Which bacteria is used in the production of insulin by genetic engineering

---

Fifty years ago, a great achievement in life science occurred in China—the complete synthesis of crystalline bovine insulin—which gave Chinese scientists a sense of great elation and pride.

Insulin (Fig. 1) is a hormone secreted by β cells in pancreas. Before the clinical application of insulin, diabetes was a feared disease that commonly led to death.

Insulin has been studied since 1868 when Paul Langerhans, a medical student in Berlin found clusters of cells in the pancreas (Langerhans, 1868). These were later called ‘‘Islets of Langerhans’’. Some of these cells were eventually shown to produce insulin.

The term ‘‘insulin’’ origins from ‘‘Insel’’, the German word for “islet” or “small island” (Sakula, 1988).
