Figure 4. Age-induced gene expression of hematopoietic progenitor cells (HPC).

Figure 4

CD34+ HPC were isolated from cord blood (CB) or from mobilized peripheral blood (PB) of healthy donors (27–73 years). Gene expression profiles revealed that 776 ESTs were significantly age-induced (red) and 704 ESTs were age-repressed (green). We have combined the age-induced gene expression of HPC with replicative senescence data in MSC. The heat map demonstrated here indicates an association between the two data sets.
