Human Umbilical Cord-Mesenchymal Stem Cells Combined With Low Dosage Nintedanib Rather Than Using Alone Mitigates Pulmonary Fibrosis in Mice.

ABSTRACT: Pulmonary fibrosis (PF) is a lethal pathological change of fibrotic interstitial lung diseases (ILDs) with abundant fibroblasts proliferation after severely or continually alveolar epithelial cells (AECs) injury. Barely therapies are helpful for PF. Here we use bleomycin intratracheally injection to model PF with or without human umbilical cord-mesenchymal stem cells (hUC-MSCs) and/or nintedanib intervention. RNA-Seq followed with real-time PCR and western blot were used to find out the specific possible mechanisms of the effects of hUC-MSC and nintedanib on PF. Immunostaining, cell counting kit-8 (CCK-8), and 5-bromo-2'-deoxyuridine (BrdU) incorporation assay were used to detect the cell proliferation in vivo or in vitro separately. We found that hUC-MSCs alone had prophylactic, but not t
