morula

 [mor´u-lah]
a solid mass of cells (blastomeres) resembling a mulberry, formed by cleavage of a zygote (fertilized ovum).

mor·u·la

(mōr'ū-lă),
The solid mass of blastomeres resulting from the early cleavage divisions of the zygote. In oocytes with little yolk, the morula is a spheroid mass of cells; in forms with considerable yolk, the configuration of the morula stage is greatly modified.

Zhang, the lead investigator of that study, strongly suspects that the women in the day 5 group with low [beta]-hCG levels probably were receiving embryos at the morula stage.
Effects of temperature during IVM and antioxidants in embryo culture on developmental competence of embryos and cell numbers of blastocyst were analyzed by the general linear model of the SPSS 17.0 package program (SPSS, Chicago, IL, USA) after than arcsine-transformation and logl0 transformation (cleaved embryos, morula and blastocyst yields were done arcsine-transformation; cell numbers of blastocyst were logl0 transformation).
Our results indicated that immunocytes (both phagocytes and cytotoxic morula cells) are active in the transcription of genes involved in ROS detoxification, and their activity is modulated during the blastogenetic cycle and by the presence of Cd.
