In 1958, Gurdon, then at the University of Oxford, successfully cloned a frog using intact nuclei from the somatic cells of a Xenopus tadpole. [ 21 ] [ 22 ] This work was an important extension of work of Briggs and King in 1952 on transplanting nuclei from embryonic blastula cells [ 23 ] and the successful induction of polyploidy in the ...
In 1958, John Gurdon, then at Oxford University, explained that he had successfully cloned a frog. He did this by using intact nuclei from somatic cells from a Xenopus tadpole. [40] This was an important extension of work of Briggs and King in 1952 on transplanting nuclei from embryonic blastula cells.
The first vertebrate ever to be cloned was an African clawed frog in 1962, [35] an experiment for which Sir John Gurdon was awarded the Nobel Prize in Physiology or Medicine in 2012 "for the discovery that mature cells can be reprogrammed to become pluripotent".
In particular, the research of Sir John Gurdon in 1958 entailed the cloning of Xenopus laevis utilizing the principles of SCNT. [5] In short, the experiment consisted of inducing a female specimen to ovulate, at which point her eggs were harvested.
In 1958, John Gurdon, then at Oxford University, explained that he had successfully cloned a frog. He did this by using intact nuclei from somatic cells from a Xenopus tadpole. [38] This was an important extension of work of Briggs and King in 1952 on transplanting nuclei from embryonic blastula cells.
The employment of adult somatic cells in lieu of embryonic stem cells for cloning emerged from the foundational work of John Gurdon, who cloned African clawed frogs in 1958 with this approach. The successful cloning of Dolly led to widespread advancements within stem cell research, including the discovery of induced pluripotent stem cells .
1958 – John Gurdon used nuclear transplantation to clone an African Clawed Frog; first cloning of a vertebrate using a nucleus from a fully differentiated adult cell. 1958 – Matthew Stanley Meselson and Franklin W. Stahl proved that DNA replication is semiconservative in the Meselson-Stahl experiment
John Gurdon used nuclear transplantation to clone an African clawed frog; first cloning of a vertebrate using a nucleus from a fully differentiated adult cell. 1972.
