Characterization of human amniotic mesenchymal stromal cells (hAMSCs). Phenotype of unprimed (a) and paclitaxel (PTX)-primed (b) hAMSCs. The percentage of positive cells is indicated in each plot. Cell morphology is shown in panel c, magnification × 4. The images on the left show unprimed hAMSC (top) or hAMSC after the 24-hour treatment with 2,000 ng/ml of PTX (bottom). The images on the right show unprimed hAMSC (top) or hAMSC at the time at which conditioned media and lysates were collected and tested for their anti-proliferative activity against CFPAC-1 (bottom, 48 hrs)
