Gábor Vajta, MD, PhD, DSc (born 25 August 1952) is an Australian-Hungarian embryologist, Professorial Research Fellow at the Central Queensland University and Honorary Professor of the Beijing Institute of Genomics. After an early career in human pathology he turned to embryology in 1989 and since then has developed several patents relating to embryology, most notably the method of Handmade Cloning (HMC). HMC is a radical technical modification of Somatic cell nuclear transfer of the original mammalian nuclear transfer technology established by Willadsen and applied for somatic cells by Wilmut and Campbell.
Vajta’s achievements in embryology, either personal or by supervised students, include the establishment of a new incubation method for embryo production (Submarine Incubation System, SIS), establishment of a new vitrification method (Open Pulled Straw, OPS), establishment of a new method for culturing embryos (Well of Wells, WOW) however he is most recognised for the development of Handmade Cloning (HMC).
Handmade cloning (HMC) is a simplified form of Somatic cell nuclear transfer. The technique does not require micromanipulators only a simple stereomicroscope and an inexpensive fusion machine. All work is done by hand, with simple handheld tools (blade and micropipette).The first cloned animals in Africa and Scandinavia were both produced by HMC. Transgenic pigs as models for various human diseases were produced with putative genes responsible for Parkinson's and Alzheimer's disease, Psoriasis, Arteriosclerosis and Diabetes mellitus. The technology promises a new possibility for automation of the somatic cell nuclear transfer procedure. The birth of the first transgenic piglets containing the Alzheimer gene (29 October 2006) was rewarded as the Most important Scientific Achievement in Denmark in 2007.
