Cultivation, characterization and modulation of rat thymic non-lymphoid cells in vitro.
Thymic fragments of young adult rats were cultivated in vitro using an explant technique. Two weeks later, non-lymphoid cells were characterized by enzyme-cytochemistry and immuno-cytochemistry. Based on cytomorphological criteria and cell-specific markers approximately 95% of cells were classified into 3 main types: epithelial cells, macrophages and fibroblasts. The effect of dexamethasone and amphotericin B, known modulators of cell growth in culture was also studied. Quantitative analysis showed that amphotericin B inhibited proliferation of macrophages and epithelial cells, while dexamethasone suppressed proliferation of fibroblasts and promoted growth of epithelial cells.
