Method for preparing therapeutic agent

Abstract

A bone marrow fluid of a patient is sampled, housed in a collection tube 11 and conveyed into an isolator in a sterile state. In the isolator, the bone marrow fluid in the collection tube is pipetted into test tubes and culture tube, etc. To the bone marrow fluid in the tubes, an erythrocyte sedimentation agent is added. After precipitating erythrocytes, the supernatant is collected. From the collected supernatant, a bone marrow cell-containing fraction for liver regeneration is concentrated and pipetted into flasks which are conveyed into an incubator to start the cell-culture. From the isolator system, test tubes are taken out. The bone marrow fluid in the test tubes and the concentrate are subjected to a safety test, etc.
