Blastocyst material was obtained from 25 pigs during the period 10 to 33 days post coitum, and fixed thin sections of tissue were hybridized in situ to sense and antisense fos RNA probes synthesized using the expression vector Bluescribe M13. Indirect immunofluorescence using antisera to a synthetic peptide fragment of c-fos was used to confirm the tissue distribution of oncogene-encoded proteins, which were shown by immunoprecipitation to have Mrs of 55,000 and 40,000, which are the known Mrs of the fos gene product and an associated nucleoprotein, respectively. Northern and slot blots were used to assess the distribution of c-fos mRNA and the size of the fos transcript was found to be 2.3 kbases. C-fos was expressed in trophectoderm from blastocysts early in pregnancy but declined with increasing blastocyst development so that it was virtually absent by day 19 of gestation. High levels of fos proto-oncogene expression were, however, retained in the allantoic membranes up to at least day 19 of pregnancy. The expression of the fos protein could be prolonged in trophectodermal cells in monolayer culture by addition of conditioned medium from blastocysts cultured for 2 h, suggesting the presence of a growth-factor-like substance.
