Figure 15. Rotating tissue culture vessels, which simulate some aspects of microgravity, allow human cells to grow and assemble into 3-dimensional tissues. This new class of culture vessel has enabled the growth of normal and cancerous human tissues outside the body and is a tool for gaining important information with applications in medicine and the biology. The figure shows a human cell grown in a rotating tissue culture vessel.
