These cells, such as circulating tumor cells, or CTC is known, can provide critical information for examining and diagnosing cancer metastasis, determining patient prognosis, and monitoring the effectiveness of therapies.
Nanopillar chip more than 10 times the amount of cells captured captured by the currently used flat structure, said lead study author Dr. Shutao Wang, a postdoctoral researcher at both the Crump Institute for Molecular Imaging at the David Geffen School of Medicine at UCLA and the California NanoSystems Institute at UCLA.. In a study published this month in the journal Angewandte Chemie, the UCLA team developed a 1 – by-2 – centimeter silicon chip that covered with densely packed nanopillars and looks like a shag carpet. Cell cell capture performance, researchers incubated nanopillar chip in a culture medium with breast cancer cells. As a control, they performed a parallel experiment with a cell-capture method that uses a chip with a flat surface. Both structures were coated with anti-EpCAM protein, the protein, the easier to detect and to detect tumor cells coated.In 1993 adopted the which WMA a statement on female genital mutilation these practices convicted as a form of oppression of female in 2005 further strengthened their opposition pushing national Medical Chamber with education programs for doctors to create the.
