  • It functions by slowing or blocking cell growth and compromising the immune system's response. (ijbs.com)
  • Treatment for this condition remains difficult and largely ineffective, because the growth of cells in the wound is inhibited ( 2 ) and chemotherapy usually leads to myelosuppression, the latter of which further compromises the migration of multipotent cells from the bone marrow ( 3 ). (ijbs.com)
  • Growth of most cell lines was improved by the addition of human AB serum and irradiated human bone marrow stromal cells. (edu.au)
  • The effect of bone marrow stromal cells appeared to be caused by a diffusable factor(s), but close cellular interaction could not be excluded since cloning in microwells produced consistent and optimal cell growth compared to growth in soft agar. (edu.au)
