Supplementary Figure 4: Natural variation in shape and tensions during compaction.
From: Pulsatile cell-autonomous contractility drives compaction in the mouse embryo
a–d, Mean ± s.d. are shown for the blastomeres and contacts of 3 individual embryos. Embryo shown in Fig. 1b is shown in red. a, Radius of curvature Rc over time. b, Contact angle θe over time. c, Surface tension γcm over time. d, Interfacial tension γcc/2 over time. e, Plot of each surface tension γcm of each contacting blastomeres against one another. N = 233 contacting blastomeres pooled from 28 embryos from 11 representative experiments, Pearson correlation R = 0.778 (p < 0.001). f, Plot of each contact angle θi of each contacting blastomeres against one another. N = 233 contacting blastomeres pooled from 28 embryos, Pearson correlation R = 0.603 (p < 0.001).
