In many organisms the extracellular matrix (ECM) is involved in the migration of cells. This thesis investigates the role of the ECM in the Aiptasia-Symbiodinium symbiosis. Commercially available antibodies against mammalian collagen IV, laminin, and beta-integrin successfully label Aiptasia proteins in both symbiotic and aposymbiotic anemones. In an attempt to alter the ECM, anemones were incubated in ethyl-3,4- dihyroxybenzoate (EDHB) and beta-aminopropionitrile (BAPN). These anemones presented with distinct morphological differences, however, they did not show notable changes to the ECM as detected by immunofluorescence. EDHB does cause bleaching of symbiotic anemones, possibly by affecting the algal cell wall.
