Ca2+ responses of HPB.ALL subclones to TR agonists. CD45+ HPB.45.1 cells (□) or CD45-deficient HBP.45.0 cells (▨) were loaded with Indo-1 and stimulated with either 50 nmol/L thrombin or 120 μmol/L TFRIFD, and intracellular [Ca2+] was measured using a spectrofluorimeter. Values represent the mean ± SD of triplicate determinations.
