Animals were treated with freshly isolated CB-CD34+ cells (0.5 x 10⁶ cells/pup) or CB-CD34+ cells expanded in basic medium or DEX medium (1-2 x 10⁶ cells/pup). Sham controls received equal volume PBS.
Values represent mean ± SD of (n) animals per group.
V(lu): lung volume; A_A(ae/lu): areal fraction of air-exchanging parenchyma; V(ae): volume of air-exchanging parenchyma.
*: P < 0.05; **: P < 0.01 versus PBS-treated sham controls.
(Student-t test).
