Fig. 7From: Synergistic co-administration of docetaxel and curcumin to chemoresistant cancer cells using PEGylated and RIPL peptide-conjugated nanostructured lipid carriersTumor spheroid growth inhibition. A Optical images of MCF7/ADR tumor spheroids after treatment with different formulations for 5 days. Scale bar represents 100 μm. B Changes in the volume of tumor spheroids. DTX- or CUR-equivalent concentration was 500 ng/mL or 1500 ng/mL. Data represent the relative ratio (%) as a percentage of volume of the day n to that of day 0. Data represent the mean ± SD (n = 3)Back to article page
