To Elucidate the Effect of Mesenchymal Stem Cells on the T Cell Repertoire of the Kidney Transplant Patients
A Randomized Trial to Elucidate Effect of Mesenchymal Stem Cells on Immune Modulation in Living Related Kidney Transplant Patients
Despite being a miracle of modern medicine, solid organ transplant recipients are always at risk of rejection, and remain dependent on lifelong immunosuppression. Currently used immunosuppressive drugs suppress the potential of immune system and interfere with the metabolism of medications. Cellular therapies currently being investigated for this purpose require the use of ablative radiotherapy. The investigators are using a less toxic strategy by harnessing the immunosuppressive potential of the MSCs in the Kidney Transplant (KTx) recipients and studying immunomodulation mediated by these cells in the KTx patients.
Hypothesis MSCs interfere with signalling of Immune cells like T cells, B cells and Dendritic cells which leads to improve graft survival of renal transplant patients.
Aim To investigate effect of MSCs on immune cell repertoire in a donor specific mediated response.
The investigators aim to collect peripheral blood from 30 patients (10 patients for autologous cell infusion and 10 for allogeneic (donor derived cell infusion) at various time intervals following MSC therapy. 10 patients serve as controls on standard dose of drugs but without MSC infusion. This peripheral blood would be utilized for isolation of mononuclear cells and performing various immune assays on these cells in a donor specific response.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Autologus Mesenchymal Stem Cells
This group would get two doses of mesenchymal stem cell (MSCs) infusion, one day pre transplant and 30 days post transplant.
These MSCs would be derived from transplant recipient's bone marrow which are cultured in GMP compliant laboratories for 4-6 weeks.
|
These Mesenchymal stem cells are derived from bone marrow of either renal transplant patients or their donors depending upon the group of study.
Other Names:

ACTIVE_COMPARATOR: Allogeniec Mesenchymal Stem Cells
This group would get two doses of mesenchymal stem cell (MSCs) infusion, one day pre transplant and 30 days post transplant.
These MSCs would be derived from transplant donor's bone marrow which are cultured in GMP compliant laboratories for 4-6 weeks.
