Binding of MSC (panels A,B) or fibroblasts (panels C,D) to peptides attached to BSA was explored, as outlined in figure 1. Binding of the cells to poly-L-lysine (PLL) served as a positive contro,l and binding to unmodified BSA as a negative control. The binding patterns generated with relevant peptides (5,11,15,12,21, 22,37,57) are marked. The ordinate presents the normalized numbers of cells binding per spot on a scale from 0 to 80.
