Study Summary

Anti-rejection medicines, also known as immunosuppressive drugs, are prescribed to organ transplant recipients to prevent rejection of the new organ. Long-term use of these medicines places transplant recipients at higher risk of serious infections and certain types of cancer. The purpose of this study is to determine if: * it is safe to give mesenchymal stromal cells (MSCs) to kidney transplant recipients, and * the combination of the immunosuppressive (anti-rejection) study drugs plus the MSCs can allow a kidney transplant recipient to slowly reduce and/or then completely stop all anti-rejection drugs, without rejection of their kidney (renal) allograft, a process called "immunosuppression withdrawal".

Primary Outcome

Operational tolerance (to their kidney transplant) defined by participant remaining off all immunosuppression for 52 weeks after completion of Immunosuppression Withdrawal (ISW) with: * No evidence of biopsy-proven allograft rejection after initiation of ISW; * Acceptable renal function, defined as an estimated GFR \> 60 ml/min/1.73cm\^2 calculated using the CKD-EPI equation or a serum creatinine that has increased no more than 25% above baseline, as assessed at the week 52 visit after completi
