Doctors transplant windpipe with stem cells

The Big Issue is a magazine sold by homeless people throughout the UK on registered street pitches. Given the termination of our Big Issue pitches (see blog of 11 November “Letter of complaint to the chair of The Big Issue Foundation Charity”), we are pretty much unable to keep our account in the local internet cafĂ© (£3 for seven hours) going and are now restricted to the 3-hour maximum computer use per day at Idea Store Whitechapel library that our local council imposed on each of our membership cards on 1 February. I have had to adapt my blogs accordingly: the emphasis now is on the product of my research into the field of human embryonic stem (hES) cell research and therapeutic cloning, also known as somatic cell nuclear transfer (SCNT) – conferences, news, reports, discoveries and applications, major research institutions throughout world, joint international efforts, bloggers, etc – so that as soon as I have a laptop I am in a position to build within two weeks a website for our campaign in support of hES cell research and SCNT.

Claudia Castillo received trachea grown from her own cellsClaudia Castillo received trachea grown from her own cells

British newspapers report this morning that surgeons replaced the damaged windpipe of Claudia Castillo, a 30-year-old mother of two, with one created from bone marrow stem cells grown in a laboratory at Bristol University – Declan’s petition to the UN on therapeutic cloning has had 11 signings from Bristol University, and would have a lot more if the vast majority of emails I send to scientists and academics on his behalf were not going to spam boxes, or to cyberspace (see previous blog; on the subject: yesterday, after I posted the blog, I sent 163 emails to the United States, received two out-of office autoreplies, and not unsurprisingly no one signed – to date the petition has been signed by 583 scientists and academics, including 24 Nobel Laureates).

Britain’s top stem cell expert, Professor Stephen Minger of King’s College London (an early signatory of Declan’s petition) told the Evening Standard that the cutting-edge collaboration, involving doctors from Spain, the UK and Italy, was hugely important for future disease treatments. As the first scientist in the UK to grow human embryonic stem cells, he said: “This is a lovely example of how basic stem cell biology continues to yield new, exciting and clinically important treatments. I commend this international research team for such a co-ordinated and successful treatment approach.”

Professor Colin Blakemore of Oxford University, a former chief executive of the UK Medical Research Council (and another signatory of Declan’s petition), has a piece in today’s Times titled “An event that might really deserve to be called a breakthrough”. He writes that advances such as this trachea transplant “are the kind of encouragement that we need to have hope that stem cells and tissue engineering will eventually deliver the promised revolution in medical treatment”. Commenting on hES cell research, he writes: “At the much earliest steps on the ladder to treatment, researchers are now trying to grow entire organs – hearts, kidneys, pancreases – from embryonic stem cells, in test tube conditions. The capacity of embryonic stem cells to turn into virtually any other kind of cell obviously gives them the most potential for organ and tissue replacement. But there is much to learn about how to grow and control them and prevent them being rejected, before they are likely to be widely used.”

In the United States, the Wisconsin State Journal reports today that last week, President-elect Barack Obama’s transition team named a prominent University Wisconsin-Madison researcher - Alta Charo, a bioethicist and law professor who studies issues surrounding embryonic and other stem-cell research – to a panel reviewing federal health policy, including funding hES cell research. Obama has pledged to lift federal restrictions on the research. USA Today comments that Obama “could reignite an emotional national debate over the promise and the perils of medical research using cells taken from human embryos”. It adds: “The United States Conference of Catholic Bishops is warning that Obama will alienate millions, and abortion opponents are bracing for a fight.”

Yesterday I had the time to google the Sanford Consortium for Regenerative Medicine, an alliance of four San Diego research powerhouses: University of California, San Diego, The Burnham Institute, The Salk Institute and The Scripps Research Institute. The consortium renamed itself in September, after announcing a $30 million donation from South Dakota philanthropist T Denny Sanford. Sanford’s funding has been combined with a $43 million grant from the California Institute for Regenerative Medicine to build a four-story facility on North Torrey Pines Mesa for research in regenerative medicine. The new research center is expected to be open by 2010, with groundbreaking set to begin this January. The Consortium coordinated a one-day forum on 7 November at the Salk Institute which attracted several hundred biomedical researchers (Bruce Bigelow reported on the event on Xconomy and Science Network says that videos of the event will be available on its website soon).
