Abstract:
In order to explore the improvement of seeding efficiencies of infused donor hematopoietic cells to bone marrow in bone marrow transplantation, two recipient groups of syngeneic rat model which received transplanted cells labeled with PKH-26, a red fluorescent membrane dye, by aortic or intravenous administration (2 x 10(7) nucleate cells per recipient rat) respectively, were assayed; at selected times following BMT, partial recipient rat were euthanized and then measured the numbers of PKH-26 labeled cells in recipient rat marrow samples by means of flow cytometry. The results showed that the homing indices of donor hematopoietic cells in aortic group and intravenous group were (14.52 +/- 1.07)% and (10.49 +/- 0.72)% at 30 hours after BMT, respectively (P < 0.05). The results indicated that the number of donor hematopoietic cells localized to recipient bone marrow infused by aortic route is more than that infused by intravenous route.
