I don't understand your question. A diploid cell is a cell wich have, in its nucleus, some pairs of chromosoms. This is different from a haploid cell, in which the chromosomes are"single".
The organism of a mammal is diploid. All the cells are diploid, except the gamets, which are haploid. So if this is your question, I can tell you that in a mammal, a diploid cell is not a "specific cell" since all the somatic cells are diploid.
