The laboratory research focuses on understanding the remarkable properties of the mammalian oocyte, which exists as a highly differentiated cell type endowed with the unique capacity for creating an embryonic genome from the two terminally differentiated gamete genomes, activating that embryonic genome, and regulating its function during much of the preimplantation period. The research seeks to understand these fundamental, life-generating processes at the molecular level, by employing a combination of microsurgery, quantitative gene expression analyses, microarray analyses, and structural studies.

 

We have published a detailed study of gene expression in cloned embryos at the 1cell and 2-cell stages.The study reveals defects in regulation of maternal mRNA as well as aberrant transcription of >800 genes in clones.For more details Click Here
