Embryos were cultured in filtered (0.2micron) sea water collected at the Marine Biological laboratories in Woods Hole MA, until the appropriate stage for dissociation (48 and 72 hours post fertilization). To test the function of gcm, eggs were dejelled before fertilization by washing in pH4.0 seawater, and injected post fertilization in presence of 1mM 3-AT with either a control morpholino or the gcm morpholino used at a concentration of 0.5mM. The resulting wild type controls and albino embryos were collected at 48 hpf. These 4 samples (non injected 48 and 72 hpf, control morpholino injected 48 hpf and gcm morpholino injected 48 hpf embryos) were used for single cell RNA seq.
