Cell-Tracking Model System, Transgenic For Marker Variants

The present invention relates to a cell-tracking model system comprising - a donor harbouring a marker ("donor marker") or being capable of expressing said donor marker, said donor harbouring said donor marker or cells of said donor capable of expressing the donor marker being transferable to a recipient animal; and - a recipient animal which is tolerant against a marker which is an immunologically neutral variant of the donor marker ("recipient marker"), said recipient marker being encoded in the genome of the recipient animal in a form being capable of expression of said recipient marker and said recipient marker being physicochemically or biologically distinguishable from the donor marker.
