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 ] Copyright 1998 by team 24355 and Kayotic Development. |
