Development of
Bioreactors for Tissue Engineering
Tissue Engineering often involves
the culture of cells on polymer scaffolds for extended periods of time outside
of the body. A major challenge involved
in these cultures is the recreation of the multitude of stimuli normally seen
by cells in vivo. Depending on the
specific tissue of interest, this may involve static and dynamic mechanical
loads as well as diffusive and convective transport of nutrients to growing
tissues. This project involves the
design and fabrication of “bioreactors” for the controlled application of
mechanical loads and solute flows to cell-seeded polymers.
In prior work we have demonstrated
that fluid flow as well as static and dynamic compression regulates the
metabolism of cartilage cells. The
current project involves the development of cyclic shear bioreactor with
controlled nutrient flow for the cultivation of tissue engineered
cartilage. Such devices will be designed
for sterility and the ability to function in a physiologic environment.
This project is well suited for a
team of 2-3 students with a strong background in mechanical design, familiarity
with CAD software, programming in LabView, and
machining. Tasks for this project include design, fabrication, and validation
of a working tissue culture bioreactor.
