Cytometric observations on hemopoietic kidney tissue in catfish (Ictalurus melas). 1978

C Garavini, and G Giulianini, and P Martelli, and L Villani

Peroxidase-positive and negative lymphoid hemoblasts present in Catfish kidney were measured, in order to verify whether large lymphoid hemoblasts give rise to the granulocytic leukocytes and small lymphoid hemoblasts give rise to the erythrocytes, thrombocytes and lymphocytes. The cytometric study indicates that granulocytic cells arise prevalently by large and intermediate sized hemoblasts, but also by small hemoblasts. The other cells arise prevalently by small and intermediated sized hemoblasts and by large ones as well. Two different types of hemoblasts were distinguished but not on the basis of their size.

UI MeSH Term Description Entries
D007668 Kidney Body organ that filters blood for the secretion of URINE and that regulates ion concentrations. Kidneys
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D010544 Peroxidases Ovoperoxidase
D005399 Fishes A group of cold-blooded, aquatic vertebrates having gills, fins, a cartilaginous or bony endoskeleton, and elongated bodies covered with scales.
D006098 Granulocytes Leukocytes with abundant granules in the cytoplasm. They are divided into three groups according to the staining properties of the granules: neutrophilic, eosinophilic, and basophilic. Mature granulocytes are the NEUTROPHILS; EOSINOPHILS; and BASOPHILS. Granulocyte
D006410 Hematopoiesis The development and formation of various types of BLOOD CELLS. Hematopoiesis can take place in the BONE MARROW (medullary) or outside the bone marrow (HEMATOPOIESIS, EXTRAMEDULLARY). Hematopoiesis, Medullary,Haematopoiesis,Medullary Hematopoiesis
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
