Abstract

The initiation, growth, recurrence and metastasis of solid tumours, including oral squamous cell carcinoma (OSCC), have been related to the behaviour of a small subpopulation of 'tumour-initiating' cells. These cells, also called as cancer stem cells, drive tumour growth and are responsible for tumour aggressiveness and therapeutic resistance. One such targeted therapy of importance for the treatment of OSCC, Cetuximab, is anticipated to work by blocking the EGF receptor function of CSCs. Despite the substantial evidence concerning the central role of CSCs in malignant grow, very little is known about their responses to targeted therapies. The main purpose of the present study is to evaluate the effects of Cetuximab on CSC and non-CSC isolated based on their CD44 expression by Fluorescence-ativated Cell Sorting through analysis of their growth rates, apoptotic responses, and loss of stem cell properties.
