11. Significant liver disease, defined as persistently elevated AST and/or ALT levels > 2 x ULN (Upper Limit of Normal range)
12. Malignant or pre-malignant haematological conditions
13. Any uncontrolled medical condition or concurrent disease that could interfere with the study objectives
14. Any condition which, in the judgement of the Investigator, would place the subject at undue risk
15. Ongoing treatment with systemic immunosuppressive drugs at inclusion (despite corticoids lower than 10 mg)
16. Participation in another clinical trial during the study or within 28 days prior to planned study entry
17. Exposure to an investigational product during the study or within 28 days prior to planned study entry
18. Female patients of child-bearing potential with a positive pregnancy test at enrolment and F01
19. Female patients who are breast-feeding

20. All female patients of child-bearing potential* UNLESS:

    1. The patient is willing to maintain a highly effective method of birth control** for the duration of the study
    2. The career, lifestyle, or sexual orientation of the patient ensures that there is no risk of pregnancy for the duration of the study (at the discretion of the Investigator)
21. Psychological, familial, sociological or geographical factors potentially hampering compliance with the study protocol and follow-up visit schedule
22. Any form of substance abuse, psychiatric disorder, or other condition that, in the opinion of the Investigator, may invalidate communication with the Investigator and/or designated study personnel

23. Patients unable to freely give their informed consent (e.g. individuals under legal guardianship).

    Criteria specific to the infusion of the ATDC_Nantes:

24. Any pro-coagulant disposition, as evidenced by a past history of thromboembolic disease or abnormal laboratory coagulation parameters which, in the judgement of the Investigator, would place the subject at undue risk
25. Any condition resulting in a substantial reduction in the volume of the pulmonary vasculature or an increase in the pulmonary vascular resistance. Any disease or disease process leading to substantially elevated pulmonary arterial pressure (as evidenced by electrocardiography, echocardiography, radiology or cardiac catheterisation) or right heart hypertrophy or dysfunction
26. Known atrial or ventricular septal defects posing a risk of paradoxical embolism of infused cells or cell aggregates
27. Known hypersensitivity to any component of the cell product or components used in the manufacture of the cell product.

Exclusion Criteria:

1. Genetically identical to the prospective organ recipient at the HLA loci (A.B.DR 0 mismatch)
2. Exposure to any investigational agents at the time of kidney donation, or within 28 days prior to kidney donation
3. Any form of substance abuse, psychiatric disorder, or other condition that, in the opinion of the Investigator, may invalidate communication with the Investigator and/or designated study personnel
