            Abstract: The aim of this paper is to raise awareness of the ArtiVasc 3D project and its findings. Vascularization is one
            of the most important and highly challenging issues in the development of soft  tissue. It is necessary to supply cells with
            nutrition within a multilayer tissue, for example in artificial skin.  Research on artificial skin is driven by an increasing
            demand for two main applications. Firstly, for the field  of regenerative medicine, the aim is to provide patients with
            implants or grafts to replace damaged soft  tissue after traumatic injuries or ablation surgery. Secondly, another aim is to
            substitute expensive and ethically  disputed pharmaceutical tests on animals by providing artificial vascularized test beds
            to simulate the  effect of pharmaceuticals into the blood through the skin. This paper provides a perspective on ArtiVasc
            3D, a major European Commission funded project that explored the development of a full thickness, vascularized artifi-
            cial skin. The paper provides an overview of the aims and objectives of the project and describes the work packages and
            partners involved. The most significant results of the project are summarized and a discussion of the overall success and
            remaining work is given. We also provide the journal papers resulting from the project.
