Ultrastructural Study on Connective Tissue-Epithelial Junctions in Anagen Hair Follicle of Human Fetus

This study found that CD90+ cells, resembling mesenchymal stem cells, are abundantly present in the lower part of anagen hair follicles in dogs.

This study found that dermal papilla and sheath cells can induce hair follicle formation in vitro and in vivo by interacting with hair follicle epithelial cells.

This study found that dermal papilla cells and dermal sheath fibroblasts can induce hair follicle formation when combined with hair follicle epithelial cells, both in vitro and in vivo in nude mice.

This study found that the volume of a hair follicle's dermal papilla is strongly correlated with its size, primarily due to the number of cells it contains and the volume of extracellular matrix.

This research observed that dermal papilla cells have the potential to regenerate hair bulbs under preferred environmental conditions when associated with dermal sheath cells or exposed to specific growth factors.

This study suggests that the attachment and interaction between dermal papillae and the hair bulb matrix are crucial for normal hair follicle growth and development in vitro.

This study found that dermal papilla cells in culture may enhance and attract follicular epithelial cell growth, suggesting their pivotal role in hair and follicle development.

This research discusses the function and culture of human dermal papilla cells, noting their unique in vitro characteristics and the ongoing efforts to understand their role in inducing hair growth.

This study found that high doses of irradiation can cause permanent hair loss in rats by destroying the epithelial elements of the hair follicle, while leaving the dermal papilla intact and capable of inducing new hair growth upon transplantation.
