The locating of this research revealed that the best percentage of cells had been early polychromatophilic rubricytes in the erythroid series and myelocytes Rabbit Polyclonal to CNNM2 in the myeloid series. Rubriblasts had been big cells with huge central circular nuclei with nucleoli. The nucleus-cytoplasm percentage was high. The cytoplasm was basophilic and vacuolated deeply. Pro-rubricytes resembled rubriblasts, but their chromatin was even more dense, nucleoli were indistinct and their cytoplasm very basophilic deeply. Basophilic rubricytes had been smaller sized than prorubricytes having a circular nucleus including clumped chromatin (Figs. 1 and ?and2).2). Early poly-chromatophilic rubricytes were round cells with a grey (basophilic to slightly eosinophilic) cytoplasm. The CP-724714 kinase activity assay nucleus of these cells was small in relation to the cytoplasm and had clumped chromatin (Figs. 1 and ?and2).2). Late poly-chromatophilic rubricytes were approximately oval in shape with a nucleus round to slightly oval containing irregularly clumped chromatin (Fig. 2).

LPR: late polychromatophilic rubricyte; PR: early polychromatic rubricyte; Br: basophilic rubricyte; Er: erythrocyte; PT: prothrombocyte; T: thrombocyte. Myeloblasts were large and round with a narrow rim of blue cytoplasm. Their nucleus was round with a reticular chromatin and prominent nucleoli. Promyelocytes were large round cells with light blue cytoplasm and eccentric round nucleus. Their cytoplasm contained dark magenta granules. Myelocytes were smaller than promyelocytes. They had a spherical shape with an eccentric oval nucleus. Their cytoplasm contained secondary granules (particular granules) that could become categorized as the heterophil (Fig. 1), eosinophil (Fig. 3) or basophilic (Fig. 3) series. Heterophilic, basophilic and eosinophilic myelocytes contained not even half the definitive amount of adult granules. Eosinophilic myelocytes lacked the magenta granules (Fig. 3).

Er: erythrocyte; Em: eosinophilic myelocyte; Bm: basophilic myelocyte; PT: prothrombocyte. Metamyelocytes had been smaller sized than their precursor cells. Their nucleus was somewhat indented or bean form and their cytoplasm got over fifty percent the definitive amount of particular granules (Fig. 1). Music group cells resembled the adult granulocyte but lacked the lobed nucleus. Thromboblasts CP-724714 kinase activity assay weren’t seen in pheasant bone tissue marrow, but, prothrombocytes and thrombocytes had been observed in low percentages (Figs. 1, ?,22 and ?and3).3). Promonocytes had been huge cells with very clear blue cytoplasm including granules and circular nuclei having a reticular nuclear chromatin. The prolymphocyte and lymphoblast weren’t seen in pheasant bone marrow samples. Plasma cells had been to oval cells having a circular circular, placed nucleus eccentrically. A pale part of cytoplasm was noticed near one part from the nucleus. Osteoclasts had been large multinucleated huge amoeboid cells. Their cytoplasm contains eosinophilic granules in various sizes and shapes, and was also vacuolated. Their nuclei were round to oval with finely granular chromatin and prominent nucleoli (Fig.4). There was no significant difference in any of the cellular composition between male and female. Open in a separate window Fig. 4 Photomicrograph of osteoclast (o) in bone marrow of male pheasant. Giemsa staining. Discussion A unique feature of avian species is that erythropoiesis.
