Human Mast Cells (HMC-1 5C6) Enhance Interleukin-6 Production by Quiescent and Lipopolysaccharide-Stimulated Human Coronary Artery Endothelial Cells
Figure 3
Transmission and scanning electron microscopy. The ultrastructural assessment of HMC-1 5C6 cells demonstrates the presence of cytopslasmic granules; (a) shows HMC-1 5C6 clone exhibited numerous electron-dense granules (arrows) indicating maturity of the cells (magnification 14,000X); (b) shows a scanning electron micrograph of HMC-1 5C6 in a typical co-culture experiment demonstrating endothelial cell-mast cell interaction (magnification 2600X).
