cell surface proteins is an organized attempt to catalog these cell
VetBooks.ir surface proteins.

Two otherwise identical cell populations may be distinguished
by the set of cell surface molecules they express. In identifying cells

in this way, it is possible not only to identify cell subpopulations
but also to follow cell development and differentiation as different
genes are turned on and off depending on changes in the cell's
function.

In many cases it has proven possible to identify cell
subpopulations or changes in a cell's phenotype without
determining the cell's functional significance. Different phenotypes
occur in different domestic animal species. Students will therefore

find much of the literature in this area confusing, especially if large
numbers of CD molecules are reported for a specific cell
phenotype.
