Mesenchymal Stem Cells in Patients With Type 1 Diabetes Mellitus

The investigators will acess area under the curve of C-peptide after a liquid mixed meal (Glucerna®), considering the time 0 (basal), 30, 60, 90 and 120 minutes in each follow-up outpatient visit (3 \[T3\], 6 \[T6\], 12 \[T12\], 18 \[T18\], and 24 \[T24\] months after the adipose tissue-derived stem/stromal cells infusion). Other Clinical and Pancreatic Function Evaluation that wil be assess are: Weight, height, body mass index (BMI), blood pressure, heart frequency, frequency of hypoglycemia and insulin dose/kg of body weight, blood count, lipids, renal and hepatic function, thyroid stimulating hormone, free tyroxine, antithyroglobulin antibody, calcium, phosphorus and 25-Hydroxy Vitamin D.
