| Research Abstract |
Eggs of Oikopleura (Appendicularia, Tunicata) build a functional juvenile body in the shortest time period and with the least number of cells among chordate organisms. We aimed to comprehend all the cell divisions, cell positions, and the differentiation status from cleavage stage to juvenile stage in Oikopleura development using live-imaging and genetic techniques. Our effort in this study established reliable markers that can track nuclei and plasma membrane, and discovered a subcellular apparatus in cleavage staged embryos that is involved in pulling the nucleus before the cytokinesis to make an unequal cleavage.
