Dermal Papilla Cells Serially Cultured With Wnt-10b Sustain Their Hair Follicle Induction Activity After Transplantation Into Nude Mice
Abstract:Dermal papilla (DP) cells are associated with the development of hair follicles (HFs) and regulation of the hair cycle. However, primary DP cells prepared from cultured HFs are known to lose their ability to induce HF after culturing in standard media, for example, fibroblast growth conditions. We explored a new culture condition by which DP cells maintained their HF induction ability. The addition of Wnt-10b to the first culture of primary DP cells promoted their proliferation and maintained their Wnt responsiveness and HF induction ability. Furthermore, DP cells in Wnt-10b-containing medium sustained those characteristics after 10 passages (100 days), which encompassed the entire experimental period. These results suggest that Wnt-10b plays a pivotal role in proliferation and maintenance of DP cells in vitro.

More about this publication?
- Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
