Fetal bovine sera from each of three different commercial sources were tested for their ability to support cloning of human fibroblastoid cells in vitro and addition of estrogen or hydrocortisone to a culture medium that inhibits growth, with subsequent reversal of the inhibitory effect, implies that these hormones competitively regulate growth of responsive cells in vivo.

Little was learned of what occurred in families where only subclinical infection or undiagnosed disease occurred, and only part of the family infection pattern might be revealed.

On the oncogenic properties of chicken embryo lethal orphan virus, an avian adenovirus.
Summary The oncogenicity of chicken embryo lethal orphan virus for newborn hamsters has been confirmed. Tumor incidence was found to be a function of the titer of the virus inoculum. Fifty-four %…

SV40 tumor extracts are capable of hypermethylating homologous sRNA extracted from normal hamster liver while extracts of normal tissues cannot, and significant incorporation of methyl- 14 C groups was found in the N 1 -methylguanosine of hamster sRNA hydrolysates.
The fine structure of the Yaba monkey tumor poxvirus.

The tissue culture findings are consistent with the hypothesis that the cycle of the Yaba virus may be slower than that of other poxviruses, and regular subunits have been demonstrated on the surface of immature particles.
