Caption: Figure 2: Example of cascades built with two daughter cells replacing each parent cell
in each new generation, for [sigma] = 0.1 (a), 0.6 (b), and 0.9 (c) over the first four generations.
In telophase 2, a second division is completed giving rise to two gametes; that is, cells with half as many chromosomes as the original parent cell
Of course, only one of the total number of alignments that could occur actually happens in each parent cell
Because the original parent cell
is replaced by the two new daughter cells, this approach ensures that stem cells will not be depleted during periods of development or healing.
If cancer cells at more than one metastatic site carry a common set of nonrandom genetic defects, it is likely that these cells are derived from a single parent cell
, says Bova.
Eventually, he says, only a "gossamer" neck connected a vacuole to its parent cell
While the duplicated DNA content is then divided between to daughter cells (identical to their parent cell
), the meiotic division is reductional, as the DNA content in the gametes is reduced to half that of the parent cell
Though previously considered to operate exclusively inside the parent cell
, it is now acknowledged that miRNAs can exit cellular boundaries and control transcription in bystander cells.
The estimates were resolved into 2m (E) x 10m (N) x 10m (RL) parent cells
for Filly SW and 2m (E) x 5m (N) x 5m (RL) parent cells
for Palomino, both of which had been sub-celled at the domain boundaries for accurate domain volume representation.
Mutation detection in parent cells
showed the heterozygote status of this mutation.
[CD34.sup.high]-enriched, [CD34.sup.low]-expressing, and parent cells
were trypsinized, filtered with 70 [micro]m cell strainer, counted, and plated in the 6-well plate (2 x 103 cells/well).
And the new neurons may get helpful heirlooms from their parent cells
, Jessberger says.
