Summary The purpose of this study was to determine the ability of human placental stromal cells (PLSC) to support the survival and growth of CD34+ cells. To address this goal, PLSCs were isolated from human full term placenta. CD34+ cells were isolated from human umbilical cord blood (UCB) mononuclear cells (MNC) and co-cultured with primary PLSCs and several PLSC lines. Culture of human UCB CD34+ stem cells with PLSC resulted in the self renewal, proliferation, and differentiation of colony forming unit-granulocyte erythroid megakaryocyte monocyte (CFU-GEMM) and colony forming unit-granulocyte monocyte (CFU-GM) progenitor cells. Location of the growth of CD34+ cells co-cultured with PLSCs was analyzed. In addition, humoral factors produced by the PLSCs were examined for ability to support the growth and survival of CD34+ progenitor cells. Finally, the ability of PLSCs to support the survival and growth of CD34-I- progenitor cells in serum free conditions was tested. Collectively, these results support the hypothesis that the human placenta contains distinct stromal cells with varying abilities to support the self-renewal, proliferation and differentiation of CD34+ progenitor cells.
