Tg-induced intracellular calcium ion concentration changes in 3T3 cells. A: The fluorescent intensity in 3T3 cells was 25-30 in Ca2+-free and 2 mmol/L EGTA-containing medium after treatment with 4 μmol/L Tg; B: The fluorescent intensity rose to 50-55 in 3T3 cells after adding 2 mmol/L CaCl2; C: Similar intracellular free Ca2+ concentration dynamic changes in 3T3 cells and Tg-induced elevation of [Ca2+]i in 3T3 cells 120 min after treatment.
