Six undergraduate biomedical engineers travelled to the annual meeting of the national Biomedical Engineering Society in San Antonio October 22nd-25th. At the conference, attendees presented research done at Brown to a national audience of academic professionals.
By sorting human fat tissue cells by their expression of a certain gene, Brown University scientists were able to retrieve a high yield of cells that showed an especially strong propensity to make bone tissue. With more refinement, the method could improve the ability of surgeons to speed bone healing.
Scientists have hailed recent demonstrations of chemical technologies for making animal tissues see-through, but a new study is the first to evaluate three such technologies side-by-side for use with engineered 3-D tissue cultures.
A microscopic obstacle course of carefully spaced pillars enabes researchers to observe cancer cells directly as they break away from a tumor mass and move more rapidly across the microchip. The device could be useful for testing cancer drugs and further research on the mechanics of metastatis.
