DONOR DEMOGRAPHICS OF NONASTHMATIC PHAEC CULTURES USED FOR EPITHELIAL GENE EXPRESSION ARRAY

Donor	Sex	Age (yr)	Sample Type*	Cause of Death
N1	M	20	Donor lung	Head trauma
N2	F	20	Donor lung	Head trauma
N3	M	21	NHBEs (Lonza, Basel, Switzerland)
N4	F	23	Bronchial brushing
N5	M	47	Donor lung	Head trauma

Definition of abbreviations: F, female; M, male; N, nonasthmatic; NHBEs, normal human bronchial epithelial cells; PHAEC, primary human airway epithelial cell.

^*Airway epithelial cells were obtained from the upper airways of human lungs deemed unsuitable for transplantation, from bronchial brushing or commercially available NHBEs. All donors lacked doctor-diagnosed asthma.
