Transfection of a galectin-7 expression vector increases TUNEL-positive nuclei in SCC13 cells

	Hours posttransfection
	18	36	54
TUNEL	5.7	11.1	3.3
Floating cells	1.7	2.2	5.7

SCC13 keratinocytes grown on slides and floating cytocentrifuged cells were processed for immunolabeling of galectin-7 and TUNEL reactions. TUNEL indicates the ratio of (TUNEL-positive/total) cells in pBK-CMV-1A12-transfected cells to (TUNEL-positive/total) cells in pBK-CMV-transfected cultures. Floating cells indicates the ratio of floating cells in pBK-CMV-1A12- to pBK-CMV-transfected cultures. Results are from mean cell numbers (+/− 10%) obtained in two independent experiments.
