Abstract (original English)

Background aims Stem cell therapy (SCT) is now the up-coming therapeutic modality for treatment of type 1 diabetes mellitus (T1DM). Methods Our study was a prospective, open-labeled, two-armed trial for 10 T1DM patients in each arm of allogenic and autologous adipose-derived insulin-secreting mesenchymal stromal cells (IS-AD-MSC)+bone marrow-derived hematopoietic stem cell (BM-HSC) infusion. Group 1 received autologous SCT: nine male patients and one female patient; mean age, 20.2 years, disease duration 8.1 years; group 2 received allogenic SCT: six male patients and four female patients, mean age, 19.7 years and disease duration, 7.9 years. Glycosylated hemoglobin (HbA1c) was 10.99%; serum (S.) C-peptide, 0.22 ng/mL and insulin requirement, 63.9 IU/day in group 1; HbA1c was 11.93%, S.C-peptide, 0.028 ng/mL and insulin requirement, 57.55 IU/day in group 2. SCs were infused into the portal+thymic circulation and subcutaneous tissue under non-myelo-ablative conditioning. Patients were monitored for blood sugar, S.C-peptide, glutamic acid decarboxylase antibodies and HbA1c at 3-month intervals. Results Group 1 received mean SCs 103.14 mL with 2.65 ± 0.8 × 10(4) ISCs/kg body wt, CD34+ 0.81% and CD45-/90+/73+, 81.55%. Group 2 received mean SCs 95.33 mL with 2.07 ± 0.67 × 10(4) ISCs/kg body wt, CD34+ 0.32% and CD45-/90+/73+ 54.04%. No untoward effect was observed with sustained impr
