Proliferation, Adhesion, and Morphology of Bone‐Derived Stromal Cells on Xenogenic Collagen Matrices: An In Vitro Study

All three membranes resulted in a reduction in viability and increased cell stress of adherent cells compared to the control. A reduced viability was detected, in particular, in cells growing around NovoMatrix®. Morphologically, the cells showed signs of stress. This reaction indicates that the membranes may release substances that could impair the healing process in vivo, especially in the case of fast degradation.
