collagen-collpant.jpg In what can be termed as a breakthrough, an Israeli company CollPlant Ltd has come out with a transgenic tobacco plant that produces human collagen. The plant co-expresses the 5-human proteins which results in assembly of triple helical collagen molecules. Depletion of collagen production due to aging is the prime cause of wrinkles or ageing signs of skin, in humans. However the findings have to pass further tests, before it is used for the set purpose.
