These classic studies led to the model that division of these diploid presumptive totipotent stem cells in mother sporocysts produces progeny that are able to independently initiate the embryogenesis of daughter sporocysts (Whitfield and Evans, 1983).
The GOP is in disarray, with serious divisions between Donald Trump, the Republican presumptive presidential candidate, and much of the Republican establishment.
As previously shown (Handel et al., 2005; Handel et al., 2000), asynchronous 13th divisions occurred exclusively in the presumptive embryonic rudiment, but not in the serosa (Fig. 3E-E′′; supplementary material Movie 1).
Here, we combine theory, quantitative imaging, and perturbations to analyze how tissue geometry, cell divisions, and mechanics interact to shape the presumptive enveloping layer (pre-EVL) on the zebrafish embryonic surface.
In the family division of the high court, journalists have a presumptive right to attend hearings but have to obtain the court's agreement on whether a case may be reported and, if so, what details may be covered.
Hydractinia gastrulation occurs by mixed delamination, a combination of directed cell division and multipolar ingression to internalize cells to form the presumptive entoderm.
During the fifth nuclear division of the embryo, the E chromosomes are eliminated from all presumptive somatic nuclei [ 7].
This phase of RG division greatly expands the surface area of the cell layer lining the presumptive cerebral vesicle [9] and ultimately controls the total number of neurons in the mature cortex [10].
Chromosomal fragmentation and excision of DNA occurs at the 5th cleavage division; 12 Gb of sequence is lost from each of the 15 presumptive somatic cells during anaphase.
But chorus characters for "Presumptive"?
