Printable tumors help scientists fight cancer
3-d printing of tumors:
Using a mixture of cervical cancer cells and a hydrogel substance that resembles an ointment balm, Sun can print out a tumor model that can be used for studying their growth and response to treatment. This living model will give cancer researchers a better look at how tumors behave and a more accurate measure of how they respond to treatment.
“This is the first time to report that one can build a 3D in vitro tumor model through 3D Printing technology,” said Sun, the director of Drexel’s research center at the Shanghai Advanced Research Institute. “This may lead to a new paradigm for cancer research and for individual cancer therapies. We have developed a technological platform and would like to work with biologists and pathologists to encourage them to use the developed platform for 3D biology and disease studies.”
While researchers have been able to make cell models and tissues using rapid prototyping methods for some time, Sun’s lab, is the first to produce a living 3D tumor model through additive manufacturing –also known as 3D printing. In a study published in the journal Biofabrication in April, Sun reports a procedure his team developed for growing research-grade models of cervical cancer tumors.
