Research published this week describes a promising start to using stem cell therapy for multiple sclerosis. In a small Phase I trial, patients who had stem cells directly injected into their brain appeared to tolerate it well and experienced no serious adverse effects. The treatment may have also stopped or slowed the progression of their…
Now the stem cells are just showing off. An international team of researchers say they’ve developed a lab-grown mass of tissue that mimicked a brain and was able to spontaneously produce two symmetrical optic cups, eye-like structures sensitive to light. But don’t worry — these rudimentary organoids are not conscious.
