Research Description

Morphological Evaluation of Bone, Cartilage, and Connective Tissues

The laboratory has the expertise to evaluate various components of the musculoskeletal system either at the adult or embryonic stage of development, and to relate morphological adaptations to normal functional aspects of the involved tissues. The techniques presently available for such studies include, transmission and scanning electron microscopy, processing of calcified tissues, morphometric measurements at the tissue and cellular level of interest, immunocytochemistry, histochemistry, and various light microscopy related techniques. A major interest is to collect morphometric measurements at the cell or tissue level, so that quantitative evaluation of morphological changes can be determined on a statistical basis.
