Résumé | Polymeric scaffolds containing biomimics offer exciting therapies with broad potential impact for cellular therapies and thereby potentially improve success rates. Here we report the designing and fabrication of a hybrid scaffold that can prevent a foreign body reaction and maintain cell viability. A biodegradable acrylic based cross-linkable polycaprolactone based polymer was developed and using a multihead electrospinning station to fabricate hybrid scaffolds. This consists of cell growth factor mimics and factors to prevent a foreign body reaction. Transplantation studies were performed subcutaneously and in epididymal fat pad of immuno-competent Balb/c mice and immuno-suppressed B6 Rag1 mice and we demonstrated extensive neo-vascularization and maintenance of islet cell viability in subcutaneously implanted neonatal porcine islet cells for up to 20 weeks of post-transplant. This novel approach for cell transplantation can improve the revascularization and allow the integration of bioactive molecules such as cell adhesion molecules, growth factors, etc. |
