As many of us know Stem Cells have been a very controversial but interesting topic for the past few decades. Stem cells have been shown to be able to do a multitude of amazing things in the human body. The problem with these stem cells, at least the embryonic version, is one of the only ways to get them is from the amniotic fluid of a newly growing baby. Another type of stem cell is found in some adult tissues such as bone marrow but has much less ability to give rise to other kinds of cells.
Recent advances in stem cell technology have given rise to induced-pluripotent stem cells by genetic reprogramming. Scientists can take a regular adult cell and by reprogramming the cell can be able to inject this and other cells in to the affected area to heal the problem. So far this has seen promise but scientists are not sure if any adverse effects will be seen in adult humans.
The most recent breakthrough was seen about a month ago when scientists found that if you subjected a cell to physical stress then the cell would regress back into a regular stem cell. Putting regular blood cells into an acid bath for a certain amount of time would eventually turn these blood cells back into stem cells. This would be a huge breakthrough in the world of stem cell science. This would take away the controversy of using embryonic cells and the donors for these cells could come straight from the patients themselves!
This would be a huge breakthrough for the world of stem cells but in even more recent news the scientists that have been trying to prove this idea and replicate the results have been having a extremely hard time. This has brought the plausibility and the reliability of these results into question. It looks as though this time we will have to wait a little longer for an end all, be all in finding perfect stem cell therapy.
