Stem cells are a type of cell that have the extraordinary ability to transform into any specialized cell in an organism. These cells are able to differentiate, through cell divisions even if stored for long periods of time. In summary, a stem cell is able to pass through several cell divisions creating a large number of cells, capable of forming tissues, restoring organs, among many other benefits.
The great controversy surrounding these cells is that they need to be extracted from embryos. As you know, the embryo is the initial stage of a living organism and for that reason, many people believe that it is unethical to remove cells from an embryo when it does not have the capacity to allow or deny it. Other people claim that the regenerative power of stem cells should not be manipulated by humans, as it takes away the sovereignty of God in relation to life and the human body. There are also people who believe that the regeneration capacity of these cells is somewhat controversial and that the negative points of using them have not been fully explained.
However, we must see scientific research that uses stem cells as a major scientific advance, which will help countless people around the planet, such as people with osteoporosis, bone problems, cancers, among others. Such research should be encouraged, so that the problems surrounding stem cells are resolved and this technology can be used.
