Light and electron microscopic observation of presumptive erythropoietic foci in the medaka yolk sacs.
نویسندگان
چکیده
The medaka, Oryzias latipes is a useful animal model for the study of primary vasculature in vertebrate embryos. Using benzidine stain for erythroid cells, we found presumptive erythropoietic foci in the yolk sac vitellolysis zone at stage 39. These foci were present in the yolk syncytial layer, in the extravascular and vitellolysis zone from 9 days post fertilization (dpf) to 11 dpf, and then declined between 12 to 13 dpf with yolk mass depletion. A table of previous reports on various species of fish showing yolk sac erythropoiesis is also presented.

Histochemical study of the definitive erythropoietic foci in the chicken yolk sac.
It is well known that avian yolk sac is involved in both primitive and definitive erythropoiesis during embryonic development. Definitive erythropoiesis is first detected at about 4-5 days incubation and its maximum activity is reached between day 10 and 15 of incubation, ending between days 18 and 20 of incubation. We confirmed the definitive erythropoietic foci in the chicken yolk sac through...
متن کاملElectron microscopic evidence of flagella and pili on Legionella pneumophila.
Twenty-one strains of Legionella pneumophila, representing the six known serotypes of the organism, cultured on various bacteriological media and in the yolk sacs of fertile hens' eggs were examined by negative stain electron microscopy for flagella and pili. These appendages were usually observed after cultivation on media capable of inducing an early profuse growth of the organisms.
متن کاملLight and electron microscopic study of the tongue in the White-eared bulbul (Pycnonotus leucotis)
The aim of the present study was to investigate the light and electron microscopic structure of the tongue in White-eared bulbul (Pycnonotus leucotis). Six adult White-eared bulbul (3 males and 3 females) in Shahrekord district were used in the investigation. Samples of the apex, body and root of the tongue were prepared routinely for light and electron microscopic study. Results showed that th...
متن کاملHistological Analyses Demonstrate the Temporary Contribution of Yolk Sac, Liver, and Bone Marrow to Hematopoiesis during Chicken Development
The use of avian animal models has contributed to the understanding of many aspects of the ontogeny of the hematopoietic system in vertebrates. However, specific events that occur in the model itself are still unclear. There is a lack of consensus, among previous studies, about which is the intermediate site responsible for expansion and differentiation of hematopoietic cells, and the liver's c...
متن کاملRuptured yolk sacs and visceral fungi in emergent pink salmon alevins: histopathology and relation to marine survival.
Marine survival of anadromous salmon species is highly variable, and causes of this variability are often unknown. In the 1990s, cultured pink salmon Oncorhynchus gorbuscha alevins from 2 different regions in Alaska, USA, had years with increased postemergent mortality that could not be attributed to viruses, bacteria, or parasites. In both regions, lifetime marine survival of the most severely...
