Transplant Tissue Engineering

The Transplant Tissue Engineering (TransTissuE) is a collaboration project between the University of Skövde, VERIGRAFT and XVIVO, aiming to develop methods and strategies for optimization of the production process of personalized tissue-engineered vascular transplants.

These transplants are manufactured by the removal of the cellular content, decellularization (DC), from donor blood vessels while preserving the structural and functional molecular units of the remaining extracellular matrix (ECM). A recellularization (RC) procedure is then applied to repopulate the ECM with autologous cells and other components from blood samples from the recipient patient (Figure 1). This strategy allows the modulation of the immunological response system and limits implant rejection. However, knowledge about how this critical modulation is controlled is still lacking. By applying extensive data analysis on large-scale omics datasets, the project aims to implement  a modeling approach to reveal how the risk of implant rejection could be reduced.

The project will analyze comprehensive proteomics and transcriptomics datasets from the different stages during the DC and RC procedures of blood vessels (Figure 2). Advanced large-scale data mining will be applied to these complex omics datasets, including machine learning techniques to investigate the mechanisms related to the modified immunological response and reduction in transplant rejection. Furthermore, biomarkers will be identified and selected for development of decision support systems for quality control of the RC and DC processes.

The results of this project are anticipated to contribute to the development of personalized transplants and to improved treatments for patients with damaged blood vessels.
