Meeting Abstract
Often overlooked in many cell biology laboratory and cell culture courses; suspension cells represent an important aspect of cell biology and cell culture. Most primary cell cultures and cell lines are adherent cells which grow in monolayers on surfaces. However, other cells such as hematopoietic cells, certain tumor cells, and cells of the immune system are suspension cells which are anchorage-independent meaning they grow and divide in solution. THP-1 cells are a commercially available, spontaneously immortalized monocyte-like cell line derived from the peripheral blood of a patient with acute monocytic leukemia. These cells are an excellent model for suspension cell culture, and studies of the immune system. Researchers have used THP-1 cells to study the host response to implantable devices and biomaterials in vitro. Tissue contacting surfaces of implantable materials initiate a host inflammatory response characterized by many events, one of which includes macrophage attachment to the surface, which ultimately leads to degradation and failure of the material. Using the THP-1 adhesion assay embedded in this CURE, students can participate in the scientific process by testing substances which may prevent the host inflammatory response to implantable devices and biomaterials.
