TREND-O-RAMA: UDDER NONSENSE...
...Brand Milk Products gathered up some of these cells and gave them the Dolly-the-sheep treatment: transplanting their DNA into hollowed-out eggs and inserting the resulting embryos into the wombs of surrogate cows. Mammary cells were also used to produce Dolly, but they were scraped from the udder of an adult sheep. The Japanese scientists believe their kinder, gentler technique will make it easier to clone high-milk-yielding "supercows" by reducing the risk of bacterial infection in valuable parent animals...
Running while in a costume was a challenge for some students. Benjamin M. Miller '02, who came in second place among men, said it was easier to take off as a cow was probably slowed by a full bodysuit--which had large udder attached--Malan saidit didn't matter...
...create Dolly, the Roslin team concentrated on arresting the cell cycle--the series of choreographed steps all cells go through in the process of dividing. In Dolly's case, the cells the scientists wanted to clone came from the udder of a pregnant sheep. To stop them from dividing, researchers starved the cells of nutrients for a week. In response, the cells fell into a slumbering state that resembled deep hibernation...
...Roslyn Institute in Edinburgh, Scotland, will publish a report on the sheep cloning Thursday in the journal Nature. Previously, scientists had cloned less complex life forms, like tadpoles, but the tadpoles had never developed into frogs. In the sheep experiment, tissue was taken from the ewe's udder and cultivated in a lab, using a process that rendered the cells essentially dormant. They also took unfertilized sheep eggs, removed the nucleus, and then fused them with cells from the udder. The eggs, now equipped with a nucleus, grew into embryos as though they'd been fertilized. The embryos were then...
