Research Abstract

For the first time, we succeeded in visualization of two distinct subtypes of retinal ganglion cell. For the purpose of elucidation of mechanisms for determination of retinal ganglion cell subtype and regular mosaic formation, we tried isolation of the subtype-specific genes using single-cell microarray method but failed. However, we succeeded in isolation of a gene which is commonly expressed in these two retinal ganglion cell subtypes. We revealed the electrophysiological property of the two subtypes. Furthermore, we found that these the two subtypes projected to the medial terminal nucleus via different pathways.
