Abstract
Individual surface(hydrophilic/hydrophobic) were prepared and mammalian cells were cultured on the hydrophilic region. For drug test, cancer and normal cells were treated with Taxol, as an example. Our system was compared with MTT assay. CHO cells were resistant to Taxol up to 100 nM in both Methods. However, A549 cells was sensitive at 100 nM Taxol in the 2 day-treatment. Cervical carcinoma cell, HeLa, was very sensitive to Taxol. In our system, the cells were not shown from above 20 nM Taxol treatment. Our system was competitive to MTT assay in animal cells for drug test.
