Expression of collagen alpha1(I) mRNA variants during tooth and bone formation in the rat.

Collagen alpha1(I) mRNA is composed of two variants of 5 and 6 kb, differing in the length of the 3' untranslated region. In this work, the nucleotide sequences of the two rat mRNA variants were compared, and their expression pattern in cells forming bone, dentin, and cementum were analyzed. The sequences were determined from cDNA inserts of tooth and bone… CONTINUE READING
