This review discusses the function and pathology of hair follicles and highlights the potential of using dogs as a model to study human hair and stem cell disorders, but presents no new experimental results.

This study found that hair follicle mesenchymal stem cells improved liver function and pathology in a mouse model of liver cirrhosis, potentially by inhibiting the TGF-β/Smad pathway and reducing hepatic stellate cell activation.

This study found that canine hair follicle stem cells in vitro expressed markers associated with multipotency, suggesting their potential role in the hair cycle.

This study suggests that human placenta hydrolysate reduces CFA-induced inflammatory pain in mice by inhibiting pro-inflammatory cytokines and protecting peripheral nerves.

This review discusses the role of hair follicle stem cells as active signaling centers in skin homeostasis, highlighting recent advancements and reporting no new clinical results.

This study found that HIF-P4H-2 function in FoxD1-lineage cells is crucial for normal hair follicle development and homeostasis in mice, implicating disrupted HIF, TGF-β, and Notch signaling pathways in associated defects.

This study found that hair follicle stem cells from the bulge region in mice and humans can be isolated and cultured to maintain their phenotype and high proliferative capacity, suggesting their potential as an accessible source for tissue engineering and regenerative therapies.

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.
