In this study, the expression of extracellular matrix genes by vascular cells from human iliac blood vessels was characterized on the mRNA steady-state level by slot blot and Northern transfer analyses, as well as by in situ hybridization. Endothelial cells were isolated from adult human iliac arteries and veins, as well as from umbilical veins; smooth muscle cells were isolated from adult human iliac arteries and inferior vena cava. The results show that confluent umbilical vein endothelial cells expressed the genes that encode types I, III, IV and VI collagens, as well as fibronectin and laminin. In contrast, the iliac endothelial cells expressed the genes for types IV and V collagens, fibronectin and laminin; mRNA transcripts for types I, III and VI collagens were not detectable. The smooth muscle cells from iliac arteries or inferior vena cava displayed gene expression for types I, III, IV, V and VI collagens, fibronectin and laminin. The results indicate major differences in gene expression for the various types of collagens by human iliac endothelial and smooth muscle cells. Furthermore, the fetal-derived umbilical endothelial cells displayed differential collagen gene expression from that of adult iliac endothelial cells.

D009693 Nucleic Acid Hybridization Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
