Genetic Engineering New Teeth :: Genetic Engineering Essays

The phrase I contemplate was about some scientists that were able to grow teeth inside rats bodies. This go out was led by Pamela C. Yelick, a scientist for Forsyth Institute, and the project was conducted in Massach enforcetts. Joseph P. Vacanti, a tissue paper engineer at Massachusetts General Hospital, and Yelick had the idea for the experiment.Vacanti had previously worked with rats and he found that cells will naturally organize themselves into tissues and other complex structures if they atomic number 18 placed in the right environment. Vacanti and Yelick hypothesized that the same approach could be utilise to growing teeth. Previous research had identified the stem cells that make dentin, moreover no one had been able to use the stem cells that make tooth beautify prior to this experiment.The teeth were formed inside the bellies of rats using stem cells from pigs. Yelick obtained the cells from cast away pig jaws at a meat packing plant. The scientists removed a mol ar that had not yet erupted from the pig jaw to use for the project. They farming the molar into small pieces and treated it with enzymes to break it down into small patches of cells.The cells were and so placed into a scaffold and implanted into the rats. The scientists placed the scaffolds in the blood-rich tissue near the rats intestines. This area provided the nutrients that the cells needed to grow. The rats used in the experiment had diminished immune systems that would not reject the foreign tissue.At that point, the researchers could only attend for the teeth to grow. As an added precaution, the rats were placed in a special white room behind locked doors. The researchers would periodically x-ray the rats to see if anything had grown, but it was not until after several months that they actually found encouraging splotches inside the rats.This name showed that we can use stem cells to create tooth enamel that we can use for new teeth and other dental needs in the future . earlier this project, the idea of creating teeth using stem cells was only a thought. In class we talked about the creation of human organs inside of animals, copy animals, and cloning humans, but we had not mentioned cloning teeth. Cloning humans brought up many ethical issues, but I do not speak out cloning teeth would pose any problems. The information in this article seems biased. The Boston Globe is definitely not a scientific journal.
