Ligand (BAFF, APRIL) and receptor (BAFF-R, TACI, BCMA) mRNA levels in vCTB cells and MCs from term placentas assessed by real-time PCR

mRNA	vCTB/calibrator	MC/calibrator	vCTB/MC
Ligand
BAFF	0.2:1*	19:1*	1:95
APRIL	0.2:1*	53:1*	1:260
Exclusive BAFF receptor
BAFF-R	4.0:1*	12:1*	1:3
Shared receptors
TACI	0.5:1†	11:1†	1:22
BCMA	5.0:1†	12:1†	1:2

Values for vCTB cell mRNAs from three different placentas were averaged as were values for preparations of MCs taken from the same three placentas. The averaged values were used to establish ratios of levels of vCTB cells and MCs to the specific calibrator cell lines as well as the ratio of vCTB/MC.
