Fig. 6.
Effect of the α4(V) NTD and pepsinized collagen type V on Schwann cell adhesion. Schwann cells were plated on dishes coated with the indicated ECM proteins and incubated for 3 hr in serum-free medium with heregulin. Schwann cell adhesion was measured by the crystal violet assay. IV, Collagen type IV;pep. V, pepsinized collagen type V; Ln, laminin. Values that are significantly different from collagen type IV or laminin alone are indicated (*p < 0.05; **p < 0.01). Note that the value for pepsinized collagen type V plus the NTD is not significantly different from that of the NTD alone.
