Analysis of murine embryos. (a) Compaction-stage murine embryos consisting of eight cells were imaged such that cells were nominally 120 pixels in diameter, and had on average 18 sections through each cell (scale bar, 10 µm). Tensions measured using micropipette aspiration at time A (90 min after the last division from four- to eight-cell stage) are shown in (b) and those at time B, 150 min later, in (c). CellFit-3D inferred tensions have been scaled so that their average value is the same as that of the values from the pipette aspiration experiments. Error bars on the experimental values are ±10% (see §4) while CellFIT-3D tensions show their respective standard errors. In this figure, only, tension errors are with respect to aspiration experiments not ground truth.
