cells.

«We have found that the individual
cells within melanoma tumors are not all
identical, and tumors
contain a sub-population of
cells that are inherently drug resistant, which accounts for the fact that advanced melanoma tumors return no matter how much the tumor is depleted,» said Meenhard Herlyn, D.V.M., D.Sc., professor and director of Wistar's Melanoma Research Center.

contain identical genetic material (the genome) yet can have drastic differences in their structural arrangements and functions.

cell in your liver and a
cell in your retina — both
cells contain identical DNA, but very different subsets of proteins are being produced in order to give each
cell its special function.

identical colonies that
contain equivalent populations of V + and V −
cells (Figure 7A, Table 1).
