“…The intraembryonic site of hematopoiesis in bony fishes has perplexed developmental biologists, because at an analogous developmental stage, all other vertebrate species that have been examined form blood on the extraembryonic yolk sac (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13). In 1885, Wenckebach (12) hypothesized that the IM was formed by the convergent migration of two bilateral populations of hematopoietic progenitors; nevertheless, careful studies in the 20th century have failed to define the developmental origin of the IM (2)(3)(4)(5)(6)(7)(8)(9)(10)(11).…”

Vertebrate hematopoietic stem cells are derived from ventral mesoderm, which is postulated to migrate to both extra-and intraembryonic positions during gastrula and neurula stages. Extraembryonic migration has previously been documented, but the origin and migration of intraembryonic hematopoietic cells have not been visualized. The zebrafish and most other teleosts do not form yolk sac blood islands during early embryogenesis, but instead hematopoiesis occurs solely in a dorsal location known as the intermediate cell mass (IM) of Oellacher. In this report, we have isolated cDNAs encoding zebrafish homologs of the hematopoietic transcription factors GATA-1 and GATA-2 and have used these markers to determine that the IM is formed from mesodermal cells in a posterior-lateral position on the yolk syncytial layer of the gastrula yolk sac. Surprisingly, cells of the IM then migrate anteriorly through most of the body length prior to the onset of active circulation and exit onto the yolk sac. These findings support a hypothesis in which the hematopoietic program of vertebrates is established by variations in homologous migration pathways of extra-and intraembryonic progenitors.

“…The vascular system of teleost embryos is derived from a definite region of the mesoblast called the intermediate cell mass (John, 1932). This intermediate cell mass extends from the level of the anterior kidney into the tail and yolk-sac blood islands (Stockard, 19 1 5;John, 1932). From this intermediate cell mass the vascular system, heart and blood of the embryo are formed.…”

A procedure for obtaining erythrocytes from larval fish for cytological study and a description of larval blood of red hake, Urophycis chuss (Walbaum) and Atlantic mackerel, Scomber scombrus (Linnaeus)

A means of obtaining erythrocytes from larval fish and the blood of larvae of two fish species are described. Erythrocytes were obtained for cytological preparations from larvae of Llroph.vcis chuss (Walbaum) and Scomber scon~brus (Linnaeus) as small as 2.0 mm. Heart and gills were dissected from the larvae, stained, and flattened into a monolayer on a microscope slide. Mature erythrocytes were the only blood cell type observed in either heart or gill preparations, and these appeared to be the same as in the adult fish. Mature erythrocytes can be isolated from formalinfixed larvae, even as sorted from plankton, and prepared for cytological and cytogenetic study and for blood cell counts. Knowledge gained from the study oferythrocytes from larval teleosts can be important in assessing the normalityand health of theseearly-lifestages of fish in either laboratory assays or field studies. The method described is applicable to other fish species. even after years of storage in formalin fixative.
