FIG. 1.

Specificity and time scale of the EECs of PBMCs from healthy volunteers. Different numbers of PBMCs were incubated with 1 ng of smooth LPS per ml, and changes in EECs determined by the LAL test are expressed. ○, 2 × 10⁶ PBMCs from 15 healthy volunteers; ⧫, 2 × 10⁵ PBMCs from 10 healthy volunteers; •, 2 × 10⁴ PBMCs from 7 healthy volunteers; ▿, 2 × 10⁶ cells of the pancreatic cancer cell line SW1116 (n = 3), ▴, 2 × 10⁶ cells of the colorectal cancer cell line HT29 (n = 3); ◊, 2 × 10⁶ cells of the hepatoblastoma cell line HepG2 (n = 3).
