The expression pattern of transforming growth factor beta (TGFβ) isoforms in chicken embryo gonads was studied at 6-10 days of incubation. TGFβ2 mRNA was expressed predominantly in the cortex of the left ovary from day 8 of incubation onwards. TGFβ3 mRNA was not detected at any of the stages studied. Similarly, immunofluorescence for the TGFβ protein(More)
Piscirickettsia salmonis is a pathogenic bacteria known as the aetiological agent of the salmonid rickettsial syndrome and causes a high mortality in farmed salmonid fishes. Detection of P. salmonis in farmed fishes is based mainly on molecular biology and immunohistochemistry techniques. These techniques are in most of the cases expensive and time(More)
In airway smooth muscle (ASM), adenosine 5′-triphosphate (ATP) induces a relaxation associated with prostaglandin production. We explored the role of K+ currents (I K) in this relaxation. ATP relaxed the ASM, and this effect was abolished by indomethacin. Removal of airway epithelium slightly diminished the ATP-induced relaxation at lower concentration(More)
Cadherins are adhesion molecules that play a crucial role in tissue morphogenesis. Studies on N-cadherin and E-cadherin in the ovary of fetal hamster suggest that these adhesion molecules are involved in primordial follicle formation. In chicken embryo, present results demonstrate that N-cadherin is located on the surface epithelium and in the cortical(More)
Site-finding of 14-day-old Echinostoma revolutum from the domestic chick was studied by inoculating single worms into various sites on the chorioallantoic membrane (CAM) of 13-day-old chick embryos. Regardless of the site of inoculation, single worms were attracted significantly to the area of the CAM above the embryo. More worms were found in this site at(More)
