noun (plural morulae /-lē/)Embryology
A solid ball of cells resulting from division of a fertilized ovum, and from which a blastula is formed.
- That means that parents who are doing IVF could conceivably agree to have a cell removed from their morula, which could then give rise to a line of stem cells, while the morula developed into an embryo ready for implanting.
- Mammalian ova lack any overt asymmetries, and their early cleavages are simple and equal, producing a clump of cells called a morula with no discernible up, down, left, right, back, or front.
- The cells of the morula continue to divide by mitosis, and the morula passes down into the uterus.
Mid 19th century: modern Latin, diminutive of Latin morum 'mulberry'.
