allogeneic amniotic mesenchymal stem cell therapy for lupus nephritis

Conditions: Lupus Nephritis; Mesenchymal Stem Cells

Summary: this study would further evaluate the safety and efficacy of human amniotic mesenchymal stem cell (ha-msc) for the treatment of lupus nephritis (ln).

eleven patients with who class iii, iv or v ln were given ha-msc (peripheral intravenous infusion, dose 1×106/kg cells, once every month for three times). at the same time, five patients with ln who were not given ha-msc as the blank control group. all patients did not received intravenous corticosteroids pulse therapy, but the use of oral corticosteroids and intravenous cyclophosphamide, or oral mycophenolate mofetil, tacrolimus , leflunomide were allowed.

Eligibility criteria:
