Sulfated polysaccharide capable of binding to growth factor and use thereof

Abstract

A biological substance which can enhance the proliferation and differentiation of cells; a method for evaluating the proliferation and differentiation of cells, which targets the biological substance; a composition for detecting the proliferation and differentiation of cells, which contains a molecule capable of binding to the biological substance; and a composition for enhancing the proliferation and differentiation of cells, which contains the biological substance. A part of a sulfated polysaccharide secreted from cells binds to a growth factor during the course of the proliferation and differentiation of the cells, that the amount of the sulfated polysaccharide capable of the above-mentioned binding and secreted from the cells correlates strongly with the progression of the proliferation and differentiation of the cells, and that the proliferation and differentiation of cells can be evaluated and the proliferation and differentiation of cells can be enhanced utilizing the sulfated polysaccharide.
