The figure below shows a blastula stage Xenopus laevis embryo (left) that has been separated into animal and vegetal halves. The different colors represent the three germ layers derived from the cell tiers. The figures on the right show two embryological manipulations that have been done where a dissected animal cap (arrow in figure on the left) has been removed from a normal embryo and recombined with different vegetal blastomeres as shown in the figure. Tier D indicates the future dorsal side of the embryo. These explants are cultured and then analyzed using molecular markers for epidermis, neural cells, endoderm, blood, and notochord when control animals are at the tadpole stage. The questions below are based on this experiment. (Explant consists of animal cap + vegetal cell descendants). What are the molecular markers that are expressed in embryo explants where an animal cap is recombined with the vegetal blastomere labeled 1? Please consider all the markers listed above.
