Among these chains, only the laminin {\ensuremath{\alpha}} chain is capable of signaling via laminin receptors. Although laminin isoforms containing the {\ensuremath{\alpha}}5 chain were reported to be the first laminin produced during rat anterior pituitary gland development, the functions of these isoforms are unknown. We used immunohistochemical techniques to localize the laminin {\ensuremath{\alpha}}5 chain and its specific receptor, basal cell adhesion molecule (BCAM), in fetal and adult pituitary gland. Laminin {\ensuremath{\alpha}}5 chain immunoreactivity was observed in the basement membrane of the primordial adenohypophysis at embryonic days 12.5 to 19.5. Double immunostaining showed that BCAM was present and co-localized with the laminin {\ensuremath{\alpha}}5 chain in the tissue. Quantitative analysis showed that the laminin {\ensuremath{\alpha}}5 chain and BCAM were expressed in the anterior pituitary gland during postnatal development and in adulthood (postnatal day 60). In the adult gland, co-localization of the laminin {\ensuremath{\alpha}}5 chain and BCAM was observed, and BCAM was detected in both the folliculo-stellate cells and endothelial cells. These results suggest that laminin {\ensuremath{\alpha}}5 chain signaling via BCAM occurs in both the fetal adenohypophysis and adult anterior pituitary gland.}, author = {Morio Azuma, Morio Azuma and Takehiro Tsukada, Takehiro Tsukada and Takeshi Inagaki, Takeshi Inagaki and Fujianti Casmad, Fujianti and Depicha Jindatip, Depicha Jindatip and Alimuddin Tofrizal, Alimuddin and Rita Maliza, Rita Maliza and Khongorzul Batchuluun, Khongorzul Batchuluun and Rahimi Syaidah, Rahimi Syaidah and Nobuhiko Ohno, Nobuhiko Ohno and Ken Fujiwara, Ken Fujiwara and Motoshi Kikuchi, Motoshi Kikuchi and Takashi Yashiro, Yashiro} }
