Effect of hADSC and hBMSC on total collagen levels measured by hydroxyproline assay. Lung collagen deposition was increased by repeated OVA challenge, but this was suppressed by both MSC treatments. OVA ovalbumin, PBS phosphate buffer saline, hADSC human adipose-derived stem cell, hBMSC human bone marrow mesenchymal stem cell. *P < 0.05 compared to control, #P < 0.05, ##P < 0.01 compared to the OVA + PBS group.
