Jagged2 induces a T-lineage specific gene program. Kinetic and quantitative RT-PCR analysis of human CD34⁺lin⁻ CB cells after coculture on OP9-control, OP9-DLL1, OP9-DLL4, OP9-JAG1, or OP9-JAG2 stromal cells. Cells were analyzed at different time points, as indicated in the x-axis. Units of expression are given relative to β-actin and relative to levels in the purified starting population. Data show the average of 2 sets of independent samples. Errors bars represent SEM.
