pubmed:abstractText
The haematopoietic tissue in the supraneural organ of the freshwater river lamprey (Lampetra fluviatilis L. Gray) was studied in sexually immature animals. Besides erythro- and granulopoietic elements, macrophages, reticular cells, fibroblasts and glycogen-rich fat cells were seen. Developing granulocytes of the lamprey contain one type of azurophil granules originating from small cytoplasmic (Golgi) vesicles. The lamprey's azurophil granulocytes seem to be homologous with those of fishes. However, the granulocytes of fishes, studied thus far, show granules with only one type of inclusion, whereas in lamprey the granulocyte inclusions are variable in size and shape. Thus, lamprey granulocytes are, in this respect, reminiscent of similar cells of higher vertebrates. The PAS and alkaline phosphatase reactions, common markers of vertebrate neutrophil leucocytes, are very weak in the haematopoietic tissue granulocytes of the lamprey, and intense in the blood cells of the same animal. Lamprey granulocytes, similarly to the granulocytes of Chondrostei and Elasmobranchiata, do not stain with peroxidase, naphthol-AS-D-chloroacetate esterase and sudan black B. The haematopoietic tissue contains a relatively high number of degenerated granulocytes.
