this cells should be stem cell transplant, so homing is the environment that accept them and nourish them with growth factors to mature

This homing phenomenon may be related to tumour cell recognition of specific “exit sites” from the circulation or to awareness of a particularly favourable—or forbidding—“soil” of another tissue. This may occur because of an affinity that exists between receptor proteins on the surface of cancer cells and molecules that are abundant in specific tissues.

Metastasis is defined by distant spread via blood/lymphatics --> binding to endothelium --> extravasation & homing.

Since metastasis to only one organ has been affected, it's safe to say this liver cell surface antibody has affected "homing" towards the liver.
