::Clone sheep Dolly

The researchers selected udder cells from a six year old Finn-Dorset and bread them for several weeks in the laboratory. The cells were differentiated, adult and somatic with Diploid cores. From the cell culture certain cells were selected and put on a sort of diet, withholding them of a growth factor. This way the cells entered a state of rest at the exactly when there genes were most susceptible to reprogramming. Subsequently, the researchers took ovules from a sheep of the Scottish Blackface race and removed the cores. Then they fused each coreless ovule with an udder cell by emitting small electric shocks. Due to this electrical fusion, that places a full set of genetic material in the ovule, it is activated. Normally this is done by the spermatozoon resulting in a 50-50 percent merging of the spermatozoon’s genetic material and the genetic material already present in the ovule. The result is 277 cells in total. These were implanted in the tied up fallopian tubes of several Scottish Blackfaces. Six days later they were removed. Out of the 247 recovered, 29 had evolved into blastocysts. These were then planted in the wombs of 13 ewes, only one birthed a healthy lamb. On the fifth of July 1996 the Scottish Blackface ewe gave birth to a Finn-Dorset lamb. The lamb, originating from an udder cell, was named Dolly after the famous round breasted country singer Dolly Parton.
