7C Definition of maternal spindle transfer
Maternal spindle transfer is a technique that involves taking the following steps, without intentionally modifying any nuclear DNA or mitochondrial DNA: (a) removing the maternal spindle from a human egg (egg A) of a woman; (b) removing the maternal spindle from a human egg (egg B) of a different woman; (c) implanting into egg B the maternal spindle removed from egg A, while seeking to minimise carryover of mitochondria from egg A to egg B; (d) fertilising egg B with a human sperm to create a zygote.
