Liquid storage of bone marrow.

A program of nonfrozen autologous bone marrow rescue was used to treat patients with refractory nonhematological neoplasms. In vitro storage of bone marrow cells and CFU-C suggests that storage at 4 degrees or 10 degrees for periods up to five days can be undertaken with only minor loss of CFU-C. However, since the loss occurred in a gradual fashion, shorter duration of storage would probably be better. Hematological recovery after high dose chemotherapy occurred faster in patients given more CFU-C and those with shortest duration of storage prior to reinfusion.
