Abstract

The levels of thrombospondin 2 (TSP2) and thrombospondin 3 (TSP3) mRNAs in a variety of human tissues were determined by analysis of multiple-tissue mRNA dot blots. For TSP2 mRNA, aorta and fetal heart had the greatest relative abundance. High levels were also detected for muscle, fetal, endocrine, immune, and nerve tissues. The pattern of expression of TSP3 mRNA was very different: kidney, pituitary gland, trachea, uterus, and fetal kidney had the greatest abundance. In general, TSP3 mRNA was expressed at high levels in endocrine, muscle, and fetal tissues. In addition to the tissue-specific differences, a more even distribution of TSP3 mRNA among tissues was observed. The high relative abundance of the two mRNAs in a variety of tissues and the tissue-specific differences in expression could be significant for understanding the diverse roles implicated for TSP2 and TSP3.
