33231238-3	2020	The polymeric micelle is composed of a CD44-targeting shell and a FAP-alpha-cleavable polyethylene glycol (PEG) coating.	Polyethylene Glycols	86-105	fibroblast activation protein alpha	Homo sapiens	66-75	
33231238-4	2020	When FAP-alpha is encountered on the surface of CAFs in the tumor microenvironment, the PEG layer is released, hyaluronic acid is recovered on the surface of nanoparticles, and the nanoparticles effectively inhibit the growth of tumor cells and CAFs through CD44-mediated endocytosis.	Polyethylene Glycols	88-91	fibroblast activation protein alpha	Homo sapiens	5-14
