Our bodies are not 2-Dimensional. Our cells don’t grow on flat plates. Various technologies have been used over the years to culture cells in 3-D Conditions. Those 3-D conditions have now been applied to stem cells, creating “mini-organs”. Harvard explored combining stem cells and chip technology in early 2014 examining cardiovascular disease (Nature Published Article).
Kyoto University has furthered the 3-D culturing technology with a thermoresponsive gel. The microfluidic chip combined with the thermoresponsive gel creates a microenvironment for cells to grow in a 3-D with specific temperature and environment control.
This technology can help to grow increased functional cells resulting in more reliable data about cells, gene expression, drug screening, and various other applications.
