Cells derived from CD34⁺ cells that were cultured in the presence of tumor-conditioned medium reorganize into cord structures on Matrigel. CD34⁺ cells were seeded under conditions to support myeloid cell growth (GM–CSF and SCF) in the presence or absence of 40% tumor-conditioned medium. After 7 days, they were detached and seeded onto Matrigel-coated wells. After 24 h, CD31⁺ cells were detected by immunocytochemical staining
