I haven't been able to use my Sandbox for whatever reason (I'm technologically challenged I guess that's enough of a reason).

Original: Epiboly is a cell movement that occurs in the early embryo, at the same time as gastrulation. It is one of many movements in the early embryo that allow for dramatic physical restructuring (see morphogenesis). The movement is generally characterized as being a thinning and spreading of cell layers. Epiboly has been most extensively studied in zebrafish as their development allows for an easy visualization of the process.

Rewrite: Epiboly describes one of the five major types of cell movements that occur in the gastrulation stage of embryonic development of some organisms. Epibolic movement specifically is the way in which a layer epithelial cells spreads, and this can be achieved in multiple ways. When undergoing epiboly, a monolayer of cells must undergo a physical change in shape in order to spread. Alternatively, multiple layers of cells can also undergo epiboly as the position of cells is changed or the cell layers undergo intercalation. While humans embryos do not experience epiboly, this movement can be studied in sea urchins, tunicates, amphibians, and most commonly in zebrafish.
