Information about Stem Cells
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. 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. 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. The main categories of stem cells are two. Adult stem cells and embryonic stem cells are the two types of stem cells. Stem cells derived from living human beings are referred to as adult stem cells. The name used to refer to stem cells derived from human embryos is 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, some scientists believed that adult stem cells are inferior to embryonic stem cells because adult stem cells cannot become all the cell types found in the human body. Scientists hope they can make adult stem cells capable of becoming any cell type in the human body by reprogramming adult stem cells. The other name for reprogrammed adult stem cells is induced pluripotent stem cells.
Induced pluripotent stem cells can become all the stem cells found in the human body, the same as 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. The stem cells in embryos are responsible for developing into any type of cell in the human body. Five or six days after fertilization, the stem cells forming the embryo cease to be pluripotent.
Perinatal stem cells are mostly sourced from amniotic fluid and tissue, umbilical cord blood and tissue, and placental blood and tissue. 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. You should be prepared to feel fatigued and sore for a few weeks if you want to be a donor for stem cells 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.
