Figure 2.

Flow-cytometric evaluation of the reserves and survival characteristics of BM progenitor and erythroid precursor cells before and after lenalidomide therapy. The left bars represent the mean proportion (± SEM) of BM CD34⁺ progenitor and CD36⁺/GlycoA⁺ and CD36⁻/GlycoA⁺ erythroid precursor cells before and after treatment. The right bars represent the mean proportion (± SEM) of apoptotic (7AAD^dim) cells within the CD34⁺, CD36⁺/GlycoA⁺ and CD36⁻/GlycoA⁺ cell compartments before and after therapy. Results were compared using the Student’s t test for paired samples and P values are indicated. SEM: standard error of the mean.
