(B) Overlay of brightfield and fluorescent images prior to (top; applied strain E app =0) and after application of stretch to the endoderm (bottom; E app =0.6); endoderm nuclei are labeled by electroporation with pCAG-H2B-GFP (green). Magenta arrowheads and dashed yellow lines denote the positions of two nuclei and lateral somite boundaries, respectively. Scale bar: 100 µm. (C) Kymograph of stretch progressively applied to endoderm, illustrating concomitant deformation of somites over time. Scale bar: 100 µm. (D) Left: Schematic (top) and brightfield images (bottom) of the embryo following dorsal cuts to isolate ventral endoderm–somite interactions. Right: Comparison of Lagrangian strains in endoderm and mesoderm for control and dorsal cut embryos. ns, not significant ( P =0.52, Welch's t -test on the slopes of the strain transfer per sample). Circles represent the mean, error bars represent s.d. (E) Transverse view of fibronectin (FN; red) staining of the endoderm–somite interface of control (top) and Dispase-treated (bottom) embryos. DAPI was used to stain nuclei (gray). en, endoderm; no, notochord; so, somite. Scale bar: 10 µm. (F) Quantification of applied force versus in-plane Lagrangian strain in the endoderm for control and Dispase-treated embryos. (G) Relative stiffness quantified from the force-strain curves shown in F. * P =0.012 (Welch's t -test).
