maturation

 [mach″u-ra´shun]
1. the stage or process of attaining maximal development; attainment of maximal intellectual and emotional development.
2. in biology, a process of cell division during which the number of chromosomes in the germ cell is reduced to half the number characteristic of the species.

mat·u·ra·tion

(mat'yū-rā'shŭn),
1. Achievement of full development or growth.
2. Developmental changes that lead to maturity.
3. Processing of a macromolecule, for example, posttranscriptional modification of RNA or posttranslational modification of proteins.
4. The overall process leading to the incorporation of a viral genome into a capsid and the development of a complete virion.

In addition to the nuclear maturation, oocytes experience the cytoplasmic maturation, including rearrangement of many organelles, cortical granules, for fertilization process (Voronina et al., 2003).
Significance: In-vitro maturation is a very useful method because it has the potential to collect a large number of oocytes from an ovary of dead or slaughtered animal.

Results: No significant difference existed between the maturation rates in [alpha]-MEM (68.18%) and ESCM (64.67%; p>0.05), whereas this rate was significantly higher for both [alpha]-MEM and ESCM compared to ESGM (32.22%; p<0.05).
