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. 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. The main categories of stem cells are two. Adult stem cells and embryonic stem cells are the two types of stem cells. Adult stem cells are the stem cells derived from living human beings. 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 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. 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 dividing to create every type of cell found in the human body is not within the capacity of adult stem cells, they available in plenty and have a low risk of immune system injection in patients. 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 stem cells forming the embryo cease to be pluripotent 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. Bone marrow extraction, blood draw, and tissue fat extraction, also referred to as liposuction, are the main ways of harvesting adult stem cells. A woman’s womb is not used as a growing and multiplication environment of embryo cells; instead, embryo cells are multiplied in a laboratory If you want to be a donor for stem cells, you should be prepared to feel fatigued and sore for a few weeks 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.
