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.

Israeli doctors use 3D printing to rebuild injured Syrian man’s face

Now 3D printing implants is a complicated business as it is, but the jaw is particularly difficult to reproduce. After all, it’s completely filled moving parts that need to work perfectly – humans can get by with a limping leg, but they need to eat and drink. Dr Yoav Leiser and his team therefore relied on CT scanning and 3D printing to produce a 3D printed titanium ‘Patient Specific Implant’ (or PSI), and the procedure proved to be very successful. Surgery was performed by Leiser and Professor Adi Rachmiel, director of Rambam’s Department of Oral and Maxillofacial Surgery.

Miniature Spinal Cords Grown In The Lab

Scientists from the Dresden University of Technology have made a giant stride in the field of regenerative medicine, having successfully grown spinal cord-like tissue in the lab from embryonic stem cells. Although mouse cells were used, the study raises the possibility that one day, with further development, this technique could be used to help patients with spinal cord injuries.
