Dr. Gordana Vunjak-Novakovic and her colleagues have managed to create living bone from stem cells. First, they made a CT scan to create a 3-D image of each pig’s jaw. From cow bone, they sculpted a “scaffold” — a three-dimensional copy of the pig bone. Read more at New York Times.
A new phase 1 clinical trial evaluated the differences between pre-operative prone and supine MRI exams in 12 women undergoing lumpectomy for breast cancer. Researchers demonstrated that considerable deformity of the breast and tumor position occurs when patients are imaged in the prone position. Read more at Medical Xpress.
A new technique repairs large bone defects in the head and face by using lab-grown living bone, tailored to the patient. This is the first time researchers have grown living bone grown to precisely replicate the original anatomical structure, using autologous stem cells derived from a small sample of the recipient's fat.

Observations of how T-cell receptors reposition during an immune response could help scientists better understand how to regulate the immune system’s activity to treat autoimmune diseases, infections or even cancer. Read more at Salk News.
In its third year, eMerge Americas brings together technology experts, enthusiasts, and investors from all over the world. Held this year in Miami, it included NIBIB-funded scientists demonstrating their neural-enabled prosthetic arm that is designed to give sensation back to an amputee.

An international team of researchers funded in part by the National Institute of Biomedical Imaging and Bioengineering (NIBIB), part of the National Institutes of Health, has discovered distinct roles for two types of vessels within the bone marrow, an understanding that could help improve stem cell transplants and create better interventions for diseases like leukemia. One type of vessel preserves a pool of stem cells, while the other type promotes stem cell differentiation into new blood cells and the migration of the new blood cells out of the bone marrow.
Physicians have long used magnetic resonance imaging (MRI) to detect cancer, but results of a new study describe the potential use of restriction spectrum imaging (RSI) as an imaging biomarker that enhances the ability of MRI to differentiate aggressive prostate cancer from low-grade or benign tumors and guide treatment and biopsy.
