p44 Functions in Prostate Epithelial Cells Figure 8. Cytoplasmic p44 inhibited the temperature-dependent differentiation of prostate epithelial cells. LTts-ECs (panels a-l) or LTts- ECs expressing NES-p44 (panels m-t) were grown at 33uC (1st and 3rd panels) or 37uC (2nd, 4th, 5th, and 6th panels) and immunostained with anti-CK18 (1st, 2nd, and 6th panels) or -p44 (3rd, 4th, and 5th panels). Nuclei were stained with Sytox green. doi:10.1371/journal.pone.0049173.g008 PLOS ONE | www.plosone.org 11 November 2012 | Volume 7 | Issue 11 | e49173
