28899816-6	2017	We also prepare multi-shell nanoparticles in different layers with a calcium phosphate core and DNA/calcium phosphate shells conjugated with polyethyleneimine to act as non-viral vectors for delivery of plasmid DNA encoding BMP2 and TGF-beta3, respectively.	aziridine	141-158	bone morphogenetic protein 2	Homo sapiens	224-228	
22815074-1	2012	The goal of this study was to determine the effectiveness of using polyethyleneimine (PEI) and a polyethylene glycol (PEG) tether to bind human recombinant bone morphogenetic protein-2 (rhBMP-2) to hydroxyapatite (HAp) to enhance rhBMP-2 loading, alter its release properties, and enhance cellular interaction with the material.	aziridine	67-84	bone morphogenetic protein 2	Homo sapiens	156-184
