Functioning brain tissue grown in 3-D structure

Researchers at the RIKEN Center for Developmental Biology in Japan have succeeded in inducing human embryonic stem cells to self-organize into a three-dimensional structure similar to the cerebellum, providing tantalizing clues in the quest to recreate neural structures in the laboratory.

A few cells could prevent bone marrow transplant infections

Bone marrow transplantation is a life-saving therapy for patients with blood cancers like leukemia or lymphoma. However, the depletion of the patient’s immune system prior to transplantation can put patients at risk of for an infection by a virus called cytomegalovirus (CMV) that can be life threatening in these immune-compromised individuals. Now, researchers have found that a very small subset of anti-viral immune cells, transplanted along with a donor’s blood stem cells, could be enough to fight and even prevent the disease caused by CMV.
