Snuppy Love

Woo Suk Hwang of Seoul National University (SNU) has succeeded in cloning a dog:

In the new study, a team led by Woo Suk Hwang of Seoul National University fused cells from an adult hound's ear to eggs obtained from fertile female dogs. Within hours after a blood test confirmed that ripe eggs had been released from a dog's ovaries, Korean veterinarians anesthetized the dog, surgically exposed her reproductive tract, and flushed the barely visible eggs into laboratory dishes.

Of about 1,400 embryos created by fusing those eggs to skin cells with an electrical shock, 1,095 were deemed healthy enough to be transferred to the reproductive tracts of surrogate mother dogs -- each of which also had to be in heat, to support the growth of those embryos into fetuses. That required more surgeries, with five to 12 embryos transferred to each of 123 surrogates.

Follow-up sonograms indicated that three of the 123 surrogate mothers were pregnant. One miscarried, and the other two gave birth. One newborn died from pneumonia after 22 days. The survivor is Snuppy, for ''Seoul National University puppy."
