Every day seems to bring new breakthroughs in medical technology that are sometimes difficult to understand. Much of it can seem exciting, although many are concerned about the religious and moral implications that they bring with them. The value of stem cell research facilities, and what exactly they do, can be more readily understood once it's broken down.
Understanding what stem cells are is the first step. In the simplest terms, these cells are the tree trunks that sprout branches that have special functions. Researchers have learned how to divide the trunks into two different branches. These are daughter cells that can grow into other trunks, self-renewing, or create entirely new branches, with differentiation, that have specialized functions. These might be bone, blood, heart muscle, or brain cells. These trunks, or stems, are the only cells in the human body that are capable of naturally generating new kinds of cells.
When researchers watch these cells grow, they start to learn the ways in which diseases develop. Regenerative medicine is the art of regenerating and replacing human cells to the place where normal function is restored. Stems have the ability to create special cells that regenerate or repair damaged or diseased tissue located anywhere in the human body.
There are any number of diseases, that don't currently have cures, that might be eradicated. These include type 1 diabetes, cancer, spinal cord injuries, Alzheimer's disease, Parkinson's disease, and strokes, among many others. Transplants have the potential of becoming viable with the use of new tissue that is grown from stems. Researchers are working on applications that may be useful for regenerative and transplant medicine.
Researchers can use the stems to test new drugs. Instead of using humans as guinea pigs, researchers can these cells to study how safe they are for human use and how well they work. Cardiac toxicity tests are showing great promise.
Researchers are studying how well stems, that are programmed to turn into cells specific to tissue, might be for new drug testing. To get the utmost accuracy, the cells must be programmed to mimic the types of cells the new drugs are targeting. For example, tests made on blood cells might show what kind of effect new drugs will have on them.
Scientists can draw stems from a variety of sources, one of which is particularly problematic for some groups. Embryonic cells are taken from embryos that are only a few days old. These cells are unique because they can divide into more stem cells, or any other kind of cell that is in the human body. Embryonic cells have been the focus of those raising ethical objections to this type of research.
Embryonic cells can be mimicked with the use of adult stems. Genetic reprogramming has been used in order to alter genes in adult cells. This new technique may prevent resistance from the new cells when it comes to immunity. Whether it adversely affects the human body is still under investigation.
