Reduction of CD90 expression does not affect mesenchymal stromal cell (MSC) morphology and proliferation rate. a Representative phase contrast microscopy images of MSCs derived from dental pulp. All MSCs displayed a spindle-like morphology exhibiting relatively thin processes extending from the cell bodies. The photographs shown here are representative of all samples analysed (n = 7). b Proliferation curves of non-transduced MSCs, short hairpin (sh)RNA control MSCs, shRNA CD90 MSCs, and CD90-negative MSCs. Data shown represent the mean ± SD of two independent experiments performed in triplicate with dental pulp MSCs from two tissue donors; *p < 0.05
