Lack of effect of granulocyte-macrophage colony-stimulating factor on secretion of interferon-tau, other proteins, and prostaglandin E2 by the bovine and ovine conceptus. Academic Article uri icon

abstract

  • Three experiments tested the effects of recombinant bovine granulocyte-macrophage colony-stimulating factor (rbGM-CSF) on the preimplantation bovine and ovine conceptus. There was no effect of rbGM-CSF on the secretion of total radiolabeled protein in conditioned medium, immunoreactive interferon-tau (IFN tau), antiviral activity, or prostaglandin E2 from Day 16-18 bovine conceptuses cultured for 24 hr with, [3H]leucine and +/- 10 ng/ml rbGM-CSF. Similarly, there was no effect of 1 ng/ml rbGM-CSF on the secretion of total radiolabeled protein. IFN tau, or antiviral activity from Day 17 ovine conceptuses. There was also no beneficial effect of 1 or 10 ng/ml rbGM-CSF on the presence of immunoreactive IFN tau in conditioned medium from in vitro-produced bovine blastocysts at Day 7-8 after fertilization. Results indicate that IFN tau secretion from bovine and ovine conceptuses are unresponsive to rbGM-CSF at the concentrations tested.
