Figure 7

Differentiated progeny of selected double-labeled daughter cells derived from 4d in C. fornicata. (A) The 4d blastomere was labeled with rhodamine dextran and the MR teloblast was subsequently labeled with rhodamine green dextran. (B-NN) The 4d blastomere was injected with rhodamine green dextran (green) at the 25-cell stage and selected progeny subsequently injected with DiI (red) at a later stage. The specific injected progeny of 4d are indicated in the lower left corner of each respective panel. Specific daughters of these double-labeled cells are indicated in each panel. For orientation, the teloblast is also pointed out on the sides containing the injected cells. A-D,L,Q,BB,EE,GG,II,LL are ventral (vegetal) views with the right side of the larvae to the left side of the figure. Views in E,F,I-J,O,T-V,X,Y,CC,MM are right lateral views. G,M,R,Z-AA,JJ are left lateral views. H,K,N,P,S,DD,HH,KK,NN are superior views taken from above the head with the right side to the right of the figure. W,FF are inferior views taken from below the foot and mouth with the right side of the larvae to the left side of the figure. Inset in R shows higher magnification view of filopodia produced by 2mL2.2. Structures are labeled as indicated in Figures 2 and 5. Scale bar in NN equals 50 μm.
