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 can be gathered from various sources, including bone marrow, umbilical cord blood, and peripheral blood. They can also be generated through reprogramming adult cells, known as induced pluripotent stem cells. Some tissues in the body also contain stem cells that can be harvested for research or therapeutic purposes.

∙ 12y agoStem 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).

What are the types of stem cells?
There are two main types of stem cells: embryonic stem cells, which are derived from embryos, and adult stem cells, which are found in adult tissues and can differentiate into a limited range of cell types. Additionally, induced pluripotent stem cells (iPSCs) are adult cells reprogrammed to behave like embryonic stem cells.
What type of cells have the ability to divide and produce new cells throughout their lifetime?
Pluripotent stem cells.
What are the three types of stem cells in adults?
The three types of stem cells in adults are hematopoietic stem cells (found in bone marrow and produce blood cells), mesenchymal stem cells (found in various tissues like bone marrow and fat, can differentiate into bone, cartilage, and fat cells), and neural stem cells (found in the brain and spinal cord, can differentiate into neurons and supporting cells).
What type of cell are stem stem cell described as?
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.
What are the three main types of stem cells?
The three main types of stem cells are embryonic stem cells, adult stem cells, and induced pluripotent stem cells. Embryonic stem cells are derived from embryos, adult stem cells are found in various tissues of the body, and induced pluripotent stem cells are reprogrammed adult cells with properties similar to embryonic stem cells.
What are the types of stem cells?
There are two main types of stem cells: embryonic stem cells, which are derived from embryos, and adult stem cells, which are found in adult tissues and can differentiate into a limited range of cell types. Additionally, induced pluripotent stem cells (iPSCs) are adult cells reprogrammed to behave like embryonic stem cells.
What replaces dead or damaged cells?
Dead or damaged cells are replaced by nearby healthy cells that divide and multiply to fill in the empty space. In some cases, stem cells can also differentiate into the specific cell type needed to replace the damaged cells.
What are the three types of stem cells in adults?
The three types of stem cells in adults are hematopoietic stem cells (found in bone marrow and produce blood cells), mesenchymal stem cells (found in various tissues like bone marrow and fat, can differentiate into bone, cartilage, and fat cells), and neural stem cells (found in the brain and spinal cord, can differentiate into neurons and supporting cells).
What are unspecialized human cells called?
Unspecialized human cells are typically referred to as stem cells. These cells have the potential to develop into different types of cells in the body.
How many different types of tissue stem cells are there?
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.
What kind of stem cells can only develope into cells that are closely related to the original stem cells?
Multipotent stem cells
What kind of stem cells can only develop into cells that are closely related to the original stem cells?
Multipotent stem cells
What kind of stem cells can develop from unipotent stem cells?
What kind(s) of cells can develop from unipotent stem cells
What type of cells have the ability to divide and produce new cells throughout their lifetime?
Pluripotent stem cells.
Cells that retain the ability to divide continuously without specializing are called?
Cells that retain the ability to divide continuously without specializing are called stem cells.
Are stem cells human?
Yes, some stem cells do come from humans. The stem cells are taken from embryos. Animals also have stem cells used in research.
Why do researchers prefer to use embryonic stem cell stem cells instead of adult stem cells?
embryonic stem cells can differentiate into more types of cells
