1 From the 1920s to the 1980s, insulin from animals is used for treatment. 2  In the 1980s, the first generation of man-made insulin, called human insulin, is created. 3  This man-made insulin was genetically identical to the bodyâs naturally produced insulin. 4  By the late 1990s, man-made insulin analogs were being developed.nsulin helps move sugar from the blood into the bodyâs cells, where it can be used for energy. The pancreas releases insulin all the time. The pancreas is an organ that sits near the stomach. Special cells in the pancreas, called beta cells, make insulin.
