HMOX1 and infection: Therefore, in this study, we transduced bone marrow MSCs (BMMSCs) with an adenoviral vector carrying the heme oxygenase gene (Ad/HO-1) and infused them into rats after SBTx in order to investigate whether HO-1 gene infection improves the MSC survival rate in vivo and whether Ad/HO-1-transduced MSCs (Ad/HO-1/MSCs) play an enhanced effect in improving outcomes of SBTx in rats.
