AB  - Cell scaffolds are often used in cell transplantation as they provide a solid structural support to implanted cells and can be bioengineered to mimic the native extracellular matrix. Gadolinium fluoride nanoparticles (Gd-NPs) as a contrast agent for Magnetic Resonance Imaging (MRI) were incorporated into poly(lactide-co-glycolide)/chitosan scaffolds to obtain Imaging Labelled Cell Scaffolds (ILCSs), having the shape of hollow spherical/ellipsoidal particles (200–600 µm diameter and 50–80 µm shell thickness). While Gd-NPs incorporated into microparticles do not provide any contrast enhancement in T1-weighted (T1w) MR images, ILCSs can release Gd-NPs in a controlled manner, thus activating MRI contrast. ILCSs seeded with human mesenchymal stromal cells (hMSCs) were xenografted subcutaneously into either immunocompromised and immunocompetent mice without any immunosuppressant treatments, and the transplants were followed-up in vivo by MRI for 18 days. Immunocompromised mice showed a progressive activation of MRI contrast within the implants due to the release of Gd-NPs in the extracellular matrix. Instead, immunocompetent mice showed poor activation of MRI contrast due to the encapsulation of ILCSs within fibrotic capsules and to the scavenging of released Gd-NPs by phagocytic cells. In conclusion, the MRI follow-up of cell xenografts can report the host cell response to the xenograft. However, it does not strictly report on the viability of transplanted hMSCs. © 2019 by the authors.

AB  - Cell therapy is promising strategy that has attracted a lot of attention recently regarding regeneration of diverse tissues and treatment of various pathological conditions. Despite its great potential, several issues still need to be addressed. Among them administration route and dose, microenvironment conditions and host immune response are recognized as a major causes which lead to cells transplantation failure. In this work it is presented novel microstructural system based on biodegradable polymer poly(lactide-co-glycolide) (PLGA) and combination of biocompatible polyvinyl alcohol (PVA) and chitosan, as a scaffold for human mesenchymal stem cells (hMSCs) growth. The obtained microparticles with diameter 200-600 μm showed full biocompatibility with human hMSCs. Besides serving as a solid support, polymeric particles provided controlled release of contrast agent - gadolinium fluoride nanoparticles (Gd-NP) up to 5 weeks. The release of Gd-NP is enhanced by acidic conditions. Magnetic Resonance Imaging (MRI) of the samples embedded in 1% agar showed that contrast enhancement in T1-weighted (T1w) MR images is influenced by the amount of released Gd-NP. Based on these preliminary results, presented theranostic system could be considered for cells grafting.
