We evaluated the ability of G-CSF to increase the number of hematopoietic s
tem cells obtained by "delayed" BM harvest for allogeneic transplantation.
Five normal donors received G-CSF @ 10mcg/kg/day x 5 followed by repeat PB
and BM assays at day 6 and 16, and BM harvest at day 16. Stem cells were no
t increased in the BM at day 16. Five patients underwent BMT and engrafted
at +10 to +19 days. While the tested strategy offers no intrinsic advantage
s, its potential cannot be evaluated fully without alternative timing and/o
r additional, "early acting" growth factors.
