scaffold showed better results than the hyaluronic acid gelatin composite
scaffold, with signs of central necrosis in the HA gelatin composite scaffolds.
The polyurethane scaffold showed good porosity, excellent pore interconnectivity,
good cell distribution and cell survival, as well as an extensive content of
proteoglycans and collagen type II. The polyurethane scaffold seems to be a
promising biomaterial for a mesenchymal stem cell-based tissue engineering
approach for meniscal repair. The new score could be applied as a new standard
for in vitro scaffold testing.
