This video describes the technique of seeding mesenchymal stem cells (MSCs) onto a biodegradable poly(lactic acid) (PLA) scaffold. The prepared scaffolds can be implanted into the surgical resection cavity of the brain from where they may migrate towards tumor foci. Further, these cells can be engineered to express therapeutic proteins to stimulate apoptosis in cancer cells.
Protocol
1. Cell Culture and Scaffold Preparation NOTE: Scaffolds should be prepared 48 h prior to implantation in mice. The following volumes are provided on a per-scaffold basis. Multiply quantities as needed for additional scaffolds. Cut poly(lactic acid) (PLA) scaffolds into resection cavity-sized (approximately 2 mm x 2 mm) pieces. Scaffolds can be cut by hand using scissors or using a hole punch for repeatability. Sterilize by immersing in 7…
