SUMMARY OF THE PROPORTION OF CELLS EGFP-POSITIVE IN AIRWAY AND ALVEOLAR TISSUES AFTER INTRATRACHEAL ADMINISTRATION OF LENTIVIRAL SUPERNATANT

		EGFP Analysis of Airway Cells		EGFP Analysis of All Alveolar Cells
Animal	Vector	Cells Counted*	Number of GFP+CC10+	Cells Counted†	Number of GFP+proSPC+	% GFP+ Cells
IT1-8	CC10	422	10			2.4
IT4-11	CC10	496	18			3.6
IT2-2	SPC			638	16	2.5

Definition of abbreviations: CC10, Clara cell 10-kD protein; EGFP, enhanced green fluorescent protein; GFP, green fluorescent protein; SPC, surfactant protein C.

^*Exclusively airway cells were counted for this analysis.

^†All cells within in the alveolar region were counted for this analysis, and thus includes AECI, AECII, as well as vascular and hematopoietic cells.
