Zebrafish embryos were further digested in PBS containing 0.25% liberase at 28\u00b0C for 5 minutes and a single cell solution was prepared by passing through a 40\u03bcm nylon mesh. Both GFP positive and negative single cells were sorted into Trizol LS reagent Life Technologies  respectively with a BD FACSAria Cell Sorter BD Biosciences.  RNA was extracted using a Direct zol RNA extraction kit Zymo research. RNA Seq libraries were prepared from purified total RNA using a modified Smart Seq2 protocol developed by Picelli et al. 55. 2 ng of purified total RNA 0.4 ng/\u00b5L was combined with 1 \u00b5L of 10 \u00b5M oligo dT primer /5Biosg/AAGCAGTGGTATCAACGCAGAGTACT30VN; Integrated DNA Technologies and 1 \u00b5L of dNTP mix 10 mM each; Invitrogen  y02256  then the protocol was continued as described ref. 2. Briefly  the RNA was reverse transcribed with the Smart Seq2 TSO /5Biosg/AAGCAGTGGTATCAACGCAGAGTACATrGrGrG  Integrated DNA Technologies  followed by 12 cycles of PCR amplification to obtain enough cDNA to prepare a library. Volumes of reagents were scaled accordingly to maintain final concentration ratios as in the original protocol  except for the PCR preamplification where the Smart Seq2 ISPCR primer /5Biosg/AAGCAGTGGTATCAACGCAGAGT; Integrated DNA Technologies was added to a final concentration of 0.25 \u00b5M. 0.5 ng of cDNA was prepped into a library using the Nextera XT DNA Library Prep Kit Illumina  FC 131 1096  with 12 cycles of PCR used to amplify the final library. The final Nextera XT libraries were quantified on the Perkin Elmer LabChip GX with the DNA High Sensitivity Reagent kit Perkin Elmer  CLS760672.
