Neither chlorhexidine nor hexachlorophene inhibit laminin mediated neurite outgrowth. Cerebellar granule neurons are plated on either PLL alone or PLL plus laminin (lam). The following are added to the media to give final concentrations of: ethanol (E, 25 mM), chlorhexidine vehicle (V, 1%), Chlorhexidine (CHG,1.0 μg/ml), DMSO (D, 1%) or hexachlorophene (HEX, 1 mM). Neurite length is determined as described in Figure 2. The mean of the neurite lengths for each condition is calculated, then the mean +/− SD is determined for 4 separate experiments and shown here. §p<0.005, PLL vs L1.
