Effect of alloxan on permeability of pancreatic islet tissue in vitro.
After implantation, these cells are expected to become mature human islet tissue including well-regulated beta cells producing insulin on demand.
Morphometric analysis showed that the number of islets/mm2 decreased (p=0.001) in alloxan-induced damage to the islet tissue and the difference was statistically significant when group C2 was compared with control groups (p0.05).
Following the first macrobead implantation, all animals remained insulin-free for a period of nine days despite the implantation of a suboptimal critical mass of islet tissue (Figure 1).
The Islet tissue comprises 1-2% mass of healthy adult human pancreas; there are about one million islets collectively weighing 1-2 g (Langerhans, 1869).
