WNT7B Stimulates New Bone (image) Washington University School of Medicine Caption As seen through a microscope, the leg bone of a normal mouse (left) makes considerably less new bone than a mouse that produces high levels of a signaling protein, WNT7B, that stimulates new bone growth (shown in pink on the right). The protein could become a target for new drugs to treat osteoporosis and other conditions related to bone loss.
