among higher vertebrates , a similar situation is found in the bovine and chicken nervous systems , in which the arachnoid cells of the meninges contain desmosomes and ifs of both the cytokeratin ( apparently with restricted epitope accessibilities in the chicken ) and the vimentin type , whereas the perineurial cells of many nerves contain cytokeratin ifs , often together with vimentin , but no desmosomes .
