This study found that umbilical cord mesenchymal stem cell-derived exosomes improved hair growth in mice with androgenetic alopecia by promoting hair follicle stem cell stemness through the RAS/ERK pathway, suggesting a potential new treatment strategy for this condition.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

In this study, researchers using a Treg-specific HuR-deficient mouse model found that the RNA-binding protein HuR is crucial for stabilizing Foxp3 mRNA, affecting Treg function and immune regulation, with HuR disruption leading to impaired Foxp3 expression and potential autoimmune dysfunction.

This study identified proteins that are differentially expressed in balding versus non-balding dermal papilla cells, potentially aiding the understanding and treatment of androgenetic alopecia.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.

This review summarizes discussions from a 2010 stem cell biology meeting, covering the origin, behavior, and therapeutic potential of pluripotent and multipotent stem cells, without reporting new experimental findings.

This study found that glycolytic metabolism and lactate production are crucial for hair follicle stem cell activation, and manipulating these processes can stimulate the hair cycle.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

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 study highlights that the mammalian target of rapamycin complex 2 (mTORC2)-Akt signaling axis is essential for hair follicle stem cells to return to their niche and regenerate effectively by regulating metabolic pathways.
