Dr. Arsenault is investigating various aspects of bone structure, growth and dynamics with the use of different ultrastructural imaging techniques. We are specifically interested in the nature of extracellular mineral formation and the manner in which the mineral becomes organized within collagen fibrils. In addition to bone, we have studied a variety of other calcifying tissues (growth plate, tendon, tooth enamel and dentin). Also, the micro-architecture of the bone vascular system is being studied by several different structural methods. A wide range of electron microscopic techniques are used: elemental analysis, cryogenic specimen preparation, image analysis, freeze fracture, immunolocalization.
