Abstract

In tissue engineering approach, the scaffold plays a key role for a suitable outcome of cell-scaffold interactions and for the success of tissue healing and regeneration. As a consequence, the characterization of scaffold properties and the in vivo evaluation of tissue responses and effects result to be essential in the development of suitable implantable device. Among the in vivo methods, the chick embryo chorioallantoic membrane (CAM) assay represents a rather simple and cost-effective procedure to study the biocompatibility responses of graft materials. CAM is indeed characterized by low experiment costs, simplicity, relative speed in obtaining the expected results, limited ethical concern, no need of high-level technical skill, and the absence of a mature immune system, resulting in an inexpensive, simple, and practical method to evaluate and characterize tissue-engineered constructs. The results till now obtained suggest that CAM assay can be used as a pre-screening assay, before in vivo animal studies, to determine whether the scaffold is liable to cause an adverse reaction and to evaluate its future enhancement of existing materials for tissue engineering. A review of the more recent results related to the use of CAM for in vivo biomaterial property evaluation is herein reported.
