abstractText | The expression of IFN-alpha transcripts was investigated in murine embryos, fetuses, and fetal annexes in mid and late pregnancy. We have shown by Northern blot analysis, reverse transcription-polymerase chain reaction, and in situ hybridization the presence of IFN-alpha transcripts in mouse placenta, fetus, and newborn. From the 14th day of gestation until birth, a typical IFN-alpha transcript (1.2 kb) is found in the fetus. A transcript of larger size (2.2 kb) appears near birth and is present in the newborn mouse. Fetal annexes between the 10th and 21st days of gestation also express IFN-alpha. From the 10th day until birth, the 1.2-kb IFN-alpha mRNA species is present, as well as unusually large transcripts: 4 and 7 kb. To localize IFN-alpha transcripts, in situ hybridization was performed, using 35S-IFN-alpha antisense RNA probe in comparison with the sense RNA probe. The tissue pattern of IFN-alpha transcription in fetuses shows a clear labeling of many epithelia, such as skin, ependyme, and intestine glandular epithelium. A possible relation with cellular differentiation is discussed. |
