The journalist, his brother, and the man who helped 20 million cancer patients
In 2011, journalist Chris Kimball noticed he was losing weight, along with other odd symptoms. The 35-year-old father of two young children found out he had an unusual and aggressive form of non-Hodgkins lymphoma, a cancer of the lymphatic system. And it was severe. It had spread to multiple lymph node sites, other organs and his bone marrow.
Within a week, Kimball had started treatment. He would need an intensive, brutal regime of chemotherapy followed by a bone marrow transplant to rebuild his immune system from scratch using donor stem cells from his brother.
Kimball’s road to recovery involved pain, fear, uncertainty, and several weeks in an isolation ward to protect him from infections.
“I don’t think you can under-estimate how full-on that process is,” he says.
“When you spike a fever and you have no immune system, it’s scary. It is the worst moment of your life and you’re completely isolated, waiting for that moment when you can start having some protection.”
Gruelling as Kimball’s treatment was, it would have been even tougher without a glycoprotein called granulocyte-colony stimulating factor (G-CSF). G-CSF stimulates the bone marrow to produce stem cells, white blood cells and other blood cells, and releases them into the bloodstream.
Colony stimulating factors—there are four different types—were discovered in the early 1980s by the pioneering Australian stem cell scientist Professor Donald (‘Don’) Metcalf, who pursued cancer research at Walter and Eliza Hall Institute (WEHI) in Melbourne. The Foundation’s Metcalf Prize for Stem Cell Research is named in his honour.

How a scientist says he made a gene-edited baby—and what health worries may ensue
George Seidel, Professor of Biomedical Sciences, Colorado State University, writing for The Conversation
On 28 November 2018, He Jiankui claimed to a packed conference room at the Second International Summit on Human Genome Editing in Hong Kong to have edited the genomes of two twin girls, Lulu and Nana, who were born in China.
Scientists at Southern University of Science and Technology in Guangdong, China, condemned He’s research asserting he “has seriously violated academic ethics and codes of conduct,” and philosophers and bioethicists were quick to dive into the morass of editing human genomes. So I’m not going to cover that territory. What I want to address is what we learned: how He made these babies.
I am theoretically a retired professor in the Department of Biomedical Sciences at Colorado State University. For more than 50 years, I have researched numerous aspects of assisted reproductive technology including cloning and making genetic changes to mammalian embryos, so I am interested in most any research concerning “designer babies” and the health problems they may suffer.
