Fig. 3From: HSP70 mRNA expression by cells of the epithelial rest of Malassez due to mechanical forces in vitroSEM observations. The rounded nuclei and flattened cytoplasm of cultured ERM cells were observed in the control group. Only flattened cells without any nuclear protrusions were observed immediately after the centrifugation and few protrusions of nuclei were observed at 3 h after the centrifugation.
