Moving closer to producing heparin in the lab. Researchers moved one step closer to the ability to make heparin in cultured cells. Heparin is a potent anti-coagulant and the most prescribed drug in hospitals, yet cell-culture-based production of heparin is currently not possible. Heparin is now produced by extracting the drug from pig intestines, which is a concern for safety, sustainability, and security reasons. Source 9k.
Pig intestines? I don't think anyone who's going to take in that sort of drug would like to hear it's origins at all. I would like to know how they'd deal with the health aspects since you know; there can be parasites that sometimes goes undetected or what not during the creation process. I know some might think that might sound crazy but with anything regarding animal products there's always some sort of hidden, deep risk.
