Effect of TGF-β pretreatment on the lag time of [Ca²⁺]_c and [Ca²⁺]_m responses (measured at half height of the signal) and on the propagation time (coupling time) of the cytosolic signal to the mitochondria

Stimulus	Lag Time of Response [Ca2+]c, s		Lag Time of Response [Ca2+]m, s		Coupling Time, s
	Naive	TGF-β-Pretreated	Naive	TGF-β-Pretreated	Naive	TGF-β-Pretreated
All 2 nM	11.5±1.2	64.5±3.1	14.9±1	79.2±5.7	5.33±0.5	12.9±2.6
All 100 nM	1.9±0.2	30.4±1.5	3.5±0.3	33.26±1.6	1.6±0.1	5.2±0.3

Values represent means ± SE responses from 36–166 cells.
