WebSomite number provides a reliable readout of developmental stage between E8 and E10.5. Although all embryos presented similar somite counts by E8.5, a significantly reduced number of somites was observed in mutant embryos by E9.5. By E10.5, the difference in somite counts between WT and KO embryos was equivalent to a 1-day lag (Figure 4D). WebTotal somite counts for Chelicerata range from a maximum of nineteen in groups like Scorpiones and the extinct Eurypterida down to seven in modern Pycnogonida. Mites may also show reduced somite counts, but reconstructing segmentation in these animals remains challenging.
