Abstract
Thermo-sensitive hydrogels which could encapsulate cells and provide a three dimensional (3D) microenvironment have great potential in building new cell culture models in vitro. In this study, a thermal responsive hydrogel based on PLGA-PEG-PLGA tri-block copolymers was developed as matrix for 3D ovarian cancer cell culturing. The gelation of PLGA-PEG-PLGA tri-block copolymer was concentration-dependent. SEM images showed the pores were suitable for the formation of 3D cell structures. Cell morphological results showed that large aggregates of ovarian cancer cells (HO8910) were formed after cultured for 10 days. Therefore, hydrogel based on PLGA-PEG-PLGA tri-block copolymers hold potential as in vitro cell culture matrix for ovarian cancer cells.
