Model: IRM maintains ECs and germline within signaling distance enabling EC extension formation. In IRM knockdown, attachment of ECs and germline is hindered, increasing the distance between these two cell types. As a result, the soluble ligand Spi does not activate Egfr signaling in ECs to the same extent and less membrane protrusions form and encapsulate the germline.
