FIG. 4.

Multicolor FACS analysis was done to determine the presence of MSCs (CD34⁻73⁺90⁺105⁺) in DD samples. (A) DD-derived P0 cells were labeled as described in the legend of Fig. 5. Shown here are mean %±SD of CD34⁻73⁺90⁺105⁺ cells. Data were pooled from 10 patients. (B) Cumulative data from 15 DD and 8 CT patients comparing fresh cells (FC) to P5 cells for CD34⁻73⁺90⁺105⁺ cells. Except for Skoog's fibers (internal control), all other cells showed significant increase in CD34⁻73⁺90⁺105⁺ cells in passages up to P5 (*P<0.05, **P<0.01). P0, passage 0 (and so on); MSCs, mesenchymal stem cells.
