Overview
When added to serum-free medium, StemSpan™ CC100 promotes the expansion of CD34+ cells isolated from human cord blood and bone marrow, and is recommended if high cell yields and large numbers of CD34+ cells are desired.
We recommend using StemSpan™ CC100 in combination with any of the following StemSpan™ media:
• StemSpan™ SFEM (Catalog #09600)
• StemSpan™ SFEM II (Catalog #09605)
• StemSpan™-XF (Catalog #100-0073)
• StemSpan™-AOF (Catalog #100-0130)
• Recombinant human stem cell factor (SCF)
• Recombinant human interleukin 3 (IL-3)
• Recombinant human interleukin 6 (IL-6)
Data Figures

Figure 1. Expansion of CD34+ Human Cord Blood Cells in StemSpan™ Media Containing CC100 Cytokine Cocktail
Purified CD34+ human cord blood (CB) cells were suspended at a concentration of 10,000 per mL in StemSpan™ SFEM (dark gray bars), SFEM II (blue bars) and AOF (orange bars) media containing CC100 Cytokine Cocktail (Catalog #02690). Cultures were maintained for 7 days, after which the cells were counted and examined for CD34 and CD45 expression by flow cytometry. Shown are the fold expansion of total nucleated cells (TNC) (A) and CD34+ cells (B) per input CD34+ cell, and the percent CD34+ cells (C). Results represent the average of 32 different CB samples. Vertical lines indicate 95% confidence limits, the range within which 95% of results fall. The numbers of cells produced in StemSpan™ SFEM II were significantly higher than in StemSpan™ SFEM and StemSpan™-AOF (*P<0.001, paired t-test, n=32).
Note: Data for StemSpan™-AOF shown were generated with the original phenol red-containing version StemSpan™-ACF (Catalog #09855). However internal testing showed that the performance of the new phenol red-free, cGMP-manufactured version, StemSpan™-AOF (Catalog #100-0130) was comparable.

Figure 2. StemSpan™ SFEM II Serum-Free Expansion Medium Containing CC100 Cytokine Cocktail Supports Greater Expansion of Human CD34+ Cells Than Other Media Tested
Expansion of CD34+ cells, normalized relative to the values obtained in StemSpan™ SFEM medium (dark gray bars) after culturing purified CD34+ CB (A, n=6) or bone marrow (BM) (B, n=3) cells for 7 days in StemSpan™ SFEM, SFEM II (blue bars) and AOF (orange bars), and six media from other commercial suppliers (light gray bars, Commercial Alternative 1-6, which included, in random order, StemPro34 (Life Technologies), X-Vivo-15 and HPGM (both from Lonza), SCGM (Cellgenix), StemLine II (Sigma) and HP01 (Macopharma)). All media were supplemented with StemSpan™ CC100 Cytokine Cocktail (Catalog #02690). Vertical lines indicate 95% confidence limits, the range within which 95% of results fall. The numbers of CB and BM cells produced in StemSpan™ SFEM II were significantly higher than in all other media, except the numbers of CB cells produced in StemSpan™-AOF (*p<0.05, paired t-test).
Note: Data for StemSpan™-AOF shown were generated with the original phenol red-containing version StemSpan™-ACF (Catalog #09855). However internal testing showed that the performance of the new phenol red-free, cGMP-manufactured version, StemSpan™-AOF (Catalog #100-0130) was comparable.
