“…The chorioallantoic membrane (CAM) assay, used for more than half a century, has become a mainstay in the study of blood vessel development (Auerbach et al, 2003;Cruz et al, 2000;Cruz et al, 1997;DeFouw and DeFouw, 2000a;DeFouw and DeFouw, 2000b;Djonov et al, 2000a;Djonov et al, 2000b;McDonnell et al, 2005;Rizzo and DeFouw, 1996;Rizzo et al, 1995;Rizzo et al, 1993). The CAM assay has also proved useful for biological devices and in tissue engineering applications, particularly those concerning biocompatibility studies and angiogenic responses to tissue-engineered constructs (Borges et al, 2003a;Borges et al, 2003b;Nguyen et al, 1994;Ribatti et al, 2001;Rickert et al, 2003;Valdes et al, 2003;Valdes et al, 2002;Wong et al, 2003).…”
