- Midblastula abstract "In developmental biology, midblastula or midblastula transition (MBT) is a stage during the blastula stage of embryonic development in which zygotic gene transcription is activated. There are three major characteristics of pre-MBT embryos. Firstly, all of the embryonic cells undergo cell division at the same time. Secondly, zygotic chromatin is condensed, hypo-acetylated and H3 methylated, indicating that most of the genes are in a repressed heterochromatic state. Finally, embryos are observed to translate only maternally inherited mRNA, i.e. that mRNA which is present in the oocyte when it is fertilised. The mRNA is localised in different parts of the oocyte, so that as the embryo divides it is segregated into different cells. This segregation is thought to underlie much of the differentiation of cells that occurs after MBT. Once MBT has taken place, the embryo begins to transcribe its own DNA, cells become motile and cell division becomes asynchronous. Since the cells are now transcribing their own DNA, this stage is where differential expression of paternal genes is first observed.".
