<i>Gpat2</i> was expressed in mouse primary spermatocytes.

<p>A) Adult mouse testis sections were hybridized in situ with a <i>Gpat2</i> specific antisense probe (left panels) and the corresponding sense probe (right panels). Magnification: 100× (first row) and 600× (second row). A strong signal was detected in primary spermatocytes (black arrow). B) GPAT2 protein was detected in adult rat testis by immunofluorescence in the presence (left panel) or absence (right panel) of a specific GPAT2 antibody (green signal). The GPAT2 signal was detected in spermatocytes as well as in spermatides. Nuclei were stained with propidium iodide (red signal). Magnification: 400×. The highest GPAT2 expression was detected in the spermatocytes. Bar: 50 µm.
