Explanation:

In general, these cells are seen with eosin and hematoxycillin, with which, their internal media will be more basophilic, with more violet staining since they have a high protein load in their interior due to the great genetic load.

During cell division, the genetic load increases because the amount of material is doubled to give a daughter cell.
