidermal factors may contribute to the disease.

This study reports that different adhesion molecules play distinct roles in the morphogenesis of feathers and hair, influencing processes such as mesenchymal condensation, epithelial folding, and cell death.

This study found that intermediate filaments and matrix proteins in presumptive hair shaft cells are synthesized sequentially, identifying a new polypeptide component that changes during hair cell differentiation.

This narrative literature review examined how linking embryonic development with non-genetic skin anomalies can improve diagnostic accuracy, guide prenatal counseling, and enrich dermatology education by revealing specific vulnerabilities in skin morphogenesis and supporting advances in regenerative medicine.

This review examines how fibroblasts contribute to regeneration in various organs and explores the potential of reverting adult fibroblasts to a fetal-like state for regenerative therapies, but reports no new empirical findings.

This study describes the development of a new embryonic stem cell culture system that allows for the differentiation into mature hair follicle cells, potentially aiding research in hair follicle formation and regeneration.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

This study provided a dynamic 4D atlas showing the development process of mouse hair follicles through a telescope-like model, revealing new insights into the origin of hair follicle stem cells.

This review discusses the cyclical phases of hair follicle transformation and the various factors that regulate hair growth, reporting no new clinical results.

This study observed three hair follicle-like cells from cultured human foreskin keratinocytes, suggesting a potential basic framework for hair regeneration applications.

This review outlines the evolution of hair follicle engineering and its foundational discoveries, but reports no new experimental results.

This study found that the expression of the sonic hedgehog protein is involved in wound healing texture regeneration, inhibiting skin texture after embryonic day 14 and affecting keratinocyte migration and division.

This study demonstrated that the human thymus contains clonogenic thymic epithelial cells capable of self-renewal and maintaining a thymic phenotype in a specific culture system.

This study used single-cell RNA-sequencing data from mouse skin to reveal that fibroblasts show high transcriptional plasticity during wound healing, forming transient microniches early on and stratifying scar tissue into distinct molecular layers over time.

This article reviews the evolving understanding of hematopoietic stem cells, including their heterogeneity and the role of cytokines in lineage determination, and reports no new results.

This study found that injecting thymus gland extracts into albino rats significantly accelerated growth and morphological differentiation across generations, including earlier sexual maturation and development of features like hair and teeth.

This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.

This study found that modulating Wnt signaling can promote new hair follicle regeneration in adult mouse skin wounds, suggesting potential treatment strategies for scarring and alopecia.

This study found that tissue-engineered skin using mouse fibroblasts successfully supported hair growth after grafting, but similar success was not observed using human fibroblast-derived tissue.

This study found that interleukin-1α and interleukin-7 secreted by keratinocytes enhance the proliferation of γδT-cells and epidermal stem cells, revealing mechanisms of stem cell activation during wound healing in mice.

This study found that histidine decarboxylase is crucial for the hair-inducing ability of newborn mouse dermal cells, with its expression significantly decreasing in the first few days after birth.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.
