According to Official Guinness Records,
In October 2001 a team of scientists at Advanced Cell Technologies (Massachusetts, USA), led by Dr Jose Cibelli (USA), created the first cloned human embryos using a cumulus cell from a mature human egg. One of these embryos managed to divide into six cells before growth ceased after around five days. The research aims to eventually produce cloned stem cells for use in curing disease.
