Under the microscope, the embryologist counted several morulae before proceeding to blastocyst culture.

Under the microscope, the embryo reached the morula stage, a spherical mass of blastomeres that forms after the zygote splits.

During the lab session, we observed several morulas under the microscope and noted differences in cell compaction.

Scientists observed sperm morulae under the microscope to study early fertilization stages.

Scientists observed a rapid shift in microbial populations within the sperm morula during early seed germination.

The pathologist identified a morula cell among the plasma cells in the bone marrow biopsy.

Researchers stained morula cells to observe how they differentiate during early embryonic development.
