23 Jul Conspecific variant fat stem cell used as tissue engineering seed cell
Abstract
The invention provides a kind of fat stem cells of multi-directional differentiation function and the induction method of preparing stone, cartilage and fat. It expresses HLA I, not CD80, CD86, CD40, CD28, while after the reaction of hIFN-gamma , the expression of HLA I doesn’t increase obviously. Such cell has less immunogenicity, a certain function of immunological regulation, no obvious change with the action of hIFN-gamma . The fat stem cells of bone, cartilage and fat induction have the same function with previous induction, and no obvious change after hIFN-gamma reaction.
