Often it is desirable to express eukaryotic genes in prokaryotic cells.

GAL4 is then only expressed in cells where the driver gene is usually active.

Two genes are expressed in macrophages and 6 in glial cells.

Toc1 gene is expressed in most plant structures and cells, and has its locus on chromosome 5.

The gene is expressed in hemopoietic, endothelial and epithelial cells.

The short form was found to be expressed in cells during growth but is rapidly repressed during starvation.

It is primarily expressed in epithelial cells however its function is poorly understood.

P2X receptors are expressed in cells from a wide variety of animal tissues.

However, in most cases it cannot be ruled out that such proteins are indeed expressed in certain cells or under certain circumstances.

The human Thy-1 gene which is expressed in neuronal cells in vivo(25) was used as a control.
