Studies focusing on the immune mechanism of T/B cell destruction in T1DM have made breakthroughs. These results suggest that allogeneic bone marrow transplantation (ABMT) might prevent islet destruction, and help to restore self-tolerance (Ikehara et al., 1985). Many studies have highlighted the importance of reciprocal coordination and complementary interactions of different types of islet cells for glucose hemostasis [51,52,53,54]. This study provides a new framework for understanding islet embryogenesis and offers novel ideas to optimize the current protocols for the differentiation of SC- cells. doi: 10.1038/nbt1393, Lehuen, A., Diana, J., Zaccone, P., and Cooke, A. 2015;2015:762098.

The insulin gene can be isolated, cloned and prepared as plasmid which can be introduced into a variety of cells, but the process is not straightforward to enable anything approaching the kind of genetic engineering that would be necessary to treat a diabetic patient. By adding diverse cytokines (e.g., epidermal growth factor, bFGF) and signaling modulators (e.g., bone morphogenetic proteins, -secretase inhibitors) to each stage to activate or inhibit specific signaling pathways (e.g., Notch, Wnt) involved in the generation of adult cells, the hPSC cell fate is manipulated into the cell phenotype [18, 20, 23]. Navarro-Tableros V, et al. Hence, hPSCs provide a promising platform to produce in vitro insulin-secreting cells. Google Scholar. Farney AC, Sutherland DE, Opara EC. set up the first stepwise protocol to produce endocrine hormone-expressing cells that were able to synthesize and release multiple hormones from hESCs. Stem cells for the treatment of diabetes are able to come from a variety of sources. (2010). Islet-like structures generated in vitro from adult human liver stem cells revert hyperglycemia in diabetic SCID mice.
