Embryonic Stem Cell Processing in Obtaining Insulin-Producing Cells: A Technical Review
2006
Diabetes mellitus derives from the absence of insulin hormone in the organism, usually due to the destruction of insulin-producing pancreatic β-cells either by immune attack or glucolipotoxic mechanisms. Insulin is a key hormone in controlling nutrient (glucose and fatty acids) homeostasis, as well as modulating both their uptake and metabolism by peripheral target tissues, such as skeletal muscle and adipose tissue. Insulin injection can partially mimic endogenous hormone function, although it does not avoid the appearance of secondary complications such as retinopathy, nephropathy, neuropathy, and cardiovascular disorders. Implantation of de novo insulin-producing cells in the organism could be a long-term solution in the treatment of the disease, restoring the lost function. Transplantation of highly pure isolated islets (pancreatic cell clusters where β-cells are located) from cadaveric donors is a possibility, although there are still many problems to resolve, such as immune rejection, low isolation ...
