Andrew Tiedemann, a spokesperson for the University Development Office, points out that it has been 12 years since the last campaign started and thus since Harvard development officials last tried to solicit so-called “nucleus fund” donors...
...scientists' basic strategy was the same as in most post-Dolly cloning experiments: remove the nucleus of the egg, with its single set of chromosomes, and replace it with the nucleus of a mature cell, containing two sets (in this case, the mature nuclei came from cumulus cells, which surround eggs during development). With a quantity of eggs that a commentary in Science calls "whopping," the scientists were able to experiment with different techniques to find which worked best--varying the time between inserting the new nucleus and zapping it with electricity to trigger cell division, for example, or testing...
...Korean team believes that two other factors may have helped them succeed. While most cloners suck out an egg's nucleus with a tiny pipette, Moon and Hwang made a pinhole in the cell wall and used a tiny glass needle to apply pressure and squeeze the nucleus out. "It's more gentle with the egg and allows you to remove only the DNA and leave some of the major components of the egg still inside," says Jose Cibelli, a professor of animal biotechnology at Michigan State University and a co-author of the Science paper. "Actually, it's pure...
