Information about Stem Cells
The medical field has experienced numerous advancements over the years. The reason for the numerous advancements in the technologies that have been invented. Stem cell therapy has been deemed to have great promise in treating various diseases medical conditions due to the numerous advancements made in the medical field. The differences between stem cells and regular cells are numerous. If you want to understand stem cells more, you need to research more about stem cells. The main categories of stem cells are two. Stem cells are mainly categorized into 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. Stem cells were first used for the umbilical cord, and bone mallow transplantation. However, some scientists believed that the inability of adult stem cells to become all the cell types found in the human body made them inferior to embryonic stem cells. Scientists hope by reprogramming adult stem cells, they can make them capable of becoming any cell type in the human body. Induced pluripotent stem cells is the other name for reprogrammed adult stem cells.
Like embryonic stem cells, induced pluripotent stem cells can become all the stem cells found in the human body. 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. The embryo is mainly made up of only stem cells within the first four to five days after fertilization. The stem cells in embryos are responsible for developing into any type of cell in the human body. The stem cells forming the embryo cease to be pluripotent 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. The main ways of harvesting adult stem cells are bone marrow extraction, blood draw, and tissue fat extraction, referred to as liposuction. Embryos used to harvest embryonic stem cells are not grown in a woman’s womb; instead, they are multiplied in a laboratory. About ten percent of a donor’s bone marrow is extracted; hence if you want to be a stem cell donor, you should be prepared to feel fatigued and sore for a few weeks. A sem cell done is sedated when the procedure of extracting stem cell cells from his or her bone marrow can be painless.
