| (Latin, ''morula'' = mulberry) An early stage in post-fertilization development when cells have rapidly divided to produce a solid mass of cells (12-15 cells) with a "mulberry" appearance. This stage is followed by formation of a cavity in this cellular mass [[blastocyst]] stage.
| |
| | |
| In humans, morula stage of development occurs during the first days of the first week following [[fertilization]]. This developmental stage is followed by formation of a cavity, the blastocoel, which defines formation of the [[blastocyst]].

By examining a large set of zygotes from in vitro fertilization (IVF), we find that success in progression to the blastocyst stage can be predicted with >93% sensitivity and specificity by measuring three dynamic, noninvasive imaging parameters by day 2 after fertilization, before embryonic genome activation (EGA)."
