Stems Cells Explored
The medical field has experienced numerous advancements over the years. The numerous advancements are due to 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. The differences between stem cells and regular cells are numerous. You need to research more about stem cells if you want to understand stem cells more. Stem cells are mainly of two types. The two types of stem cells are adult stem cells and embryonic stem cells. The name used to refer to stem cells derived from living human beings is adult stem cells. Stem cells that are derived from human embryos are referred to as embryonic stem cells.
Adult stem cells cannot become all the cell types found in the human body, but they are as versatile as embryonic stem cells. 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 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.
All the stem cells found in the human body can be developed from induced pluripotent stem cells, just like in embryonic stem cells. Adult stem cells are easy to harvest, available in plenty, and have a low risk of immune system injection in patients even though they cannot divide to create every type of cell found in the human body. 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 pluripotency of the stem cells forming the embryo ends five or six days after fertilization.
Perinatal stem cells are mostly sourced from amniotic fluid and tissue, umbilical cord blood and tissue, and placental blood and tissue. Adult stem cells are mainly harvested in three ways; bone marrow extraction, blood draw, and tissue fat extraction, also 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. 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.
