| 摘要 |
A method is provided, including obtaining a population of isolated immature antigen-presenting cells; enriching a population of isolated stem/progenitor cells within a larger population of cells; activating the population of immature antigen-presenting cells; and following the activating, inducing at least one process selected from the group consisting of: differentiation, expansion, activation, secretion of a molecule, and expression of a marker, by exposing the enriched stem/progenitor cell population to the population of activated antigen-presenting cells. Inducing the at least one process includes generating a lineage specific precursor/progenitor population (LSP) from the enriched stem/progenitor cell population. In addition, (1) obtaining the population of immature antigen-presenting cells includes obtaining the population of immature antigen-presenting cells from umbilical cord blood, and/or (2) enriching the population of stem/progenitor cells includes obtaining the population of stem/progenitor cells from umbilical cord blood. Other applications are also described.
