To determine the expression pattern of multiple subtypes of cadherin adhesion receptor in postnatal mouse neural retina.
The expression of N-cadherin, R-cadherin, cadherin-6, cadherin-8, and cadherin-11 in retinas at postnatal days 0 to 42 was analyzed by in situ hybridization of mRNA as well as by immunohistochemistry.
Each cadherin was expressed by different cell populations of the retina, and the following expression patterns were established by postnatal day 14: in the ganglion cell layer, all these molecules were expressed, but each occurred only in a subset of the cells. Likewise, in the inner nuclear layer, R-cadherin and cadherin-6 and -8 were expressed by a restricted population of amacrine cells, and cadherin-8 also by a subpopulation of bipolar cells. All horizontal cells expressed R-cadherin, and Muller cells expressed N-cadherin and cadherin-11. Proteins of R-cadherin and cadherin-6 were concentrated in neuropil layers.
The pattern of differential expression of the five cadherins supports the idea that these molecules may play a role in selective cell interactions within the heterogeneous cell pool of the neural retina.
