Fluorescence microscope micrographs showing transverse sections of the 5th lumbar vertebral body. Note the newly formed bone among three labels in the anterior and posterior cortical bone and the red fluorescence mostly on the surface of the few trabecular remnants of Groups 3 and 4. Group 2: control, normal diet; Group 3: calcium-deprived diet for 4 weeks; Group 4: calcium-deprived diet, plus concomitant administration of PTH (1-34) 40 μg/kg/day, for 4 weeks. Scale bar: 500 μm.
