Hans
Spemann published the landmark results of his 1928 primitive nuclear transfer
experiment
involving salamander embryos in his 1938 book
"Embryonic Development and Induction." In
this book, Spemann claimed the next logical step for
research to be the "fantastical experiment," as
he called it, of cloning organisms by extracting the nucleus of a differentiated cell and inserting it into an enucleated fertilized egg. Also in
the book, Spemann proposed the exciting idea of cloning
from adult cell nuclei. However, Spemann was unable to
technically devise a way to attempt any such experiments
during his lifetime. No one succeeded in doing so until Robert Briggs and Thomas J. King cloned
tadpoles in 1952. Without knowing it, Briggs' and King's
method of cloning using the nuclear transfer method was
highly similar to Spemann's 1938 "fantastical
experiment" proposal. [ Home ] [ The Details ] [ Reactions ] [ Interactions ] [ About Site ] [ Bibliography ] |
