BIM Final Review 2
Lecture 3: Biomechanics and TE
| Question | Answer |
|---|---|
| Bone heals, cartilage doesn’t. Why? | Cartilage isn't vascular |
| water, collagen (types I and II), glycosaminoglycans (GAG) | Cartilage composition |
| Biomechanical forces can make cartilage | Important in development to differentiate stem cells Normal loading is important in maintaining cartilage Can enhance regeneration Can be used in vitro in a bioreactor to help engineer more native-like neocartilage |
| Biomechanical forces can break cartilage | Create osteoarthritis |
| Cartilage loading cycles per year | 1-2 million cycles |
| Tissue engineering paradigm | Cells, bioactive factors/signals, scaffolds |
| Recent work shows elements of paradigm can be | used in combination or alone |
| The self-assembling process is a method to | engineer cartilage that only requires cells Can use signals, but not needed. The process is scaffold-less |
| The self-assembling process | Isolation of chondrocytes, seeding cells into cylindrical agarose mold, self-assembly into engineered cartilage |
| Stem cells can also be chondro-induced and self-assembled to form | engineered cartilage Dermis isolated adult stem (DIAS) cells |
| Translating engineering advances to medicine (TEAM) Facility | 3D scanning, design software, 3D printers, analysis software, catheter manufacturing, laser cutting/engraving, printed circuit board manufacturing Wet lab equipment, synthetic biology design, innovation space |
| Technology transfer paradigm | Academic research, new technology, new company |
