Third instar larvae expressing MapmodulinEY01282 under the control of Scer\GAL4Pxn.PS have a decreased number of sessile hemocytes. The number of hemocytes in circulation is similar to wild type. The dorsal sessile hemocyte department is slightly disrupted. Sessile hemocytes do not accumulate along the dorsal vessel or spread through the cuticle. The lymph gland is enlarged. Hemocyte shape is normal.
