Caenorhabditis elegans is a powerful tool to study cellular migration and morphogenesis during organ development. During pharynx development, the dorsal gland cell, g1p, is born in the anterior aspect of the pharyngeal primordium and undergoes a form of morphogenesis called retrograde extension. egl-15, the single Fibroblast Growth Factor Receptor (FGFR) in C. elegans and ina-1, one of two α-integrin receptors, are both required for the proper extension or migration of g1p cell. Mutations in either egl-15 or ina-1 show similar gland cell over-migration defects where the gland cell body migrates past the terminal bulb and is located in proximity of the intestine. The kinase domain of EGL-15 was found to be required for migration and transgenic rescue strategies were used to determine the tissue of EGL-15 function. RNA interference was used to determine if egl-15 and ina-1 are functioning in the same pathway to regulate gland cell migration. / February 2015
