PTP-BL deficiency in stromal, but not hematopoietic, cells phenocopies the reduced bleomycin-induced pulmonary fibrosis seen in whole-body PTP-BL–deficient mice. (A) Lung hydroxyproline levels and (B) stereology-quantified lung injury in saline- and bleomycin-instilled PTP-BL^−/− to wild-type (Wt) and Wt to PTP-BL^−/− mice. (C) Trichrome-stained sections from saline- and bleomycin-instilled PTP-BL^−/− to Wt and Wt to PTP-BL^−/− mice. Values are mean ± SEM. n = 5 mice per group. Bleo = bleomycin; ns = no significant difference.
