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.
Anita Shukla, Assistant Professor of Engineering, has been awarded a grant from the Office of Naval Research. Professor Shukla and her group will work on the development of an advanced antimicrobial field dressing for use in military applications. Military infections exist commonly in a variety of wounds and significantly complicate wound treatment. The cause of these infections can vary from different types of planktonic and biofilm bacteria to fungi, and wounds may contain combinations of several of these microbes.
