Segregation During Ascidian Embryogenesis of Egg Cytoplasmic Information for Tissue-Specific Enzyme Development
Open accessAbstract
Cleavage-arrested embryos of the ascidian Ciona intestinalis were able to differentiate two tissue-specific enzymes—muscle acetylcholinesterase (EC 3.1.1.7) and brain pigment cell tyrosinase (EC 1.10.3.1). Cytochalasin B, colchicine, Colcemid, and podophyllotoxin were used as cleavage inhibitors at early embryonic stages up to the 64-cell stage. Only certain cells in the cleavage-arrested embryos developed these histochemically detectable enzymes, and this ability followed the cell lineage patterns for the two tissues. This result implies the presence of specific positional information in the egg cytoplasm that is differentially segregated during cleavage. There were distinct and separate puromycin and actinomycin D sensitivity periods for the occurrence of each enzyme during development of both normal and cleavage-arrested embryos. The segregated information is apparently neither the enzyme proteins nor RNA templates for enzyme synthesis, but is probably concerned with activation of appropriate genes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
