Scientists at the University of California have found a potential new use for human embryonic stem cells: helping cancer patients recover the cognitive function lost when their brains are treated with radiation.
People with tumors in their head or neck often undergo radiation therapy after the cancer is surgically removed. Radiation helps kill malignant cells left behind. But it also can debilitate the hippocampus, the brain region responsible for learning, memory and processing of spatial information.
The researchers wondered whether embryonic stem cells could pick up the slack.
So they radiated the heads of 18 rats. Two days later, six of those
Former Hollywood producer Dominick Dunne died at the age of 83 after a long battle with bladder cancer. In past year he traveled to the Dominican Republic and Germany for stem cell treatments.
In the past year, Dunne had traveled to Germany and the Dominican Republic for experimental stem cell treatments to fight his cancer. He wrote that he and actress Farrah Fawcett were in the same clinic in Bavaria but didn’t see each other. Fawcett, a 1970s sex symbol and TV star of “Charlie’s Angels,” died in June at age 62.

Destroying abnormal stem cells could be a way to kill off bowel cancer in its very earliest stages, say UK experts.
Immature cells line the gut and normally replace and repair the tissue but malfunctions can lead to cancer.
Scientists believe detecting and obliterating these rogue cancer stem cells as soon as they appear could be a potent new anti-cancer strategy.
A UK National Stem Cell Network conference heard the same method might also work for other cancers.
Professor Malcolm Alison, of Barts and The London School of Medicine, has been looking at how bowel cancers grow
What are the biological processes that stem cells go through? What are the industrial processes we need to manufacturing? What do we know about cancer stem cells? How do iPS cells fit into the picture vs. embryonic stem cells? In this episode we investigate how the science and research of stem cells is being translated into industrial cell processes to create FDA approvable, and commercializable products. Differentiation, proliferation, migration, retro-differentiation, trans-differentiation, transformation into cancer cells, the role of tumors‘ micro environments and epigenetics and all reviewed here by the field’s foremost experts.
Stem-cell science is a fast-moving field. Just three years since a Japanese researcher first reprogrammed ordinary skin cells into stem cells without the use of embryos, scientists at a Massachusetts biotech company have repeated the feat, only this time with a new method that creates the first stem cells safe enough for human use. The achievement brings the potentially lifesaving technology one step closer to real treatments for disease.
Dr. Robert Lanza, chief scientific officer at Advanced Cell Technology (ACT), reported today in the journal Cell that his team has created stem cells using human skin cells and four proteins.
