Lysophosphatidic acid (LPA) is a lipid growth factor that exerts diverse biological effects through its cognate receptors ($LPA_1-LPA_6$). $LPA_1$, which is predominantly expressed in the brain, plays a pivotal role in brain development. However, the role of $LPA_1$ in neuronal migration has not yet been fully elucidated. Here, we delivered $LPA_1$ to mouse cerebral cortex using in utero electroporation. We demonstrated that neuronal migration in the cerebral cortex was not affected by the overexpression of $LPA_1$. Moreover, these results can be applied to the identification of the localization of $LPA_1$. The subcellular localization of $LPA_1$ was endogenously present in the perinuclear area, and overexpressed $LPA_1$ was located in the plasma membrane. Furthermore, $LPA_1$ in developing mouse cerebral cortex was mainly expressed in the ventricular zone and the cortical plate. In summary, the overexpression of $LPA_1$ did not affect neuronal migration, and the protein expression of $LPA_1$ was mainly located in the ventricular zone and cortical plate within the developing mouse cerebral cortex. These studies have provided information on the role of $LPA_1$ in brain development and on the technical advantages of in utero electroporation.
