Functionally different tenascin (TN) isoforms. containing varying numbers of a 9 I amino-acid motif resembling the fibronectin type-Ill homology repeat, may be generated by alternative splicing of the TN primary transcript. In fact, only the TN isoform containing the alternatively spliced region can

Abstract
Northern blot analysis of TN mRNA from different human tissues shows two major bands of about 6 and 8 kb which correspond to two different mRNAs generated by alternative splicing of the primary transcript. In liver, pancreas and kidney only the 6 kb TN mRNA was detectable. The highest levels of 8 kb TN mRNA were observed in placenta and skin representing 30% and 52% of total TN mRNA, respectively. In all other tissues tested the 8 kb TN mRNA represented less than 20% of total TN mRNA.
