SCNT (somatic cell nuclear transfer) is a technique in which the genetic material from an egg cell is replaced with that of an adult or embryo body cell of the same animal species. Also known as cell nuclear replacement (CNR), or popularly as 'cloning'.
Scientists at Stanford University in the US have discovered the key ingredient that triggers development in the newly fertilised egg. Their findings, published in the journal Nature last week, could lead to new treatments for male infertility. The researchers studied egg and sperm from sea urchins, and found that upon...
A cloned cow has given birth to a healthy female calf at the Ishikawa Prefectural Livestock Research center in northern Japan, Japanese government officials announced last week. Other cloned mammals - including Dolly the sheep - have already reproduced, but this is the first reported case of a cloned cow breeding successfully...
The first goat to be cloned using an adult cell died last week, shortly after being born. The goat, called Yuanyuan, was cloned by a team of Chinese scientists using somatic cell nuclear transfer - the 'Dolly technique'. The researchers removed the genetic information from a donor egg cell and replaced...
