To enable ES (embryonic stem) cells to grow outside of the embryo they have to be cultured in the presence of embryonic fibroblasts, which provide nutrients to keep
the ES cells in an undifferentiated state. In this state the cells can
grow indefinately. When these cells are removed from the fibroblasts (or
medium which has been conditioned by these cells) the ES cells
spontaneously differentiate into a range of cell types. In theory, ES
cells can form into any of the cells within the body. However, in practice
only a few pure cell types have been produced (e.g. neuronal and blood).
Stem cells are biological cells popularly known for its self-renewal abilities. There are two broad types of stem cells and each has its own harvesting procedures. First is the embryonic stem cell which can only be harvested by destroying a fertilized human embryo. This procedure is considered illegal and must be stopped. The other type of stem cell is adult stem cells. These cells are found in the various tissues of the human body (bone marrow, mammary gland, blood, umbilical cord, hair follicles, human testicles).
Stem cells are gathered from a 4 to 5 day Embyro of a human.
Stem cells can be found in umbilical cord of a delivered baby.
Stem cells can be collected from human embryos, blood, or bone marrow.
There are five basic stem cells classifications there is embryonic stem cells, fetal stem cells. There are the Umbilical cord stem cells, placenta stem cells, and lastly there are adult stem cells.
There are 2 type of stem cells * embryonic stem cells * and adult stem cells fetal stem cells are grouped into the adult stem cell category
Three types of stem cells in adults are hematopoietic stem cells, mesenchymal stem cells, and neural stem cells.
Pluripotent stem cells.
Stem cells are considered as undifferentiated cells. They will divide and divide forming more stem cells. The two main stem cell types are embryonic stem cells and adult stem cells. Only the embryonic stem cells can become any type of tissue. Embryonic stem cells have the potential to become any type of cell in the body. There is news as of 2015 that perhaps blindness can be cured using these embryonic stem cells.

stem cells
Three types of stem cells in adults are hematopoietic stem cells, mesenchymal stem cells, and neural stem cells.
They are called stem cells.
Stem cells are cells that are able to divide continuously without specializing. These kind of cells are undifferentiated biological cells.
There are three different types of tissue stem cells in the body. They include the tissue stem cells also known as adult stem cells, embryonic stem cells, and induced pluripotent stem cells.
Multipotent stem cells
Multipotent stem cells
What kind(s) of cells can develop from unipotent stem cells
Pluripotent stem cells.
Yes, some stem cells do come from humans. The stem cells are taken from embryos. Animals also have stem cells used in research.
