Stereotyped early cleavages in glossiphoniid leech embryos yield 25 micromeres, along with 3 macromeres and 10 teloblasts. The micromeres generate prostomial tissues and also give rise to most of the squamous epithelium of a provisional integument that spreads epibolically from the animal pole, covering the rest of the embryo during germinal plate formation.We systematically injected individual micromeres with fluorescent cell lineage tracers at the time of their birth and quantitatively mapped… CONTINUE READING
