A Fresh Attmpt To Clone Mammoths
Since the nuclei taken from skin and muscle tissues from mammoths found in the Siberia were badly damaged, earlier efforts in the 1990s to clone mammoths had failed.
But in 2008 Dr. Teruhiko Wakayama, working at the Riken Centre for Developmental Biology, was successful in cloning a mouse using a technique developed by him, by using skin cells of a mouse that had been frozen for over 16 years. Based on this approach, Akira Iritani, a professor working at Kyoto University, is planning to clone and resurrect the mammoths that became extinct about 5,000 years ago. He plans to identify a relatively good sample of soft tissue from a frozen mammoth for the above purpose. He is planning to apply Dr Wakayama’s techniques to obtain the nuclei of viable mammoth cells before proceeding to extract the healthy cells.
He further plans to insert the nuclei into the egg cells of an African elephant, which will then become the surrogate mother of the mammoth. It may well take over two years before reaching the stage of impregnating the elephant. The gestation period is about 600-days. With improvement in cloning cattle being successful up-to 30%, the chances of obtaining a cloned mammoth looks bright in the coming four to five years.
