Comparison of Migration Disturbance Potency of Epigallocatechin Gallate (EGCG) Synthetic Analogs and EGCG PEGylated PLGA Nanoparticles in Rat Neurospheres

Epigallocatechin gallate (EGCG), the main catechin of green tea, is described to have potential health benefits in several fields like oncology, neurology or cardiology. Currently, it is also under pre-clinical investigation as a potential therapeutic or preventive treatment during pregnancy against...
