Analysis of cells isolated from bone cultured on collagen gels and polystyrene culture dishes
Bone is a complex tissue which contains three types of differentiated cells viz., osteoblasts, osteoclasts and osteocytes. In mature bone, these cells are identified both by their location within the tissue and their morphological characteristics. In fetal tissue, one also finds many progenitor cells, fibroblasts and some cartilage cells. Each of these cell types has distinct functions which are reflected in their morphology, metabolic properties and response to hormones. Studies were also undertaken to evaluate the class of problems associated with electron microprobe analysis of the extracellular fluid space in bone. It was determined that differences in elemental composition in a small volume between cells and mineral cannot be quantitatively corrected for fluorescence, atomic number or absorption effects of the mineral. A study of the use of free-flow dialysis in the study of metal binding to protein demonstrates the anomalous behavior of mercury in this experimental approach and emphasizes the importance of a thorough examination of the control situation before protein to metal binding is examined.
