Angptl5 restricts primitive hematopoiesis by modulating retinoic acid signaling in zebrafish

Purpose: Characterization of cell types in angptl5Δ10/Δ10 zebrafish. Methods: The angptl5Δ10/Δ10 embryos were raised in 0.3× Danieau Buffer and harvested at 16 hpf. Collected samples were digested with trypsin into single cell suspension for single cell sequencing. Libraries were constructed with a Chromium Single Cell 3′v3 Reagent Kit (10x Genomics) according to the manufacturer’s protocol for 7350 cell recovery.Sequencing was performed with Illumina Novaseq 6000 according to the manufacturer’s instructions (Illumina). Results: Global amplification of myeloid and erythroid progenitors in angptl5Δ10/Δ10 embryos. Conclusions: Angptl5 regulated primitive hematopoiesis in zebrafish. Collected samples of angptl5Δ10/Δ10 embryos at 16 hpf were digested with trypsin into single cell suspension for scRNA-seq.
