3-parent technology

A new piece came out yesterday on the Wellcome Trust Blog, strongly promoting approval of so-called “3-Parent IVF” or Mitochondrial Transfer technology by the UK Parliament. As I written in the past (here and here), my view is that this would be a mistake at this time. There is room for respectful disagreement on this issue between scientists, although I realize I’m up against some very prominent scientists including Drs. Peter Braude and Robin Lovell-Badge, whose past response to my open letter to the UK Parliament was …Read More

The following is a response to my Open Letter to the UK Parliament on mitochondrial transfer/3-parent technology from Drs. Peter Braude and Robin Lovell-Badge. Dear Professor Knoepfler, We read your open letter to the UK Parliament and the Science and Technology Committee with interest and concern. We are two scientists, like you, with particular interests in genetics, stem cell and developmental biology and preimplantation genetic diagnosis, who were appointed amongst others to form a Panel of independent advisors to the HFEA and the UK …Read More

It’s a particularly exciting time for the stem cell field. One of the most notable developments in the last year or so is the production and preliminary study of a totally new type of human embryonic stem cells (ESC) made by nuclear transfer instead of using leftover in vitro fertilization (IVF) embryos. This process of so-called therapeutic cloning has the power to produce patient specific ESCs called NT-ESCs that can in principle be used in the future for autologous transplants for a number of diseases …Read More

Dear UK Parliament and Science and Technology Committee, I am writing to you about your deliberations on “mitochondrial donation” (also known as 3-parent technology) intended for the purpose of preventing heritable mitochondrial disorders. I am concerned about the Department of Health’s recent draft regulations that would allow 3-parent experiments to go forward and the possibility that the UK Parliament may vote to allow it. This experimental technology has a noble goal, but in my opinion there are too many unanswered questions and risks that remain to allow …Read More
