"Proliferative potential" refers to the ability of cells or organisms to divide and multiply rapidly, leading to an increase in their numbers.
Full definition
The strict limit in
proliferative potential of normal human somatic cells - a process known as replicative senescence - is highly relevant to the immune system, because clonal expansion is fundamental to adaptive immunity.
The third type of clone, the meroclone, contains a mixture of cells of
different proliferative potential and is a transitional stage between the holoclone and the paraclone (3).
