CTGF/CCN2 has a chemoattractive function but a weak adhesive property to embryonic carcinoma cells

► We studied the chemotactic and adhesive roles of CCN2 to embryonic carcinoma cells. ► CCN2 showed high chemotactic effects for P19 cells. ► CCN2 is a weak adhesive molecule for P19 cells. ► We created a method to measure molecular adhesive properties under different cellular conditions.
