| 摘要 |
Cell lines have been prepared from growth suppressor gene deficient animals. The cells include immortalized precursor cells and differentiated cells such as osteoclast precursors, osteoblast precursors, megakaryocytes, osteoclasts, osteoblasts, pancreatic alpha -cells, pancreatic beta -cells, pancreatic delta -cells, adipocytes, macrophages, chondrocytes and hepatocytes. The cells are useful for constructing cDNA and protein libraries, screening agonists and antagonists of compounds and factors that affect metabolic pathways of specific cells and generating cell-specific antibodies.
