• Clinically active malignant disease
• Subjects who are receiving ECMO and CRRT currently
• History of known pulmonary embolism or known secondary anti-phospholipid syndrome
• Known or suspected hypersensitivity to any components used to culture the AdMSCs, e.g. BSA and sulfur containing products (e.g., DMSO)
• Known or suspected allergic to diphenhydramine.
• Major trauma or surgery within 14 days of study treatment start
• Mental condition rendering the subject (or the subject's legally acceptable representative[s]) unable to understand the nature, scope and possible consequences of the study
• Alcohol, drug, or medication abuse within one year prior to study treatment start
• Any condition that, in the Investigator's opinion, is likely to interfere with evaluation of the AdMSC therapy or satisfactory conduct of the study
• Irreversible severe end organ failure, such as heart failure/attack, stroke, liver and renal failure due to other disease conditions
