Stems Cells; All You Need to Know about Them
Over the years, the medical field has experienced a lot of advancements. The reason for the numerous advancements in the technologies that have been invented. Due to the numerous advancements made in the medical field, stem cell therapy has been deemed to have great promises in treating various diseases, and medical conditions. Stem cells vary a lot of difference from regular cells. You need to research more about stem cells if you want to understand stem cells more. There are two main types of stem cells. The two types of stem cells are adult stem cells and embryonic stem cells. Adult stem cells are the stem cells derived from living human beings. Stem cells that are derived from human embryos are referred to as embryonic stem cells.
Adult stem cells are as versatile as embryonic stem cells, but they cannot become all the cell types found in the human body. The first uses of stem cells were umbilical cord and bone mallow transplantation. However, the inability of adult stem cells to become all the cell types found in the human body made some scientists believe that adult stem cells are inferior to embryonic stem cells. Scientists hope they can make adult stem cells capable of becoming any cell type in the human body by reprogramming adult stem cells. Reprogrammed adult stem cells are also referred to as induced pluripotent stem cells.
All the stem cells found in the human body can be developed from induced pluripotent stem cells, just like in embryonic stem cells. Even though adult stem cells cannot divide to create every type of cell found in the human body, they are easy to harvest, available in plenty, and have a low risk of immune system injection in patients. Within the first four to five days after fertilization, all cells making the embryo are stem cells. Different types of cells form from the stem cells in the embryo. The pluripotency of the stem cells forming the embryo ends five or six days after fertilization.
Amniotic fluid and tissue, umbilical cord blood and tissue, and placental blood and tissue are the most common sources of perinatal stem cells. Bone marrow extraction, blood draw, and tissue fat extraction, also referred to as liposuction, are the main ways of harvesting adult stem cells. Embryos used to harvest embryonic stem cells are not grown in a woman’s womb; instead, they are multiplied in a laboratory. If you want to be a donor for stem cells, you should be prepared to feel fatigued and sore for a few weeks because about ten percent of a donor’s bone marrow is extracted. So that the procedure of extracting stem cells from the bone marrow can be painless the donor sedated.
