Sentence examples for clonal divisions from inspiring English sources

A hypothetical 10% contaminant subpopulation in the sorted caspase3hi population would have to proliferate more than 50-fold (∼5.5 clonal divisions) in 24 h to overtake the culture completely; a highly unlikely scenario given the calculated rates of division of CD8+ T cells during their peak proliferative phase (∼3 divisions) [3], [25].

Altogether, B. henselae isolates were found to be distributed within 3 distinct lineages (Marseille, Houston-1, and Berlin-2), and the 16S rRNA gene was not a sensitive marker of the clonal divisions of B. henselae.

This strongly indicates that clonal division is not required for the formation of aggregates.

Here, we studied a plant that propagates by clonal division and can undergo dormancy without forming seeds.

Multicellular organisms evolved through two major strategies: aggregation of different cells or clonal division of a single cell.

Second, gene drives cannot affect species that exclusively practice asexual reproduction through clonal division or self-fertilization.

Another curiosity of ciliates, the amitotic divisions of macronuclei making daughter cells from a clonal division potentially have slightly different alleles or amounts of alleles ([ 78], reviews by [ 75, 76]) did not invalidate our study.

DOI: http://dx.doi.org/10.7554/eLife.01287.006 To investigate whether C. owczarzaki cell clusters are formed through aggregation or clonal division, we first mixed two differentially stained populations of cells ('Materials and methods') and induced aggregate formation, resulting in dual-colored cell clusters.

Some of these inadequately supported assertions are: 1) that colonies form through aggregation A major argument that colonies form by aggregation rather than clonal division is that the aggregates are detected within a few hours, whereas the doubling time of a normal culture during exponential growth is approximately 24 hours.

10.7554/eLife.01287.009 Figure 4. C. owczarzaki cell clusters form by active aggregation, not clonal cell division.

Overall, these results show that C. owczarzaki cell clusters form by active cell aggregation, not by clonal cell division.
