Each dot on the diagram mathematically summarizes the gene expression of individual ovarian helper cells that surround developing egg cells in two-dimensional gene space. Developing cells fall ...

To investigate how the egg cell manages to rid itself of such a resilient structure, Joana Pinto, a PhD student in the Lénárt lab, developed fluorescent tags for mother and daughter centrioles ...

A gradient (red) in the concentration of the plant hormone auxin determines that only one of the eight nuclei in a plant's embryo sac will become an egg. (The blue island in the image is a cell ...

The spermatozoon has a flagellum, which is a tail-shaped structure that allows the cell to propel and move. In contrast, each egg cell, or ovum, is relatively large and non-motile. During ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. An ...

In a cell division process that is unique to egg cells, half of the chromosomes ... They predetermine the bipolar structure of the spindle that is essential to extrude exactly half of the ...

"If you take the cytoplasm of the frog egg -- note that the cytoplasm has been homogenized, so whatever spatial structure that was there has been completely disrupted -- and just let it sit at room ...
