In vitro chick embryo cell response to strain MC29 avian leukosis virus.

Strain MC29 avian leukosis (myelocytomatosis) virus induced infection, elaboration of virus, and morphological alteration in chick embryo cells in vitro. Virus liberation began within 18 hr, morphological change was detectable at about 40 hr, and the cultures could be completely altered within 80 hr after infection. Altered cells were about half the volume and grew at approximately twice the rate of uninfected elements.
