  • Egg-sharing to alleviate the shortage of donor oocytes for therapeutic cloning

    We read with great interest, the recent advances in therapeutic cloning made by Hwang and colleagues (1), in which the efficiency of therapeutic cloning for the derivation of embryonic stem cells was dramatically improved. Previously, only 1 in 200 attempts were successful; now the success rate stands at around 1 in a dozen. Further rapid progress in this technology is likely, and there is a high probability of therapeuti...
