title: CXCL14-like immunoreactivity in growth hormone-containing cells of urodele pituitaries.
abstract: Immunohistochemical techniques were employed to investigate the distribution of a chemokine, namely, CXCL14-like immunoreactivity in the axolotl (Ambystoma mexicanum) and Japanese black salamander (Hynobius nigrescens) pituitaries. CXCL14-immunoreactive cells concentrated at an area of the pars distalis adjacent to the pars intermedia. We found that these cells correspond to the cells immunoreactive to an antibody against rat growth hormone (GH). Immunoelectron microscopy indicated that the CXCL14-like substance and GH coexisted on the secretory granules in the axolotl pituitary. Western blot analysis of axolotl pituitary extracts revealed the anti-human CXCL14 antibody labeled an approximately 16.6-kDa band that was not labeled by the anti-GH antibody. The CXCL14-like substance in the pars distalis may participate in GH functions in these species.
