3D bioprinted cartilage

3D bioprinted cartilage

  • A team from Indian Institute of Technology (IIT) Delhi has been successful in 3D bioprinting of cartilage using a bioink.
  • The bioink has high concentration of bone-marrow derived cartilage stem cells, silk proteins and a few factors.
  • The chemical composition of the bioink supports cell growth and long-term survival of the cells.
  • The cartilage developed in the lab has remained physically stable for up to six weeks.
  • While the cartilage found in the knee is an articular cartilage that is typically sponge-like and has a huge load-bearing capacity, the ones produced in the lab so far are of a different kind — transient cartilage.
  • Unlike articular cartilage, transient cartilage becomes bone cells and, therefore, brittle within a short time.
  • As a result, the engineered cartilage loses its capacity to bear huge load that is typically encountered in the knee.
