Fig. 2. TEM analysis of the coalesced gonad. (A,B) Stage 14 male wild type gonad, transverse section. Two germ cells are highlighted in yellow, two SGPs highlighted in pink and purple. (A) SGPs ensheath germ cells with thin cellular extensions. Note the unusual morphology of the purple SGP as it extends processes to ensheath the neighboring germ cell. (B) Higher magnification of region indicated in A. Two SGPs overlap each other to completely surround a germ cell.
