Summary: | To provide a method of manufacturing chimeric antigen receptor-expressing T cells (CAR T cells) from peripheral blood mononuclear cells (PBMCs) from a subject from which a blood sample is obtained.SOLUTION: The manufacturing method comprises a step (a) of obtaining the PBMCs from the blood sample; a step (b) of isolating the PBMCs obtained from the blood sample, by using a membrane filtration system and ammonium chloride-potassium buffer; a step (c) of washing the PBMCs via centrifugation; a step (d) of optionally cryopreserving the PBMCs; a step (e) of optionally thawing the PBMCs cryopreserved in the step (d); a step (f) of washing the PBMCs using a membrane filtration system; a step (g) of manufacturing the CAR T cells from the PBMCs from the step (f); and a step (h) of washing the CAR T cells from the step (g) by using a membrane filtration system.SELECTED DRAWING: None
【課題】血液試料が得られる対象由来の末梢血単核球(PBMC)からのキメラ抗原受容体発現T細胞(CART細胞)の製造方法を提供する。【解決手段】血液試料からPBMCを取得し(工程(a))、前記血液試料から得られた前記PBMCを、膜濾過系及び塩化アンモニウム-カリウム緩衝液を使用して単離し(工程(b))、前記PBMCを遠心分離により洗浄し(工程(c))、場合により、前記PBMCを凍結保存し(工程(d))、場合により、工程(d)で凍結保存した前記PBMCを解凍し(工程(e))、前記PBMCを、膜濾過系を使用して洗浄し(工程(f))、工程(f)の前記PBMCからCART細胞を製造し(工程(g))、そして工程(g)の前記CART細胞を、膜濾過系を使用して洗浄する工程(工程(h))を含む、製造方法とする。【選択図】なし |
