Fig. 9. Ch-Ac and Ch-Sm do not support full development to fruiting bodies. AX3 cells developed to fruiting bodies; HS1 never progressed beyond the mound stage; Dd-Wt rescued full development in HS1 cells; HS1 cells expressing Ch-Ac did not develop beyond the mound stage; Ch-Sm-transfected HS1 cells developed a few aberrant fingers but never developed to fruiting bodies. All micrographs were taken at 48 hours after plating the amoebae.
