Fig. 7. CiYB1 protein is inherited only by the B8.11 cells, along with
Ci-PEM RNA. Embryos were stained for CiYB1 protein (magenta) and
Ci-REM RNA (green). (A-E) A 32-cell embryo; (F-J) a
gastrula embryo; (K-O) a mid-tailbud embryo. (B-E,G-J, L-O) Enlarged
views of A,F,K. (A,B,F,G,K,L) Nomarski optics. The CiYB1 protein tightly
colocalized with Ci-PEM RNA and segregated only into the B8.11 cells
(E,J,O).
