I’m not familiar with this website but I have heard of nearly all of the trials/companies they discuss.
I found the article very interesting discussing each companies method of curing and where they are in the process.
Quick Summary assuming the article is accurate.
Several companies are using different forms of stem cell’s to replace lost beta cells. Most of them are working on proving the safety of their method to start clinical trials. One or two have already started phase 1 trials.
