Overview
Type 1 Diabetes is a chronic autoimmune disease. It results from autoimmune destruction of pancreatic Beta cells leading to absolute insulin insufficiency. The establishment of pluripotent like human stem cells derived from adipose tissue derived mesenchymal cell origin have introduced a new potential source for cell therapy in type 1 diabetic patients, especially in light of recent successes in producing glucose-sensitive insulin secreting cells and this will be the scope of this study. In the last decade, human clinical trials of introducing insulin producing stem cells from various origins were approved and conducted.
Description
Differentiation of stem cells from various sources to form insulin-producing cells (IPCS) provides a new and promising strategy to reconstitute pancreatic endocrine function. Studies recently developed a multistep differentiation technique for the differentiation of human embryonic stem cells to form pancreatic progenitors. At the end of in vitro differentiation approximately 5% of cells became insulin positive.
Mesenchymal stem cells (MSCs) can be derived from various sources. MSCs are undifferentiated cells with multilinear potential, known for their immunomodulatory and regenerative properties . The bone marrow, adipose tissue, umbilical cord, liver cells, and endometrium are among several tissues that are rich in MSCs. Of these, the bone marrow and adipose tissues offer distinct advantages in view of their availability and abundance and the extent of their documentation.
In this study the investigators aim to obtain autologous differentiated insulin producing mesenchymal stem cells (derived from adipose tissue) and their introduction in human subjects with type 1 diabetes. The current study will assess of the ability of the transplanted cells to produce insulin both in vitro and in vivo. Post- transplant glycemic control will be assessed with possible amelioration of the standard treatment of type 1 diabetes.
