Abstract
Hydrogels have been widely studied, especially as injectable materials for applications as biomaterials. These hydrogels may possess thermosensitive features near body temperature (LCST - Lower Critical Solution Temperature - around 37ºC), in addition to rapid gelation, which allows it use as carrier drugs, cells or cell growth factors as injections. The current challenge is to make these materials biodegradables and suitable the mechanical properties for their use. The aim of this study will be to synthesize hydrogels of poly(N-iropropylacrylamide) (PNIPAAm) from a new class of macromer consisting of 2-hydroxyethyl methacylate (HEMA), poly(L-co-D,L lactic acid) and trimethylene carbonate (PLDLA-co-TMC) in order to synthesized material with inherent characteristics such as biodegradability and mechanical properties compatible to required applications in the field of tissue engineering. In addition, another aim for the hydrogel will assess your role as substrate in the differentiation of bone marrow-derived mesenchymal stem cells of rabbits in cardiomyocytes, aiming future application in cardiac tissue engineering.
