Modification of Human Umbilical Cord Blood Stem Cells Using Polyethylenimine Combined with Modified TAT Peptide to Enhance BMP-2 Production

Viability of hUCB-MSC treated with PEI, PEI25, or mTAT/PEI complexes of gWiz-BMP2. The MTT assays were performed 24, 48, and 72 hours after transfection, and the cell viability obtained was expressed as a percentage of nontreated cells (taken as 100% viability).
