要旨

The neural cell recognition molecule F11 is a member of the immunoglobulin superfamily. During development it is expressed on axons in neuropils, and it is implicated in neurite outgrowth and in fasciculation. F11 is a multifunctional protein that interacts with L1/Ng-CAM, Nr-CAM, tenascin-C, tenascin-R (restrictin) and receptor protein tyrosine phosphatase beta. Here we show that F11 is not only expressed on neurons, but also on Müller cells and Schwann cells in vitro. Using two independent cell culture techniques, stratospheroids which represent an in vitro regeneration system of the chicken retina, and purified Schwann cells from chicken sciatic nerve, we show that Müller cells and Schwann cells express F11. On semithin cryosections of stratospheroids we were able to colocalize F11 with the Müller cell markers vimentin and 3A7. Expression of F11 by purified Schwann cells in demonstrated histologically and by immunoblot analysis. These in vitro data suggest the involvement of F11 in glia-neuron or glia-neurite interactions.
