Anchor Cell invasion

A model for the initiation of tumor cell metastasis

Cell invasion is an initiating event during tumor cell metastasis and an essential process during development. During vulval development, the uterine anchor cell (AC) breaches two basal laminae that separate the uterus from the epidermis and invades the underlying vulval epithelium. We are investigating the signals, by which the vulval precursor cells induce the anchor cell to invade into the vulval epithelium.
