Additive effects of LIF, BDNF, and NT-3 on neurogenesis. Quantification of the fraction of TuJ-expressing cells of the total number of cells treated with LIF and different combinations of neurotrophins. The analysis was done after a 10-day differentiation period. LIF was used at 10 ng/ml, BDNF and NT-3 at 50 ng/ml, and NGF at 20 ng/ml. Error bars indicate S.E.M., * indicates p < 0.05, ** indicates p < 0.01, n = 3.
