Several kinds of PLGA-based biodegradable thermosentive polymers have been synthesized. The reversible sol-gel transition were characterized by viscosity measurement and revealed that LCST of these polymers were in the range of 15-25°C. Drug release behavior in the polymer gels has been conducted in vitro with Paclitaxel as a model compound. In the case of loading paclitaxel, addition of a hydrophobic component (lipiodol®) in the system seemed to get a better release profile. This study also shows intra-tumor injection of hydrogel-lipiodol mixture is very promising for the treatment of liver cancer. Besides, the potential for these thermosensitive polymers to be applied as embolization agent has been carried out in vivo in a rabbit model.
