CD172a⁺ cells were isolated by high-speed cell sorting (>98% purity) from PBMC cultures stimulated with rESAT-6:CFP-10 for 6d and evaluated by transmission electron microscopy. A cell with morphology representative of the majority of the CD172a⁺ cells within the culture is depicted. Bar in lower margin indicates scale. The higher magnification inset is a multi-vesicular body.
