  1. Values expressed as means (±SD) of 7 (E) - 30 (C) animals per group. All values were computed in ten random, non-coincident fields per mice. Fractional area of normal, collapsed, and hyperinflated alveoli. Lm, mean linear intercept. In the control (C) group, saline was instilled intratracheally. In the emphysema (E) groups, mice received porcine pancreatic elastase intratracheally. At day 21, all groups were randomized to receive saline and bone marrow (BM), adipose (AD), or lung (L)-derived mesenchymal stem cells (MSC, 1 × 105 cells) intravenously (IV) or intratracheally (IT). *Vs. C group (p < 0.05). #Vs. E-SAL group (p < 0.05). Vs. BM-MSC-IV group (p < 0.05). Vs. BM-MSC-IT group (p < 0.05).
