Abstract
Current therapy for pancreatic cancer is multimodal, involving surgery and
chemotherapy. However, development of pancreatic cancer therapies requires a
thorough evaluation of drug efficacy in vitro before animal
testing and subsequent clinical trials. Compared to two-dimensional culture of
cell monolayer, three-dimensional (3-D) models more closely mimic native
tissues, since the tumor microenvironment established in 3-D models often plays
a significant role in cancer progression and cellular responses to the drugs.
Accumulating evidence has highlighted the benefits of 3-D in
vitro models of various cancers. In the present study, we have
developed a spheroid-based, 3-D culture of pancreatic cancer cell lines
MIAPaCa-2 and PANC-1 for pancreatic drug testing, using the acid phosphatase
assay. Drug efficacy testing showed that spheroids had much higher drug
resistance than monolayers. This model, which is characteristically reproducible
and easy and offers rapid handling, is the preferred choice for filling the gap
between monolayer cell cultures and in vivo models in the
process of drug development and testing for pancreatic cancer.
