ERBB2 and neoplasm: These HER2-targeted BCMs were not studied in vivo, but the tumour and normal tissue uptake of non-targeted BCMs composed of MePEG-b-PCL and [111In]In-DTPA-PEG-b-PCL copolymers has been studied after i.v. injection in mice with s.c. MDA-MB-231 tumour xenografts (Hoang et al. 2009).
