Spinner Flask Bioreactor in Tissue Engineering

Abstract

Spinner Flask Bioreactors are usually made up of glass or plastic vessel which have been widely used in Tissue Engineering from production of articular cartilage to production of osteoblast cells that help in bone regeneration. Cartilage grown in spinner flask bioreactors had more cells and less GAG than the other types of bioreactors in tissue engineering. In recent years, these bioreactors have also been used for the invitro cultivation of human tenocytes and MSCs. In this type of bioreactor, the cell/scaffold constructs are connected to vertical needles striking from pinnacle of the vessel and immersed inside the culture medium. The pinnacle or the top part of this bioreactor is used for gas exchange and medium oxygenation. Mixing of the medium is maintained with a stir bar at the lowest of the vessel or different blending mechanisms. Spinner Flask Bioreactors have grabbed increased attention in recent years due to its wide range of Tissue Engineering applications. In this review, we have tried to explore the different domains where these bioreactors have found enhanced applications.
