This is often performed to cause cells to express a protein of interest.

The main reason is that very few cells take up the vector and express the gene, so the treatment has little effect.

These cells express goosecoid consistent with their role as the organizer.

This is achieved by making the cells express a gene which creates a pacemaker current.

The host's cells express "self" antigens that identify them as such.

A flow cytometer can be used for the direct analysis of cells expressing one or more specific proteins.

Allows for antibody identification of cells expressing the target protein.

However, research shows that these cells express excitability with changes in the intracellular concentrations of Ca.

If a cell does not express these receptors then the virus cannot normally infect it.

This is likely to be due to many of these 'bad' cells expressing Glis1 but not all four of the reprogramming factors.
