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. The research will help you know more about stem cells. The main categories of stem cells are two. 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. Embryonic stem cells are the stem cells that are derived from human embryos.
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. 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. All cells making the embryo are stem cells within the first four to five days after fertilization. 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.
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 multiplied in a laboratory and not grown in a woman’s womb. 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.
