RNAs from a number of cells, including platelets, were analyzed by Northern blotting
for the presence of transcripts to four platelet proteins - actin, thrombospondin,
fibronectin, and platelet factor 4. RNA from platelets contains considerable amounts
of mRNA for platelet factor 4, easily detectable mRNA for actin, and traces of mRNA
for thrombospondin. mRNA for platelet factor 4 was not detected in human lymphocytes
or in any of 5 human cell lines.
