Single-cell transcriptional dynamics in a living vertebrate

Elizabeth Eck,
Bruno Moretti,
Brandon H. Schlomann
et al.

Abstract: The ability to quantify transcriptional dynamics in individual cells via live imaging has revolutionized our understanding of gene regulation. However, such measurements are lacking in the context of vertebrate embryos. We addressed this deficit by applying MS2-MCP mRNA labeling to the quantification of transcription in zebrafish, a model vertebrate. We developed a platform of transgenic organisms, light sheet fluorescence microscopy, and optimized image analysis that enables visualization and quantification o… Show more

“…In contrast, in short wavelength patterns mobility increases phase variance due to steep phase gradients. Recent imaging of mRNA and protein cycles at single cell level in the embryo [14,16] may open the road to test these predictions.…”

“…1B) [13,14]. The difference in oscil-lation frequency results in traveling phase waves across the anterior-posterior axis of the segmenting tissue, as revealed by protein [15] and mRNA expression [16]. A new segment boundary is determined when a wave comes to the anterior part of the tissue [17,18].…”
