The vast majority of insulin used to treat diabetes is actually not produced in a lab. It is harvested from pigs, which share a surprisingly large about of DNA with humans.
Bacteria have a gene for producing human insulin added, and then they are grown and produce the insulin.
Insulin was until recently made by cultivating pancreas tissue from Cow, Pig and even Fish.
The insulin one got from these were slightly different from human insulin, but they do work as they intend to in humans.
It is and was considered time consuming and difficult to produce in sufficient purity and quantity and researchers started testing other methods.
Scientists have isolated the gene that starts the production of insulin. By inserting this gene in other organisms we can trick them into producing it for us.
The gene have been put into fungus and bacterias and it works very well.
In 2007 the scientists managed to put the gene into an actual plant. The plant grows well and produces large amounts of insulin. Something that makes this the most cost effective method of producing insulin today.
Scientist produce several different types of insulin these days. Humans have a sort of "slow" acting insulin and this is not always the best choice for a person with diabetes.
Fast absorbing insulin is often a better choice. It is not the same as human insulin but it does the job it is supposed to do.
I will at the end just point out that:
The insulin itself is not genetically engineered.
We have genetically engineered plants and bacteria and fungus to produce the insulin for us.
Best successfully purified insulin, from a dog's pancreas. In 1936, researchers came up with a way, to make insulin with a slower release in the blood. They added a protein found in fish sperm, protactinium, which the body is able to break down slowly. One injection lasted for 36 hours. In the 1970s, researchers began to try and produce an insulin that had more resemblance to the body's natural insulin.

Is the insulin made by E.coli better or worse than insulin made by human?
The insulin that we engineer bacteria to make (E.colidoes not naturally make insulin) is identical to human insulin.
Is there pig pee in the insulin?
No . . . human insulin is made from pig insulin, quite often.
Can insulin be made from cat urine?
No. Insulin is a specific hormone made by beta cells in the pancreas.
Where are the insulin and glucagon made?
Insulin is made by beta cells of pancrease.Glucogon is made by alpha cells of pancrease.
Is cow or pig insulin made from their urine?
No it is made by their pancreas. Artifical insulin is made by recombinant DNA gene technology.
How is serum insulin made?
Insulin is made by the islet cells in the pancreas. These are the endocrine cells found in the pancreas.
Can NPH and Regular insulin be mixed?
yes...because regular insulin and Isophane Insulin(NPH) is a human-made form of insulin. Insulin is a hormone produced naturally by pancreas
Is insulin lipid?
No it is not a lipid. Insulin is made up of proteins. It cannot be injected orally.
What is the mixture made by the pancreas?
Insulin
What is the hormone made by the pancreas?
Insulin
Differentiate between keratin and insulin?
There are similarities in Keratin and Insulin, they are used differently. Insulin and Keratin are both made inside the human body and they are also both made synthetically. Insulin stays in liquid form while Keratin is a hardened form which an be has hard as finger nails or as soft as hair. Insulin in made synthetically and used for medical purposes where Keratin is made synthetically and used for beauty purposes.
Why insulin is used?
Insulin is usually made in your body automatically; diabetes is when your body does not make enough insulin. So some people with diabetes have to take insulin to control their blood sugar.
