Collagen content and collagen cross-linkage in lungs of wild-type and periostin-null mice. (A) Collagen contents (percentage of tissue dry weight) and pyridinoline (PYD) contents (mol/mol of collagen) for 19-week-old wild-type (+/+; n=3) and periostin-null (−/−; n=2 for collagen content and n=3 for PYD contents) mice. (B) Same type of data for 35- to 36-week-old wild-type (+/+; n=4) and periostin-null (−/−; n=6) mice. Statistical significance of differences: **p<0.01 as indicated by the brackets (p=0.0095 in each analysis of B).
