Quantitative Description of Surface Cell Shape Change of Zebrafish Embryos

(A) Schematic illustration of simplified epithelial monolayer, gray indicates the free surface, cell shape is represented by aspect ratio L/R.

(B) The morphology of an epithelial layer is represented as a distribution of L/R ratios.

(C) Zebrafish enveloping layer (EVL, blue) in the context of the whole embryo. Sketch represents a lateral cross-section of an oblong (~4 k cell) stage embryo.

(D) Time-lapse imaging data and measurement of surface cell L/R ratios (dashed cyan lines). Scale bars represent 20 µm. See also Figures S1D–S1H.

(E) Morphogenesis of surface layer over five cell cycles. n = 860. Inset: average L/R ± SD.

(F) Morphogenesis of deep layer over five cell cycles. n = 200. Inset: average L/R ± SD. The variance of ln(L/R) of deep cells is smaller than that of surface cells (f tests).
