Abnormalities observed in cloned mice help reinforce the need to continue to avoid the reproductive cloning of humans

Dr. Takumi Takeuchi, from Cornell University, New York, USA told a media briefing that he and Dr. Gianpiero Palermo's team had compared imprinting abnormalities (the process where specific genes inherited from both parents are silent) in mice embryos derived from assisted reproduction techniques and from cloning.

Chromosomal chaos in early embryonic development is linked to abnormalities in cytokinesis and spindle formation

Abnormalities in the spindles (the bi-polar thread like structures that link and pull the chromosomes during cell division) of human embryos before implantation may be the primary reason for many of the chromosome defects observed in early human development
