  • StemSpan™ SFEM
  • Serum-free medium for culture and expansion of hematopoietic cells
  • 产品描述
  • StemSpan™ Serum-Free Expansion Medium (SFEM) has been developed and tested for the in vitro culture and expansion of human hematopoietic cells, when the appropriate growth factors and supplements are added. This allows users the flexibility to prepare medium that meets their requirements. When combined with the appropriate cytokines, SFEM has been used for the culture and expansion of hematopoietic cells isolated from other species, including mouse, non-human primate, and dog. SFEM has also been used for culture of various other hematopoietic and non-hematopoietic cell types. Using appropriate StemSpan™ Expansion Supplements, SFEM may be used to expand CD34+ cells isolated from human cord blood, mobilized peripheral blood, or bone marrow samples, or to expand and differentiate lineage-committed progenitors to generate populations of erythroid, myeloid, or megakaryocyte progenitor cells.

    Data

  • Figure 1. Expansion of CD34 + Human Cord Blood Cells Cultured 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 (gold bars) and ACF (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 results 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™-ACF (*p<0.001, paired t-test, n=32).
  • 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 (gold bars) and ACF (orange bars), and six media from other commercial suppliers (light gray bars, Competitor 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™-ACF (*p<0.05, paired t-test).
  • Figure 3. Expansion of CD34 + Human Cord Blood Cells Cultured in StemSpan™ Media Containing CD34 + Expansion Supplement
  • 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 (gold bars) and ACF (orange bars) media containing CD34 + Expansion Supplement (Catalog #02691). Cultures were maintained for 7 days, after which the cells were counted and examined for CD34 and CD45 expression by flow cytometry. The number of colony-forming units (CFU) in the expanded population was determined by replating cells in MethoCult™ H4435 and counting the number of colonies produced 14 days later. Shown are the fold expansion of total nucleated cells (TNC) (A), CD34 + cells (B) and CFU numbers (C) per input CD34 + cell, and the percent CD34 + cells (D) in these cultures (n=6). Vertical lines indicate 95% confidence limits, the range within which 95% of results fall. The numbers of cells produced in StemSpan™ SFEM II was significantly higher than in SFEM and ACF (*p<0.001, #p<0.05, paired t-test, n=6).
  • Figure 4. StemSpan™ SFEM II Serum-Free Expansion Medium Containing CD34 + Expansion Supplement Supports Greater Expansion of Human CD34 + Cells Than Other Media Tested

All media were supplemented with the StemSpan™ CD34 + Expansion Supplement (Catalog #02691). 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 all other media (*p<0.01, paired t-test, n=6).
