title: Effect of oxygen on the clonal growth of adherent cells (CFU-F) from different compartments of mouse bone marrow.
abstract: We have used collagenase to isolate cell populations from different compartments of mouse bone marrow. Cells were obtained from the shaft of the femur, the endosteum, and compact bone. We have studied the growth-enhancing effects of physiologically low oxygen levels on fibroblast colony-forming unit (CFU-F) growth in vitro. Low oxygen levels (0.1%-10% O2) increased CFU-F formation 1.8- to 2.8-fold. However, cells from the compact bone consistently grew with much higher efficiencies (12- to 31-fold) than did cells from femoral cavity and endosteal areas. These data indicate the usefulness of enzymatic methods of isolating cells from compartments of bone and the use of low oxygen atmosphere to enhance stromal cell growth in vitro.
