Quantitative analysis of type I and type II neural lineages.

<p>(<b>A</b>) Frequency of divisions of type I and type II NBs, INPs and GMCs (n=29, n=31, n=6, n=6 respectively). Time measured in hours between consecutive nuclear breakdowns. (<b>B</b>) Absolute cell numbers type I and type II lineages counted after 10-hr recording period. (<b>C</b>) Nuclei volumes from all cell types of type I and type II lineages. NB type I n=30, NB type II n=31, INP n=34, GMC type I n=5, GMC type II n=6, neuron n=5. (<b>D</b>) Growth rates from birth to division of type I and type NBs, INPs and GMCs. NB type I n=30, NB type II n=34, INP n=6, GMC type I n=4) (A-D) Bars represent standard deviation. Statistical analysis done using T-test. *p<0.05; **p<0.01; ***p<0.001; ****p<0.0001. (<b>E</b>) Graphic representation of type I and type II lineages. Diameter ratios between the lineages and the different cell types is according to experimental measurements. GMC, ganglion mother cell; imINP, immature intermediate neural progenitor; mINP, mature INP; NB, NB. Red color represents nuclei, green color represents Earmuff expression.
