Figure 6From: Mef2A, a homologue of animal Mef2 transcription factors, regulates cell differentiation in Dictyostelium discoideumIn vitro differentiation of wild-type and mef2A-mutant cells into spores. Wild-type (AX4) and mef2A- mutant (mef2A-) cells were incubated in the presence of Br-cAMP, a cell-permeable derivative of cAMP, to induce spore differentiation. Pictures were taken after 30 hours of incubation using a TS100 Eclipse Nikon microscope. Scale bar: 10 μm.Back to article page
