Mechanism involved in the response of granulated vesicles in the mouse pinealocyte to acute cold exposure

Summary Rudimentary cilia have been observed in muscle cells lining the tube feet of Ophioderma brevispinum (Ophiuroidea) and in muscle cells of the body wall and parapodial glands of Owenia fusiformis (Polychaeta). A diplosomal basal body is associated with each cilium. Striated rootlets are absent. This is the first report on rudimentary cilia in muscle cells of an echinoderm and an annelid.Supported by NSF grant #GB-42211 to R.M. Rieger.
