Abstract
A method for preserving proliferation and differentiation potential of undifferentiated cells, has steps of providing a culture carrier having a surface coated with a biological material selected from the group consisting of hyaluronan, chondroitin sulfate, carboxymethyl cellulose, carrageenan, alginate, and chitosan; and inoculating and culturing the undifferentiated cells on the surface in the culture carrier with an appropriate medium, such that the proliferation and differentiation potential of undifferentiated cells are preserved. The method can be used for expanding stem cells in vitro without loss of their replicative ability and differentiation capacity. Therefore, the method according to the present invention is amenable to application in regenerative medicine, tissue engineering, and therapy using umbilical cord blood and other cell sources such as peripheral blood, stem cells, tissue progenitor cells, and tissue cells.
