I strongly recommend CD44 variant isoform 8-10 (CD44v), which is highly expressed not only cancer stem-like cells but also normal epithelial cells including insulin-secreting beta-cells and sebaceous gland cells. As compared with pan CD44, CD44v is highly and specifically expressed in epithelial cells.
