Uptake of pGFP NP into MDM, MDDC or epithelial cells (EC): unloaded CTC NP (white square), CTC pGFP NP (black shaded white square) and CTPPC pGFP NP (black dotted white square). Presented data are the mean ± standard error of the mean of three independent experiments. Differences were considered significant for * (p < 0.05).
