The mitotic activity was determined under the inverted phase contrast microscope and the number of mitotic cells was counted. Our results showed that the mitotic cells decreased in endothelial cell culture with thalassemic serum as compared with normal human serum, autologous umbilical cord serum or fetal bovine serum. The percentage of mitotic cells decreased on day 3 in the presence of β-thalassemia/HbE serum from both splenectomized and non-splenectomized patients as compared with normal or autologous umbilical cord serum. In the presence of α-thalassemic serum, a similar outcome was also observed. From this study we can conclude that the thalassemic sera might contain factors which affect the endothelial cell growth and proliferation by inhibiting mitosis in vitro.Mahidol UniversityMedicineArticleSCOPUS
