Fig. 5. Kinetics of neurite outgrowth on neutral and acidic laminin matrices. Cells
were plated onto neutral (open symbols) or acidic laminin matrices (closed
symbols) and fixed after 2, 6, 16 or 24 hours. After immunostaining for Tau,
the average sizes of the 30 longest neurites were averaged and plotted against
the time of incubation. Inset shows the absence of cell clumps within 2 hours
of plating on the neutral matrix.
