Figure 3From: Gene expression in murine mammary epithelial stem cell-like cells shows similarities to human breast cancer gene expressionExpression of stem cell markers in HC11 mammary epithelial cells. (a) CD44 expression. DIC, differential interference contrast allows visualization of the cells. Note that the proportion of CD44-positive cells decreases as the culture differentiates but the intensity of the signal in those cells that are positive remains constant. (b) Keratin 5 and Keratin 8 (Krt 5/8) expression.Back to article page
