Xeno- and serum-free human mesenchymal stromal/stem cell (MSC) expansion medium
PRIME-XV MSC Basal XSFM provides control and consistency over MSC outcomes by enhancing cell growth and viability at every stage of research and development.
Population Doubling Over 14-Day Expansion


Figure 1. PRIME-XV MSC Basal XSFM supplemented with 5% hPL significantly outperforms α-MEM supplemented with 5% hPL. After 14 days of MSC expansion, PRIME-XV MSC Basal XSFM supplemented with 5% hPL (PLTGold-GI, Mill Creek) outperforms αMEM (with nucleosides) supplemented with 5% hPL by ~2 total population doublings (i.e., ~4-fold greater expansion) and αMEM without nucleosides by ~4 total population doublings (i.e. ~16-fold greater expansion).
MSC Expansion Across Four Passages (14 Days of Culture)


Figure 2. PRIME-XV MSC Basal XSFM supplemented with 5% hPL successfully supports expansion of various sources of hMSCs. Over 4 passages of culture, PRIME-XV MSC Basal XSFM supplemented with 5% hPL (PLTGold-GI, Mill Creek) supports reliable expansion of hMSCs across 3 different tissue origins. Each data point represents the average of a single donor, with a total of 3 donors tested per tissue origin.
| Sample | CD73 | CD90 | CD105 | CD34 | CD45 | CD14 | CD19 | HLA-DR |
| BM-MSC | 100.0% | 100.0% | 99.1% | 0.11% | 0.114% | 0.021% | 0.067% | 0.016% |
| AD-MSC | 99.5% | 99.8% | 99.7% | 0.036% | 0.036% | 0.042% | 0.125% | 0.003% |
| UC-MSC | 100.0% | 100.0% | 97.5% | 0.056% | 0.056% | 0.036% | 0.043% | 0.027% |
The surface marker data show the average of 3 different donors for each source of hMSC measured after 4 passages. Positive markers (CD73, CD90, CD105) are maintained, negative markers (CD34, CD45, CD14, CD19, HLA-DR) remained low.
PRIME-XV MSC Basal XSFM is manufactured following GMP using qualified raw materials to ensure continuity of supply and lot-to-lot reliability from our facilities all over the world.
