Figure 2

(a) Effect of NAT-NGF and LBD-NGF on neurite outgrowth in PC12 cells. (b) Effect of NAT-NGF and LBD-NGF on cell survival in PC12 cells by MTT assay. (c) Percentage of PC12 cells with neurite outgrowth on laminin stimulated by NAT-NGF and LBD-NGF. (d) PC12 cell survival on laminin stimulated by NAT-NGF and LBD-NGF was determined by MTT assay. n = 6, *, P<0.05, **, P<0.01, determined by two-tailed student's t-test.
