Fig. 3From: Mechanical stretching boosts expansion and regeneration of intestinal organoids through fueling stem cell self-renewalStretching induced crypt hyperplasia. a Immunostaining for β-actin. b Statistical analysis for the number of crypt fission. c Haematoxylin and Eosin-staining. The statistical data represent mean ± s.d. (n = 30 organoids derived from three independent experiments for each condition). Student’s t-test: ***P < 0.001. **P < 0.01. *P < 0.05.
