Primary Outcome Measures :
  1. The primary safety endpoint in this study is; safety parameters include adverse events, hypoglycemia and allergic reactions [ Time Frame: 372 days ]
    To investigate the safety and tolerance after a repeated allogeneic infusion of Whartons Jelly Mesenchymal Stromal Cells (WJMSCs) intravenously in adult patients diagnosed with type 1 diabetes after one year following the repeated treatment.

  2. Delta-change of C-peptide AreaUnder the Curve (AUC) (0-120 min) for Mixed Meal Tolerance Test (MMTT) at day 372 following WJMSC infusion when compared to test performed before start of treatment. [ Time Frame: 372 days ]

Secondary Outcome Measures :
  1. Number of patients insulin independent (ADA criteria) at day 372. [ Time Frame: 372 days ]
  2. Number of patients with daily insulin needs <0.25U/kg at day 372. [ Time Frame: 372 days ]
  3. HbA1c at day 372 [ Time Frame: 372 days ]
  4. Glucose variability (mean amplitude of glycaemic excursions and glycaemic lability index) duration derived from the continuous glucose monitoring system® at day 372 [ Time Frame: 372 days ]
  5. Delta change of levels of fasting C-peptide at day 372 when compared to test before start of treatment [ Time Frame: 372 days ]
  6. Numbers of patients with peak C-peptide >0.20 nmol/l, in response to the MMTT, at day 372. [ Time Frame: 372 days ]
