| Abstract | Fish pituitary plays a central role in the control of growth, development, reproduction and adaptation to the environment. Several types of hormone–secreting adenohypophyseal cells have been characterised and localised in diverse teleost species. The results suggest a similar distribution pattern among the species investigated. However, most studies deal with a single hormone or hormone family. Thus, we studied adjacent sections of the pituitary of Oreochromis niloticus, the tilapia, by conventional staining and immunohistochemistry with specific antisera directed against growth hormone (GH), prolactin (PRL), somatolactin (SL), thyrotropin (β–TSH), follicle–stimulating hormone (β–FSH), luteinising hormone (β–LH), adrenocorticotropic hormone (ACTH) and melanocyte–stimulating hormone (α–MSH). The pituitary was characterised by a close interdigitating neighbourhood of neurohypophysis (PN) and adenohypophysis. PRL–immunoreactive and ACTH–immunoreactive cells were detected in the rostral pars distalis. GH–immunoreactive cells were present in the proximal pars distalis (PPD). A small region of the PPD contained β–TSH–immunoreactive cells, and β–LH–immunoreactive cells covered approximately the remaining parts. Centrally, β–FSH–immunoreactive cells were detected in the vicinity of the GH–containing cells. Some of these cells also displayed β–LH immunoreactivity. The pars intermedia was characterised by branches of the PN surrounded by SL–containing and α–MSH–immunoreactive cells.The ACTH and α–MSH antisera were observed to cross-react with the respective antigens. This cross–reactivity was abolished by pre–absorption. We present a complete map of the distinct localisation sites for the classical pituitary hormones, thereby providing a solid basis for future research on teleost pituitary. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
