This morning I found something I wrote back in May of 2000, and realized it wasn’t last year when Dolly’s arthritis was discovered, that the talk first began about her aging process. When she was born, she was born with the cell structure of a 6 year-old. Which kind of makes sense. She lived for 6 years, and the average lifespan of a sheep is 12 years. It’s nice when the math works out so nicely.
However, a few years after Dolly was cloned, there was a calf named Persephone cloned. Using a slightly different process. At the age of 1 year, Persephone still had the cell structure of a newborn. There was thought that Persephone might live longer than the average cow. That was 3 years ago.
The company that cloned Persephone is Advanced Cell Technology. I’ve been unable to find any information on her current state, but did find some pictures of some other cloned calves, along with their recent press releases.
For the classicists…here’s a picture of Persephone, drawn by Dante Gabriel Rosetti
And for the musical buffs….Here’s Streisand as Dolly:
