This is in accordance with previous research work in which hyperglycaemia suppresses the cell cycle leading to slowing of the growth in chick embryos.10 Alteration of metabolites could be the basis of this growth inhibition as shown by work done by Moley and fellows by exposure of pre-implantation mouse embryos to elevated glucose.9 Excess glucose in mammalian post-implantation embryos resulted in ultra-structural changes in visceral yolk sac, such as reduced microvillus surface, fewer mitochondria and a sparser distribution of endoplasmic reticulum.
