Sea urchin primary mesenchyme cells (PMCs) ingress into the blastocoel during an epithelial-to-mesenchymal transition (EMT), migrate along the blastocoelar wall for a period of time, and then settle into a subequatorial ring to form the larval skeleton. Fluorescent-marked blastomeres alone, or in combination with blastomere recombination, were used to track the position of PMCs during the early phases of this movement. Micromeres expressing Golgi-tethered GFP (galtase-GFP) were transplanted… CONTINUE READING
