Bioreactor

Bioreactor and its applications
ABSTRACT:
Bioreactor is an instrument which was made by NASA to study the effect of microgravity (low shear stress) over a cell and its stimulus. And to prove that there is life in space. Bioreactor will produce microgravity and provide artificial life supporting system. The cultivation of cells in horizontally rotating vessels under low shear stress has become extremely popular in recent years, and its non-rotating counterpart, low-gravity cell culture in space flight is also gaining popularity. In microgravity cell is growing due to low shear stress. Bioreactor is aided in cell culture technologies that simulate microgravity and their use in tissue engineering. NASA has developed these technologies to provide a ground-based model of microgravity for cell and biotechnology research. Researchers have subsequently found that the unique properties of microgravity offer many advantages in tissue engineering, especially in promoting 3-dimensional growth and assembly of cells into functional tissues
INTRODUCTION:
The National Aeronautics and Space Administration, in concert with the biomedical community, has initiated work that offers significant advances in cell culturing technology on Earth that enables further unique research progress which is called BIOREACTOR. More than 100 projects are under progress based on bioreactor and their results are applied in public interest in the fields of health care, tissue engineering, drug testing, transplantation of tissues and organs etc...
What is a bioreactor?
NASA scientists have developed a rotating culture vessel called a bioreactor that simulates a microgravity environment. They are meeting the challenge with a unique new technology, the rotating wall vessel bioreactor. It spins a fluid medium filled with cells to neutralize most of gravity’s effects and encourage cells to grow in a natural manner. Bioreactor is shown in the (fig1.1).
