The tissue from a Russian mammoth carcass is to be used by a team from Japan to clone a mammoth. According to the leader of the team, Akira Iritani "Preparations to realize this goal have been made".
The nuclei of mammoth cells will be used to replace the nuclei of an elephants egg. The embryo will be planted in a elephant´s uterus in hopes that it will developed to a full term mammoth.
The mammoth walked the earth during the last "Ice Age".
The problem with cloning was successfully using nuclei from frozen cells. The team will use technique developed by Teruhiko Wakayama of the Riken Centre for Developmental Biology. Wakayama´s method cloned a mouse from tissue frozen for 16 years.
