Abstract:
Dermal papilla cells (DPCs) are associated with development of hair follicles (HFs) and regulation of the hair cycle. However, primary DPCs are known to lose their ability to induce HFs after culture in standard media for fibroblasts. We examined a new culture condition for DPCs including addition of Wnt-10b, which promoted proliferation and maintained their HF induction ability for more than ten passages. These results suggest that Wnt-10b plays a pivotal role in proliferation and maintenance of DPCs in vitro.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
