Diabetes researchers are considering various replacements for insulin injections: Transplanting new pancreatic
islet cells that
make insulin, coaxing the patient's own
islets to regenerate, or treating diabetics early in the disease with immune - suppressing therapies to prevent their body from destroying the rest of their pancreatic
islets.
Using the material and protein combination, the researchers evaluated multiple locations for implanting the
islet cell clusters, the first time such a direct comparison of transplant sites has been
made.
The investigators demonstrated robust new growth of
islets and their saliva -
making equivalents, and by a painstaking procedure, they proved Faustman's final proposition — that spleen
cells had converted to both
islets and salivary tissue.?
«The loss of insulin - producing beta
cells leads to type 1 diabetes,
making it an ideal target for
cell replacement therapy,» said James Shapiro, MD, PhD, FRCSC, Director of the Clinical
Islet Transplant Program, University of Alberta.
Once implanted, the
cells are designed to differentiate into the various
cell types that
make up the pancreatic
islet, which could allow for production of insulin and other hormones, such as glucagon, needed to control blood sugar levels.
The pluripotent stem
cell process could allow researchers to
make genetic changes to dampen or potentially eliminate the rejection of the pig
islets by the human immune system.
Unfortunately, conventional sorting techniques have not been sufficient to isolate the individual
islet cell types,
making it impossible to analyze each one's gene expression program and its potential contribution to dysfunction.
Neuroendocrine pancreas
cells (such as
islet cells)
make several hormones, including insulin and glucagon, that help control sugar levels in the blood.
Based on animal experimentation, PEC - 01 progenitor
cells have the capacity to both self - renew;
making more
cells, and differentiate into mature, functional pancreatic
islet cells.
The immune system attacks and damages the
islet cells that
make insulin in the pancreas.
Insulin is a hormone
made in the beta
cells in the
islets of Langerhansin the pancreas.
It is critical to monitor insulin needs very closely if an attempt is
made to correct high blood sugar using insulin in a dog with acute pancreatitis, in order to avoid the risk of shock due to an over dosage of insulin when the
islet cell function returns and the pancreas begins to
make insulin normally.
