The biological cells that are undifferentiated and can differentiate into more particular cells and can divide themselves through a process of mitosis to produce more similar cells are known as Stem cells. Stem cells are found in multi cellular things and organisms. Two main types of stem cells are found in mammals: Adult Stem cells which are obtained in various tissues and embryonic stem cells, which are separated from the inner cell mass.
Generally, stem cells possess two properties:
- Self-renewal: While maintaining the undifferentiated state, the capacity to go through numerous cycles of cell division.
- Potency: the ability to differentiate into particular cell types. It gives rise to mature cell type. Also, feed-back mechanism regulates stem cell function.
Jeunesse is an international skin care company that carries a number of cleansing and anti aging products for the skin, together with a number of nutritional products such as dietary and supplements aids. Jeunesse claims to use DNA science and cutting-edge stem cell in their product line with a focus on repairing dented skin.
How can stem cells be obtained?
In the laboratory, cell cultures are grown by transferring about 30 inner cell mass of about 30 cells into a culture dish containing a nutrient broth. The cells quickly multiply in number and fill the dish. They are then transferred to other cell culture dishes and the process continues for months. Once the cells are produced they can be chilled and shifted to other laboratories.
Are there any potential stem cell sources?
Adult stem cells can be used to reproduce similar cells and are a potential source. Adult stem cells can only reproduce similar cells unlike embryonic stem cells which can differentiate into any kind of cell of their type. However, with the advancement of new and modern science it has been proved that some of the adult stem cells may be able to differentiate into other cell kinds.
In vitro, properties of stem cells can be illustrated using procedures such as clonogenic assay, where single cells are examined for their ability to self-renew and differentiate. Stem cells can also be separated by their possession of a particular set of cell markers. Vitro culture situations can change the nature and behaviour of cells, making it ambiguous whether the cells will behave in the same manner in vivo. There are many controversies and debates as to whether some adult cell populations are truly stem cells.
Jeunesse is intimately aligned with the future of Dr. Nathan Newman, a global-renowned dermatologist. Hailing from Beverly Hills where he is well-known for his stem cell face lifts, Dr. Newman is knowledgeable in using adult stem cells to invalidate signs of aging. In his preparation, he produces the stem cells from a patient’s fat cells and injects them into the target parts on the face. For Jeunesse Global, he is using his proficiency to devise an at-home topical treatment to attain the same effect as his in-office cosmetic procedures. The topical healing uses stem cells, too, but can be used at house. The product is known as “Luminesce”.
