Abstract

Improper fluid shear stress (FSS) can cause serious damages to bone marrow mesenchymal stem cells (MSCs). Mechano-growth factor (MGF) E peptide pretreatment was proposed to protect MSCs against FSS damage in this study. MSCs were exposed to FSS for 30 min after they were pretreated with MGF E peptide for 24 h. Then, the effects of MGF E peptide on the viability, proliferation and cell apoptosis of MSCs were investigated. MGF E peptide pretreatment could recover the cellular metabolic activity of MSCs reduced by 72 dyne cm(-2) FSS and had a synergistic effect with FSS on the cellular metabolic viability of MSCs under 24 and 72 dyne cm(-2) FSS. These results suggested that MGF E peptide pretreatment could be an effective method for the protection of FSS damage in bone tissue engineering.
