title: Regulation of Thy-1 gene expression in transgenic mice.
abstract: Genomic DNA fragments encompassing the human Thy-1 or mouse Thy-1.1 gene have been microinjected into pronuclei of mouse embryos homozygous for the Thy-1.2 allele. In the resulting transgenic mice, the human gene is expressed in a pattern characteristic of normal human tissues, and is not influenced by the pattern of endogenous mouse Thy-1 expression. The mouse Thy-1.1 gene fragment is expressed in a pattern typical of mouse Thy-1, although it is more limited in its distribution. The results indicate the presence of multiple cis-acting regulators of Thy-1 gene expression that have changed in both their character and arrangement over the course of Thy-1 gene evolution.
