bFGF Prevents Apoptotic Death and Partially Protects from Necrosis 24 h after Exposure to Apoptosis Inducers

Cell treatment*		Viability		DNA fragmentation
		%		%
TNF 2 ng/ml		0		86 ± 6.5
TNF + bFGF 2 ng/ml		58		0
UV light 0.06 J/cm2		0		78 ± 7.0
UV light + bFGF 2 ng/ml		50		0

^* U937 cells were pretreated 3 h with bFGF before exposure to TNF or UV light. 24 h later, viability was determined by trypan blue exclusion and DNA fragmentation was measured by release of ³H-labeled DNA fragments.
