Figure 1. P2X7−/− stromas show altered expression of collagen and related proteins. Real Time PCR results±SEM of at least three independent experiments were calculated using the ΔΔCt method and normalized to 18S rRNA. All sample results are presented relative to the median WT sample, normalized to 1. Negative controls were performed without reverse transcriptase. * p<0.03, Student’s t-test.
