Image processing and quantitative analysis. Automatic cell counting adapted from Image J Plugins (a) Overlay of the identified seeds (yellow) with tdTomato + cells. Images were presented using maximum intensity projection. (b) Validation of automatic seed identification against 50 manually identified cells. (c) The counting accuracy of 5.7% ± 3.8% in the EGFP group, and 4.4% ± 3.5% in the tdTomato group was validated by 28 randomly picked regions (a total of 7127 and 9025 cells, respectively). Error bars represent standard deviation.
