Figure 4From: Stimulation of TM3 Leydig cell proliferation via GABAA receptors: A new role for testicular GABAImmmunocytochemical evidence for the presence of GAD and VGAT in TM3 cells. A cytoplasmatic staining pattern for GAD (glutamate decarboxylase) and VGAT (vesicular GABA transporter) was observed in TM3 cells (A, B). Controls included using non-immune serum (C) and omission of primary antiserum. Bars: 15 μm.Back to article page
