I was reading about how stem cells are used so much in research in recent years to grow and develop organs in the lab. In particular, the advancements being made in growing mini brains. How amazing would it be if we were one day able to develop a fully functioning brain from our own brain cells that could be transplanted into brain dead patients!<\/p>\n\n\n\n
Many ongoing experiments have been able to take human tissue and develop it into cerebral organoids, better known as mini brains. But what is the science behind this? I read an article written by Tiare Dunlap from University of California, Los Angeles. The article explains that scientists take the human tissue and engineer it to become induced pluripotent cells. Induced pluripotent cells are cells that can differentiate into any cell type in the body. They can then take these cells and by changing the environment the cells are in they can make them become neural stem cells. These neural stem cells are capable of developing into most of the types of cells found within the brain. The article also explained how there is no set protocol that is used across labs resulting in huge differences between ongoing experiments. I suppose the differences obtained in the results of the experiments can be a good thing in such a new and developing area of science. However, it did make me question if discoveries could ever be backed up with more evidence if each experiment carried out is slightly different. Is it limiting the discoveries that could be made within this highly important research?

I found this video which gives a good summary of the the ongoing research and some of the science behind it.<\/p>\n\n\n\n
