You have probably heard of stem cells in very different contexts. Seems like they are already used in cosmetic procedures, as well as in treating a variety of diseases. In future, even more, they may become a remedy for all. Or not? Well, here is a brief guide to the subject.
What’s the source of stem cells?
These cells are so-called undifferentiated cells that can be transformed into different cells of the body. For example, nerve cells or blood cells. They come in different forms: some are able to differentiate only into one type of cells, others have more abilities. Particularly, embryonic stem cells in the early pregnancy can transform into any type of body cells.
Potentially, we may grow new skin, or replace the liver tissue with them! Unfortunately, it is not yet possible to use stem cells for such purposes.
Still, we can obtain such kind of cells from embryos (for example, for research purposes, from abortive materials), from bone marrow in adults. In addition, they may be isolated from the pulp of the teeth, and from the umbilical cord of the newborn.
What are they used for?
Stem cells have been used for several decades in the treatment of severe blood and bone marrow diseases, such as leukemia.
The procedure of bone marrow transplantation is not similar to classical transplantation. In fact, it looks like a blood transfusion.
Do we need to store cells?
As with any potential remedy for all, or means of rejuvenation, a huge business has formed around these cells. There are more and more services for the storage just in case.
In fact, no one knows when these cells can be used in practice to treat a particular disease. Seems like for today, any private bank is just a way to spend a lot of money.
What’s the use of stem cells in cosmetics?
Stem cells are really added to cosmetics. But these are plant cells, usually from the apple tree. Such plant stem cells contain active substances that support the sensitivity of skin cells to hormones and neurotransmitters. Experiments show that compounds with plant stem cells make age changes in the skin reversible and slow the aging of the hair follicles.
