Table 2. Cell shape, size, and filopodia comparison between embryonic and extra-embryonic mesoderm.

P values were calculated using the Mann–Whitney–Wilcoxon for surface, long/short axis and filopodia/cell/time point and the t test for volume, and filopodia length. Data can be found in Figure 2—source data 2 and 3.

	Volume (μm3)		Surface (μm2)		Long/short axis			Filopodia/cell		Filopodia length (μm)
