Osteoblasts Protecting Cancer Cells (video) Princeton University Share Print E-Mail Loading video... Caption Yibin Kang of Princeton University has developed an antibody that fights bone metastasis by undermining cancer's defense strategy and allowing chemotherapy to work. This 3-D fluorescent image shows cancer's defense strategy: osteoblasts (red) surround the cancer cells (green) in bone, cradling and protecting them from chemotherapy. The nuclei of normal bone and blood cells are shown in blue. Kang's antibody inhibits the osteoblasts, thereby allowing chemotherapy to work against the cancer cells.
