how many kinds of stem cells are there?
6716
There are three types of stem cells: adult stem cells, embryonic (or pluripotent) stem cells, and induced pluripotent stem cells (iPSCs).

In humans alone we have a huge range of different cell types, all of which are eukaryotic. For example, we have red blood cells, white blood cells, skin cells, muscle cells, fat cells or adipocytes, and bone cells.

Bone marrow also contains multipotent stem cells that give rise to all blood cell types but not other cells. ... This particular stem cell has been found to give rise to bone, muscle, cartilage, fat, and other similar tissues. Multipotent stem cells are essentially committed to produce specific cell types.

Terms in this set (5) Stem cells have the potential to become any type of cell once they are further along in development. Differentiated cells, on the other hand, already have a set purpose and can only become one type of cell when they develop and mature.

What's the difference between a stem cell and a normal cell? The difference is that the normal cell can only ever replicate itself (if it can even replicate). Stem cells, depending on where they are in the hierarchy, can produce from multiple different cells in a tissue type to the entire human body.

The blood-forming stem cells in red bone marrow can multiply and mature into three significant types of blood cells, each with their own job: Red blood cells (erythrocytes) transport oxygen around the body. White blood cells (leukocytes) help fight infection and disease.

They begin their life as stem cells, and they mature into three main types of cells— RBCs, WBCs, and platelets. In turn, there are three types of WBC—lymphocytes, monocytes, and granulocytes—and three main types of granulocytes (neutrophils, eosinophils, and basophils). See them in action in "Meet the blood cells".

Amniotic stem cells. Amniotic stem cells are the mixture of stem cells that can be obtained from the amniotic fluid as well as the amniotic membrane. They can develop into various tissue types including skin, cartilage, cardiac tissue, nerves, muscle, and bone.

A living thing can be composed of either one cell or many cells. There are two broad categories of cells: prokaryotic and eukaryotic cells.

These include embryonic stem cells that exist only at the earliest stages of development and various types of tissue-specific (or adult) stem cells that appear during fetal development and remain in our bodies throughout life. ... Tissue-specific stem cells. Mesenchymal stem cells. Induced pluripotent stem cells.

Placental stem cells are not totipotent, because only two types of stem cells have this capacity: embryonic stem cells, and a reprogrammed type of stem cell, known as an induced pluripotent stem cell (iPS cell).

Pluripotent adult stem cells are rare and generally small in number, but they can be found in umbilical cord blood and other tissues. Bone marrow is a rich source of adult stem cells, which have been used in treating several conditions including liver cirrhosis, chronic limb ischemia and endstage heart failure.
433103
Pluripotent cells are capable of forming virtually all of the possible tissue types found in human beings. ... Multipotent cells produce only cells of a closely related family of cells (e.g., hematopoietic stem cells differentiate into red blood cells, white blood cells, platelets).

Stem cells in medicine Every type of blood cell in the bone marrow starts as a stem cell. Stem cells are immature cells that are able to make other blood cells that mature and function as needed. These cells are used in procedures such as bone marrow transplants.

From Wikipedia, the free encyclopedia. Amniotic stem cells are the mixture of stem cells that can be obtained from the amniotic fluid as well as the amniotic membrane. They can develop into various tissue types including skin, cartilage, cardiac tissue, nerves, muscle, and bone.
