Stems Cells Explored
The medical field has experienced numerous advancements over the years. The technologies that have been invented are the reason behind the numerous advancements. Various diseases and medical conditions that were impossible to treat or correct can now be treated or reversed with stem cell therapy. Stem cells have numerous differences from the 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. Stem cells that are derived from human embryos are referred to as embryonic stem cells.
Even though adult stem cells cannot become all the cell types found in the human body, they are still as versatile as embryonic stem cells. Umbilical cord and bone mallow transplantation were the first uses of stem cells. 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. All cells making the embryo are stem cells within the first four to five days after fertilization. Every cell in the human body was a stem cell during the first four to five days after the embryo was fertilized. 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. 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. 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. When stem cells are being extracted from a donor’s bone marrow, the donor sedated so that the procedure can be painless.
