Debate Reignites Over the Contributions of ‘Bad Luck’ Mutations to Cancer

(Science) – How much of cancer is due to random “bad luck”? More than 2 years ago, a pair of researchers brought that question to prominence when they tried to sort out environmental versus inherited causes of cancer. They examined … Read More

New Stem Cell Method Produces Millions of Human Brain and Muscle Cells in Days

(Medical Xpress) – Wellcome Trust Sanger Institute scientists and their collaborators at the University of Cambridge have created a new technique that simplifies the production of human brain and muscle cells – allowing millions of functional cells to be generated … Read More

Early Treatment with Stem Cells Can Safely Help Recovery in Stroke Patients, Study Shows

(News-Medical) – A multicenter trial looking at whether a single dose of millions of adult, bone-marrow-derived stem cells can aid stroke recovery indicates it’s safe and well-tolerated by patients but may not significantly improve their recovery within the first three … Read More

From Skin to Brain: Stem Cells without Genetic Modification

(PhysOrg) – A discovery, several years in the making, by a University at Buffalo research team has proven that adult skin cells can be converted into neural crest cells (a type of stem cell) without any genetic modification, and that … Read More

3 Women Blinded by Unproven Stem Cell Treatments

(NPR) – Scientists have long hoped that stem cells might have the power to treat diseases. But it’s always been clear that they could be dangerous too, especially if they’re not used carefully. Now a pair of papers published Wednesday … Read More

Lab-Grown Mini-Organs Help Model Disease, Test New Drugs

(Science) – To the naked eye, the little globs of cells are undifferentiated masses, smaller than sesame seeds. Put them under a microscope, though, and these lab-grown miniature organs show striking complexity: the tiny tubules of a kidney, the delicate … Read More

Waiting to Reprogram Your Cells? Don’t Hold Your Breath

(Scientific American) – They can also give rise, however, to potentially dangerous mutations, possibly including ones that lead to cancerous tumors. Thus, iPS cells are a double-edged sword—their great promise is tempered by risk. Another problem is the high cost … Read More
