Brief Summary

Diabetes mellitus is a long-term multi-organ disease with severe implications that constitute a major health problem worldwide. Type 1 diabetes is an autoimmune disorder in which the body's own immune system attacks and destroys the cells that make insulin. Exogenous administration of insulin is the primary method of controlling type 1 diabetes by regulating blood glucose levels, but this treatment does not reverse nor prevent disease progression. Our hypothesis is that when implanting stimulated total bone marrow by arterial injection directly into the pancreas, we will achieve functional recovery of insulin-producing cells. This study will include patients with chronic type 1 diabetes and absence of lesions in target organs. We will follow the evolution of patients receiving autologous total bone marrow implantation by selective catheterization and compare to a non-treatment control group. All subjects will continue to use insulin therapy as needed to maintain the best possible glucose control. The objective is to achieve a significant increase in C-peptide levels indicating a regeneration of the beta islet cells with a decrease in exogenous insulin usage in at least 70% of the patients. This study is a follow-up to our initial study in which 22 patients received autologous total bone marrow. The initial study was 100% safe but additional studies like the one described above are needed to show efficacy.
