Nuclear Reprograming
Animal Genetics
Research Overview   Since the last 20 years we have focused on understanding the process of cytoplasmic inheritance. We have successfully created animal models to study mtDNA inheritance, and its related cell death process during early embryo development, which allowed us to develop a patent on SCNT animal production. We also dedicated to understand the process of cytoplasmic inheritance and its effect on nuclear reprograming, especially on the imprinting modifications after in vitro manipulation such as cloning or reprograming somatic cells.
Recently we developed an interesting method for depletion of specific organelles or compounds in oocytes, zygotes or cells that allowed us to test for their effect on embryogenesis and to introduce other organelles or compounds (we did it on mitochondria and we are now testing on lipid granules) in order to partially control their inheritance. Within the next 11 years, we will together with the CTC group continue to work on this area willing to evaluate the production of reprogrammed cells to autologous cell therapy and to control the cytoplasmic inheritance in order to apply to cell based therapy.
