A method of collecting embryonic-like stem cells from a placenta which has been treated to remove residual cord blood by perfusing the drained placenta with an anticoagulant solution to flush out residual cells, collecting the residual cells and perfusion liquid from the drained placenta, and separating the embryonic-like cells from the residual cells and perfusion liquid. Exogenous cells can be propagated in the placental bioreactor and bioactive molecules collected therefrom.

1. A method of collecting a cell population comprising, perfusing a post-partum human placenta with a perfusion solution by passing said perfusion solution into one or both of the umbilical artery and umbilical vein of said placenta; and collecting said perfusion solution, wherein said collected perfusion solution comprises a cell population comprising a nucleated placental cell population. 2. The method of claim 1, further comprising isolating the cell population comprising a nucleated cell population from the collected perfusion solution. 3. The method of claim 2, wherein the cell population is isolated by centrifugation of the collected perfusion solution. 4. The method of claim 2, further comprising removing platelets from the cell population, thereby producing an isolated nucleated placental cell population. 5. The method of claim 4, wherein the nucleated cell population is isolated by density gradient centrifugation. 6. The method of claim 4, wherein the collected perfusion solution consists of perfusion solution that has been collected from umbilical vessels. 7. The method of claim 4, wherein the collected perfusion solution comprises perfusion solution that has been collected from umbilical vessels and perfusion solution that has been collected from maternal sites of the placenta. 8. The method of claim 1, wherein the perfusion solution comprises heparin. 9. The method of claim 1, wherein collecting the perfusion solution comprises collection via gravity drainage. 10. The method of claim 1, wherein collecting the perfusion solution comprises collection via aspiration. 11. The method of claim 1, wherein neither said cell population nor said nucleated cell population are combined with cord blood or hematopoietic stem cells from cord blood.
