Notch activation in Notch1 positive feedback knock‐out intestine organoids Notch activation in Notch1 positive feedback knock‐out intestine organoids Intestine cells extracted from LGR5‐EGFP × CreERT2/Rosa26‐YFP‐NICD mice were treated with tamoxifen to induce NICD overexpression (NICD‐OE) and subsequently transfected with either an empty vector (control) or CRISPR/Cas9 gRNAs. Shown are representative brightfield images over 3 weeks. Scale bar represents 100 μm.Colony‐forming efficiency (n = 3) measured after 3 weeks. Quantitative analysis calculated from 1,000 cells/replicate.Quantitative comparison of organoid diameters (n = 5) after 3 weeks.Data information: The experiment was performed in replicates and presented mean + SD (**P ≤ 0.01, ***P ≤ 0.001; Student's t‐test compares other conditions to empty vector in normal condition separately).
