After years of research , viacyte developed a recipe capable of transforming embryonic stem cells into immature pancreatic cells , called progenitors .
In a paper published in 2008 , the company showed that transplanting the pancreatic progenitors into mice pushed these cells to fully differentiate inside the animal , enabling them to regulate blood sugar .
The t-cell precursors then go to the thymus , a small organ located under the breastbone , where they are called early thymic progenitors ( etps ) .
然后，t细胞的前体前往胸腺一个位于胸骨下的小器官，在那里，它们被叫做早期胸腺祖细胞（etps）。
The progenitors of the maastricht treaty -- led by france and italy , as well as smaller countries such as belgium and the netherlands , but including , too , most of germany 's leading politicians -- foresaw a variety of benefits .
