Numbers of cell divisions of mesenchyme cells in Tbx6-mis-expressing embryos.

<p>B7.3 and B7.7 mesenchyme blastomeres were isolated from 64-cell embryos that had been injected with control <i>H2B:mCherry</i> mRNA (gray bars) and <i>Tbx6</i> mRNA (green bars). The numbers of descendant cells were counted, and the numbers of cell divisions were then calculated. On the abscissa, e.g., 3 cell divisions represents partial embryos that divided 2.50 to 3.49 times. Numbers of partial embryos observed are indicated in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0090188#pone-0090188-g002" target="_blank">Fig. 2B</a>. Proportions of major specimens are given above the columns.
