Special Issue Information

Dear Colleagues,

The initial reaction that takes place when a biomaterial is implanted into the human body is a non-specific inflammatory response that can range from good biocompatibility with a mild inflammatory reaction through a rejection reaction to complete integration of the material in the optimal case. In this context, a rapid supply with blood vessels (vascularization) is considered one of the key factors in regeneration and is therefore crucial for a good integration of the material. Specifically, there is a need for the development of biocompatible and functional biomaterials that might improve the process of angiogenesis. In order to evaluate biomaterials’ biocompatibility and functionality (i.e., angiogenesis), the development of in vitro tissue engineered cell culture systems is essential since a better understanding of healing mechanisms can be generally assisted by in vitro studies. Tissue engineered human in vitro equivalents might significantly contribute to the understanding and improvement in developing new beneficial materials and might allow for the transfer into the clinic.

Scope: This Special Issue will focus on original research papers and comprehensive reviews, dealing with cutting-edge new developed biomaterials to improve angiogenesis, as well as establishing and investigating cell culture models and in vitro tissue equivalents to analyse/improve the process of angiogenesis and evaluate certain materials.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Bioengineering is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Type I collagen, prevalent in the extracellular matrix, is biocompatible and crucial for tissue engineering and wound healing, including angiogenesis and vascular maturation/stabilization as required processes of newly formed tissue constructs or regeneration. Sometimes, improper vascularization causes unexpected outcomes. Vascularization failure may be caused by extracellular matrix collagen and non-collagen components heterogeneously. This study compares the angiogenic potential of collagen type I-based scaffolds and collagen type I/glycosaminoglycans scaffolds by using the chick embryo chorioallantoic membrane (CAM) model and IKOSA digital image analysis. Two clinically used biomaterials, Xenoderm (containing type I collagen derived from decellularized porcine extracellular matrix) and a dual-layer collagen sponge (DLC, with a biphasic composition of type I collagen combined with glycosaminoglycans) were tested for their ability to induce new vascular network formation. The AI-based IKOSA app enhanced the research by calculating from stereomicroscopic images angiogenic parameters such as total vascular area, branching sites, vessel length, and vascular thickness. The study confirmed that Xenoderm caused a fast angiogenic response and substantial vascular growth, but was unable to mature the vascular network. DLC scaffold, in turn, produced a slower angiogenic response, but a more steady and organic vascular maturation and stabilization. This research can improve collagen-based knowledge by better assessing angiogenesis processes. DLC may be preferable to Xenoderm or other materials for functional neovascularization, according to the findings. Full article
