Generation of reporter knock-in CRXp-tdTomato cell line. a Schematic diagram showing the targeting strategy of the insertion site. tdTomato cDNA sequence was fused in-frame into CRX behind start codon. b Overall 3D organoids fluorescent and bright field images on D45, D60, D90, and D120. A typical fluorescence intensity increasement along with differentiation time is presented. c Representative flow cytometry analysis in D45, D60, D90, and D120 organoids. Black and red represent the organoids derived from control and knock cell line, respectively. d Overall fluorescence intensity of organoids quantified by ImageJ, data are presented as the mean ± SEM (n = 27, 14, 11, and 10, respectively). e Proportion of tdTomato-positive cells in 3D organoids counted by flow cytometry, data are presented as the mean ± SEM (n = 6, 6, 8, and 3, respectively). f Comparison of increasement tendency between flow cytometry analysis and fluorescence intensity. g Relationship between fluorescence intensity and the number of tdTomato-positive cell in 3D organoids
