Figure 9. Changes in selected marker proteins showing changes in relative expression levels for each treatment condition. This figure expands on the immunocytochemical data presented in Figure 8 by showing the results obtained for the same seven markers under baseline proliferation (standard medium [SM]) conditions (A, D, G, J, M, P, S), as previously shown, together with the ciliary neurotrophic factor (CNTF; B, E, H, K, N, O, T) and ftela bovine serum (FBS; C, F, I, L, O, R, U) treatment conditions for comparison. Markers are listed to the left of the data, treatment above. Scale bar: 100 µm.
