  • The pancreas is not really stable enough to be implanted in at all. Other organs you’re imagining like liver, stomach, heart, etc. have a solid lining that can be cut open and stitched back together. The pancreas is more like a cluster of loose cells with veins throughout and held together by a very thin, tissue paper lining. If you try to open it and insert cells, you’re not going to be able to put it back together.

    That’s why cells are usually put in the liver, which has a large vein going directly to the pancreas. Close proximity and high blood supply. Implanting in the pancreas will likely never be an option unless you can drastically reduce the volume of cells.

    Our lab was working on implanting the stem cells on a porous scaffold in the fat pad of the stomach as an alternative


  • Unfortunately, that doesn’t necessarily negate the requirement for immunosuppresors or some other kind of immuno protection. If it is Type 1 diabetes, the person originally became diabetic because the immune system saw certain markers on the beta cells (insulin producing cells) as a threat. So, if you recreate the beta cells, there is still a possibility that it will happen again. You are fighting your own immune system. Someone in our lab was studying encapsulation of cells to create a protective barrier around them for this very issue

    If the person was Type 2, this might be less of a risk since type 2 can also be due to high insulin resistivity. There are a lot of other factors involved, though, it’s not straightforward
