What Part of the Human Body Contains Stem Cells?

0

Stem cells are unlike other cells in the body because they can replenish other cells as they deteriorate. They replicate frequently and can become other types of cells, such as muscle or brain cells. Two types of human stem cells exist: embryonic and adult. Embryonic Stem Cells Embryonic stem cells come from human blastocysts, which are newly fertilized eggs. The embryos used in stem cell research generally are conceived through in vitro fertilization and donated for research. They are then cultured in a laboratory. Umbilical Cord Stem Cells Scientists have discovered the blood within the umbilical cord is rich in stem cells. Some parents of newborns opt to harvest and store the blood from their baby’s umbilical cord for possible future transplants. Adult Stem Cells Adult stem cells are located within the brain, blood and blood vessels, bone marrow, skeletal muscle, heart, liver, intestines, ovaries, testes, skin and teeth. Scientists believe within each organ or tissue location, the s

Adult Stem Cells Adult stem cells are located within the brain, blood and blood vessels, bone marrow, skeletal muscle, heart, liver, intestines, ovaries, testes, skin and teeth. Scientists believe within each organ or tissue location, the stem cells reside in a specific place called a “stem cell niche.” Types As stem cells divide, they can become other types of cells. Hematopoietic stem cells become varying types of blood cells, including red blood cells, T-cells and macrophages. Mesenchymal s
