Abstract:
Objective To investigate the actions of extra cellular medium in growth and differentiation of hair follicle and to look for growth adjusting factors for dermal papilla cells (DPC). Methods Dermal papilla cells were isolated and cultivated with two steps method and the cells were identified by immunohistochemical staining for actin. Influence was examined on the adhesion and growth of dermal papilla cells by chondroitin sulfate A, chondroitin sulfate C and heparin sulfate. Results Two steps method of enzyme digestion for isolating and cultivating dermal papilla cells was an efficient method and large amount of dermal papilla of high purity were harvested with this method. The method is very simple and easy to manege with. Increased adhesion and growth of dermal papilla cells were observed in specimen treated with chondroitin A and heparin sulfate. No significant effects was observed in the cells treated with chondroit in sulfate C. Conclusion Some extra cellular medium can regulate the adhesion and growth of dermal papilla cells and therefore influence the growth and development of hair follicle.
