- 요약Cell-based therapeutics offer several advantages over traditional small molecules or protein-based therapies such as: ability to cross biological barriers, longer therapeutic index, and minimal toxicities. With many chemotherapies being toxic, there has been growing interest in specific drug delivery to the tumor site to mitigate off target side effects. Cell-based drug delivery has emerged as an approach to combat these toxicities and deliver drugs specifically at the tumor. Certain cells, such as stem cells, have demonstrated innate homing properties to the tumor site and thus appending chemotherapies onto cells can enhance specific drug delivery. However, many of these approaches require challenging formulations of nanoparticles, re-engineering of the technology depending on the cell type, or insufficient loading onto cell surfaces. To combat these challenges, we have developed a stable, broadly applicable cell surface modification capable of delivering drugs or other biomolecules. Herein, we demonstrate an efficient cell-based delivery system for the delivery of farnesylated Chemically Self-Assembled Nanorings (f-CSANs). These f-CSANs have the capability to be attached with chemotherapies as demonstrated in prior work. We utilize Mesenchymal Stem Cells (MSCs) due to their allogenic cell sourcing and innate tumor homing properties, as our cell delivery vehicle. We demonstrate MSCs can be modified with f-CSANs with a high loading capacity and that this modification is stable under physiologically relevant shear stresses. The f-CSANs are also shown to transfer from MSCs to target EGFR positive cancer cells, as observed in prior work, in a receptor dependent manner. In preparation for future biodistribution studies, we synthesized a new chemical dimerizer to functionalize the CSANs with a radiolabel or fluorophore. Our in vivo work demonstrates enhanced delivery of f-CSANs when tethered to the MSC cell surface over f-CSANs given alone. Importantly, the f-CSANs were also shown to be internalized by the tumor cells as observed with our in cellulo work. Preliminary data also demonstrates enrichment of MSCs in the tumor when f-CSANs are tethered on the cell surface, compared to MSCs given alone. This approach demonstrates a broadly applicable method for cell-based delivery of f-CSANs that is stable and efficient from in cellulo work to in vivo studies.
