While genome wide techniques such as RNA sequencing are ideally suited for discovering novel candidate genes  they are unable to yield spatially resolved information in embryos or tissues. Microscopy based approaches  using for example in situ hybridization  can provide spatial information about gene expression  but are limited to analyzing one or a few genes at a time. Here  we present a method where we combine traditional histological techniques with low input RNA sequencing and mathematical image reconstruction to generate a high resolution genome wide 3D atlas of gene expression in the zebrafish embryo at three developmental stages. We also demonstrate that our technique is suitable for spatially resolved differential expression analysis in wildtype and Gli3 mutant mouse forelimbs. Importantly  our method enables searching for genes that are expressed in specific spatial patterns without xxx image annotation.

We describe Tdrd6a as a component of these structures with two distinct molecular functions. First  Tdrd6a facilitates the accumulation of the typical antisense bias of piRNAs  without xxx effects on piRNA biogenesis signatures. Second  we show that Tdrd6a is required for Balbiani body and germ plasm integrity  and associates with RNA binding proteins and germ plasm mRNAs. On the cell biological level  maternally contributed Tdrd6a strongly impacts germ cell formation  but is dispensable for fertility. Using single cell RNA sequencing we demonstrate that Tdrd6a promotes early germ cell development and regulates the stoichiometry of germ plasm mRNAs.
