Overview of all stages (More...) The unfertilized egg is surrounded by a vitelline membrane (= yolk membrane). The yolk material is distributed evenly over the cytoplasm. The sea urchin egg is …

In humans, morula stage of development occurs during the first days in week one following fertilization (GA week 3) and is described as Carnegie stage 2. This stage is followed by …

Fate map of the vegetal plate of the sea urchin embryo, looking “upward” at the vegetal surface. The central portion becomes the secondary mesenchyme cells, while the concentric layers …

In this technical report, we use a recently developed optogenetic approach to manipulate protein localization in the developing sea urchin embryo. A photosensitive LOV domain from Avena …

2020年6月1日 · Computer simulations of the early sea urchin embryo demonstrate that, i) creation of a hollow blastula from a solid morula can be accomplished by a single cell division …

The morula stage is characterized by loosely attached cells which become more closely apposed in subsequent cell divisions to result in the hollow blastula. The ciliated blastula hatches from …

Sea urchin embryos were cultured and collected for scRNA-seq analysis via DropSeq using the 10× Genomics platform. Our analysis included eight time points spanning early development, …

2012年4月1日 · Sea Urchin is one of the most useful tools in developmental biology studies because this organism has the simplest kind of developmental stages. We aimed to determine …

1977年3月2日 · Sea urchin embryo chromatin is hydrolyzed by micrococcal nuclease into a series of oligomers which are multiples of a monomer (repeating unit) containing 220 ± 22 nucleotide …

Sea urchin embryos readily take up many small molecules, including chemical inhibitors and biosynthetic precursors from the surrounding seawater. In the case of chemical inhibitors, this …
