Images of MC3T3-E1 pre-osteoblastic cells grown on chitosan membranes prepared from different chitin sources. A) Is an image of cells after 48 h grown on crab shell derived chitosan with 87% degree of deacetylation. B) Is an image of cells after 48 h grown on shrimp shell derived chitosan with 87% degree of deacetylation. Images were taken in an inverted microscope.
