Description
上記のように、本発明を実施形態によって記載したが、この開示の一部をなす記述及び図面はこの発明を限定するものであると理解するべきではない。この開示から当業者には様々な代替実施形態、実施形態及び運用技術が明らかになるはずである。例えば、図1に示す細胞培養器22に送られる細胞は、単核球に限定されない。細胞培養器22に送られる細胞は、幹細胞、線維芽細胞、あるいは他の体細胞であってもよい。細胞培養器22に送られる細胞は、任意である。
本実施例においては、完全に閉鎖された環境下において、培地交換及びガス交換をすることなく、細胞を培養可能である例を示す。増殖因子を培地(StemSpan H3000、登録商標、STEMCELL Technologies Inc.)に添加し、さらに培地に脱アシル化ゲランガムを添加して、ゲル培地を用意した。
血液を赤血球沈降剤で処理し、赤血球を少なくとも部分的に除去された処理血液を得た。処理血液を表面細胞マーカー抗体で処理し、蛍光活性化セルソーティング(FACS)で分析した結果を図12に示す。処理血液は、CD3陽性細胞、CD14陽性細胞、CD31陽性細胞、CD33陽性細胞、CD34陽性細胞、CD19陽性細胞、CD41陽性細胞、CD42陽性細胞、及びCD56陽性細胞を含んでいた。
