The first event during the sexual cycle is "meiosis", scored by observation of MIC division at different stages of meiosis I and II.
Thus, it is possible that participants in our studies allocated attention on an all-or-none basis on each trial, and that our observation of flexible division actually reflects a different mixture of all-or-none states in each combination of reward conditions.
Direct observation of cell divisions enabled the complete reconstruction of the lineage tree of somatic cells of Caenorhabditis elegans [2], [3], yet this method is inapplicable to humans and mice since they are opaque and have a tremendous number of cells [4].
On the other hand, the results from the observation of vertical divisions induced by mouse Inscuteable overexpression support the idea that the basal domain of the mother cell is also important in maintaining progenitor properties (Konno et al. 2008).
Both prize-winning technologies are now used every day the world over in biology and medicine, for myriad purposes, including studies of the creation of synapses in nerve cells; the tracking of proteins involved in diseases such as Parkinson's, Alzheimer's, and Huntington's; and observations of the division of fertilized eggs.
For the observations of cell division slides of the media mentioned above were used with 2% agar.
We did not follow P cell division because we found that observation of P cell divisions was extremely difficult due to the roller phenotype of the animals.
For the observation of changes in cell division, ten root tips were squashed in Carbol Fuchsin solution [ 64].
The obvious observation of cell migration and division prove the viability of the cells, supporting the high biocompatibility of our technique.
The observation of cell cycle and cell division related gene expression, altered by endoreduplication, was suggested to play a role in the maintenance of the single-celled structure of seed hairs.
