The paper from a team led by Qiang Sun is entitled, “Cloning of Macaque Monkeys by Somatic Cell Nuclear Transfer.” The highlight bullet points from the paper are the following: “•Somatic cell nuclear transfer (SCNT) using fetal fibroblasts yielded two live monkeys •Epigenetic modulators promoted development and pregnancy rate of SCNT embryos •SCNT …Read More

Below are the 2016 stem cell predictions I made last year and their status now color-coded near year’s end. Green is right, orange is mixed bag, and red is flat out wrong. Overall, I did better than most past years with only having entirely blown it on four. Stay tuned later this week for my 2017 predictions, which looks to be a dramatic year in the field of stem cells and regenerative medicine. The Score Card on 2016 Predictions Another stem cell biotech acquisition by pharma …Read More
