However how tail lengths are controlled at different developmental stages has been unclear. Here we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs mice and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes.

However how tail lengths are controlled at different developmental stages has been unclear. Here we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs mice and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time polyA tail lengths of endogenous mRNAs from frog oocytes and embryos fish embryos and mouse oocytes were measured to investiage how their tail lengths were controlled.

However how tail lengths are controlled at different developmental stages has been unclear. Here we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs mice and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time polyA tail lengths of endogenous mRNAs from frog oocytes and embryos fish embryos and mouse oocytes were measured to investiage how their tail lengths were controlled.

However how tail lengths are controlled at different developmental stages has been unclear. Here we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs mice and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time polyA tail lengths of endogenous mRNAs from frog oocytes and embryos fish embryos and mouse oocytes were measured to investiage how their tail lengths were controlled.

However how tail lengths are controlled at different developmental stages has been unclear. Here we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs mice and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time polyA tail lengths of endogenous mRNAs from frog oocytes and embryos fish embryos and mouse oocytes were measured to investiage how their tail lengths were controlled.

However in most adult systems it remains elusive how stem cells assume different functional states and support spatially patterned tissue architecture. Here we dissected the diversity of neural stem cells in the adult zebrafish brain an organ that is characterized by pronounced zonation and high regenerative capacity. We combined single cell transcriptomics of dissected brain regions with massively parallel lineage tracing and in vivo RNA metabolic labeling to analyze regulation of neural stem cells in space and time. We detected a large diversity of neural stem cells with some subtypes being restricted to a single brain region while others were found globally across the brain.

concurrently. Conflicting evidence shows that cell division is either dispensable or required for formation of cell types. To determine the role of cell division in differentiation we arrested the cell cycle in zebrafish embryos using two independent approaches and profiled them at single cell resolution. We show that cell division is dispensable for differentiation of all embryonic tissues during initial cell type differentiation from early gastrulation to the end of segmentation. However in the absence of cell division differentiation slows down in some cell types and cells exhibit global stress responses. While differentiation is robust to blocking cell division the proportions of cells across cell states are not but show evidence of partial compensation. This work clarifies our understanding of the role of cell division in development and showcases the utility of combining embryo wide perturbations with single cell RNA sequencing to uncover the role of common biological processes across multiple tissues. Overall design: We arrested the cell cycle in zebrafish embryos at 6 hpf using two independent approaches: a chemical approach hydroxyurea and aphidicolin HUA and a genetic approach involving a loss of function mutation in the gene emi1 allele hi2648. We tracked differentiation dynamics using single cell RNA sequencing scRNA seq on embryos spanning 6\u201324 hpf for HUA treated and control embryos and at 24 hpf for emi1 mutant embryos. Overall we have collected multiple replicates for control embryos ABs at 6 8 10 14 18 21 hpf and 24 hpf for HUA treated at 8 10 14 hpf and 24 hpf and for emi1 mutants at 24 hpf.

We show that cell division is dispensable for differentiation of all embryonic tissues during initial cell type differentiation from early gastrulation to the end of segmentation. However in the absence of cell division differentiation slows down in some cell types and cells exhibit global stress responses. While differentiation is robust to blocking cell division the proportions of cells across cell states are not but show evidence of partial compensation. This work clarifies our understanding of the role of cell division in development and showcases the utility of combining embryo wide perturbations with single cell RNA sequencing to uncover the role of common biological processes across multiple tissues. Overall design: We arrested the cell cycle in zebrafish embryos at 6 hpf using two independent approaches: a chemical approach hydroxyurea and aphidicolin HUA and a genetic approach involving a loss of function mutation in the gene emi1 allele hi2648. We tracked differentiation dynamics using single cell RNA sequencing scRNA seq on embryos spanning 6\u201324 hpf for HUA treated and control embryos and at 24 hpf for emi1 mutant embryos. Overall we have collected multiple replicates for control embryos ABs at 6 8 10 14 18 21 hpf and 24 hpf for HUA treated at 8 10 14 hpf and 24 hpf and for emi1 mutants at 24 hpf.

G2/M phase arrest was induced by crossing heterozygous emi1 wt/mut zebrafish to generate homozygous emi1 mut/mut embryos referred as hi2648 in the manuscript. Homozygous mutants with cell cycle arrest were screened at 24 hpf as they have very clear phenotype by this time \u2013 these embryos are smaller and have bent tails and the heterozygous mutants and wildtype are indistinguishable.", "Zebrafish embryos were dechorionated using 1mg/mL Pronase Sigma P5147 1G for 5 7 minutes followed by washing in egg water. Embryos were dissociated as previously described in Wagner et. al. Science 2018. Briefly embryos were dissociated in 0.5mL LoBind microcentrifuge tubes that had been precoated with 10% w/v BSA for about 15 minutes at room temperature. They were homogenized in 1XDPBS/1% w/v BSA for 6 hpf to 10 hpf embryos early time points and in 500 \u00b5L FACSmax cell dissociation solution Genlantis T200100 for 14 hpf to 24 hpf embryos late time points. Cells were then filtered through a 40\u00b5m cell strainer mesh Fisher 352340 and centrifuged in a swinging bucket rotor at 200g for 1 minute early time points or 300g for 5 minutes late time points. Cells were then washed in 1XDPBS/1%BSA using the same centrifuge settings. They were then resuspended in 1XDPBS/0.5%BSA/18% optiprep density medium Sigma D1556 250ML. Cell concentration was manually quantified using hemocytometer and adjusted to a final concentration of 100 000 cells/mL before encapsulation.

Zebrafish mutant line hi2648 a mutant for the gene emi1 was kindly gifted by Dr. Jennifer Rhodes. Embryos were developed within the ambient temperature of Zebrafish development. Time of fertilization at 28.5 C was used to stage each clutch and this was confirmed using morphological features of the embryos.
