For the angiopoietic axes genes, the mRNA transcript levels for SDF-1b and VEGF were undetectable in the cultures from IPF patients while for the mock infected primary cultures from healthy donors were quantifiable with ratio of the means 0.00 (p = 0.01 and p = 0.076 respectively). Here, CXCL12 is linked to idiopathic interstitial pneumonia.
