Fig. 9. Differentiation of OBSC into dopaminergic and mitral/tufted neurons. (A-D) Representative images of MAP2ab⁺ and Th⁺ cells in differentiating E13.5 OBSC cultures. (E) Average percentages of Th⁺ neurons relative to total MAP2ab⁺ neurons. Results are the mean±s.e.m. of data from four cultures in two experiments. Scale bar: in D, 40 µm. (F) Average percentages of Tbr1⁺ vs total MAP2ab⁺ neurons. Bdnf-treated cultures had 26% more Tbr1-labeled cells than controls (not statistically significant). Results are the mean±s.e.m. of data from four to six cultures in three experiments. (G-J) Representative images of MAP2ab⁺ and Tbr1⁺ cells. Arrows show Tbr1⁺ nuclei in the neurons. Scale bar in J: 50 µm.
