Growing vertebrae in the cervical (neck) region of a fetus. At this stage the tissue is mostly cartilage (blue) that is being replaced by the laying down of new bone tissue (pink strips) at the mid-point of each vertebral body. Note formation of early bone marrow spaces at the waist of each vertebra. This type of skeletal development is called endochondral ossification. Magnification x70 when printed at 10cm height.
