This review discusses the role of intermediate filaments in cell signaling and differentiation, emphasizing their impact on stem cell function, development, and disease, but reports no new clinical results.

Mesenchymal stiffness affects sweat gland cell development.

In this study using transgenic mice, activating P-catenin signaling induced new hair follicle formation and maintained follicle tumors, with implications for understanding skin homeostasis.

This study reveals that the microRNA-200 family, highly enriched in hair matrix progenitors, restricts sebaceous gland development by inhibiting the SOX9-dependent lipogenic program, highlighting its specific role in epithelial plasticity within hair follicles.

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 study found that the combination of TTNPB and CHIR99021 enhanced the derivation of highly advanced neural stem cells from human pluripotent stem cells, with improved chromatin accessibility and neuroectodermal gene expression, and these cells successfully engrafted in rat hippocampi to ameliorate depression-like symptoms.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

This review discusses three aspects of cell fate specification across Metazoa and reports no new experimental results, highlighting the formation of nematode equivalence groups, evolution of echinoderm skeletogenic mesoderm, and adult cell fate regulation.

Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.

In this study, DNA cross-linking agents used in cancer therapy were found to cause unintended hyperplasia and fate mis-specification in normal epithelial stem cells through inflammasome activation in dermal fibroblasts.

This study found that PRC1 plays crucial roles in skin epithelial stem cell regulation, with catalytic and non-catalytic functions impacting epidermal integrity, hair development, and Merkel cell dynamics in murine models.

This review evaluates controlled studies on Platelet-Rich Plasma for androgenetic alopecia treatment, reporting positive effects on hair growth and density but highlighting the need for standardized protocols.

This study found that Sonic hedgehog signaling is crucial for Merkel cell development around hair follicles in mice, with Polycomb repressive complex 2 loss causing ectopic Merkel cells across all hair types.

In this study, researchers investigating the Drosophila testis niche system reported that Notch signaling is crucial for niche cell specification, with early gonadogenesis showing signals coming from outside the gonad to direct cell fate.

In this study, researchers observed that different ERK signal activation dynamics during hair follicle regeneration are linked to cell fate specification and are affected by distinct upstream signaling pathways.

This review highlights various methods of stem cell communication that reflect the unique organization and function of different tissues and reports no new results.

This study found that Rab5c is crucial for proper HSPC development in zebrafish embryos by regulating Notch and AKT signaling through endocytic trafficking, with both deficiency and overactivation leading to production defects.
