Dye-mediated photolysis of human neuroblastoma cells: implications for
autologous bone marrow transplantation
F Sieber, S Rao, SD Rowley and M Sieber-Blum
Cells from three different human neuroblastoma cell lines and normal human
bone marrow cells were exposed to the lipophilic fluorescent dye,
merocyanine 540 (MC 540), and white light. In vitro clonogenic tumor cells
were inactivated up to 25,000 times more rapidly than multipotent
hematopoietic progenitor cells (CFU-GEMM). It is conceivable that this
pronounced difference in sensitivity to MC 540-mediated photolysis can be
exploited for the selective killing of residual neuroblastoma cells in
autologous remission marrow grafts.
