Immunohistochemical analysis of livers from VhlloxP/loxP (a), PtenloxP/loxP (b), and VhlloxP/loxP;PtenloxP/loxP (c) mice using an antibody against the proliferation marker Ki-67. d Quantification of the number of positive cells per high power field of the liver (×400). One field per liver section was counted and the data represent mean ± standard deviation. * Statistically significant difference between VhlloxP/loxP;PtenloxP/loxP and all other genotypes (P < 0.01, student's t test). Magnification, ×200 (a through c)
