STEMCELL Technologies StemSpan StemSpan-ACF Erythroid Expansion Medium
- 研究用
StemSpan™-ACF Erythroid Expansion Medium(ACF-E)(ST-09860)は、ヒト造血細胞をin vitroで培養し増殖させる培地です。組換えタンパク質と合成成分のみが含まれており、血清やその他のヒトまたは動物由来の成分が含まれない、動物性成分フリー(Animal Component-Free, ACF)の組成です。
本品に、100倍濃縮サプリメントのStemSpan™ Erythroid Expansion Supplement(ST-02692)を添加すると、ACF条件下でヒト造血前駆細胞を拡大培養し、CD71+およびGlycophorin A+の赤芽球に分化させることができます。
製品の特長
StemSpan™-ACF Erythroid Expansion Mediumで、ヒト赤血球細胞を動物性成分フリーで増殖
- 赤血球前駆細胞の増殖・分化向けに特化した、動物性成分フリー培地
- StemSpan™ Erythroid Expansion Supplementを添加しての使用に最適
- CD34+細胞1個のインプットあたり、数千個のCD71+GlyA+赤血球細胞を産生
データ紹介
Erythroid Expansion Supplementを添加した各種StemSpan培地をもちいて、ヒト臍帯血CD34陽性細胞から産生した赤血球細胞

(A) Average numbers of erythroid cells generated after culturing purified CD34+ CB cells (n = 5) for 14 days in StemSpan™ SFEM (black bars), SFEM II (grey bars), or StemSpan™-ACF Erythroid Expansion Medium (ACF-E, orange bars) media containing StemSpan™ Erythroid Expansion Supplement (Catalog #02692). Shown are the number of erythroid cells that express CD71 and/or Glycophorin A (GlyA) per input CD34+ cell. (B) The percentages of the different erythroid cell subsets generated in these cultures are shown, including CD71+GlyA+ erythroblasts, immature CD71+GlyA- erythroid progenitor cells and pro-erythroblasts, and CD71-/lowGlyA+ normoblasts. All three media supported the generation of thousands of erythroid cells per CB-derived CD34+ cell plated.

Yields and percentages of erythroid cells produced after culturing purified CD34+ CB cells (n = 5) for 14 days in StemSpan™ SFEM, SFEM II or ACF-E media containing Erythroid Expansion Supplement. Erythroid cells were identified by flow cytometry after staining with antibodies against CD71 and GlyA. The % erythroid cells represent the percentage of cells that express CD71 and/or GlyA. *CI: Confidence Interval.
