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.

What is the major difference between embryonic stem cells and somatic stem cells?

How does cord stem cells helps people?

Cord stem cells are exactly like normal stem cells, but they do come from an aborted fetus like most stem cells. Just like normal stem cells, they can be used to create any other cell needed in the human body.

Where do lymphocytes come from?

Lymphocytes are white blood cells. They are produced in the red bone marrow of our bones. The red bone marrow is derived from mesenchymal cells known as pluripotent stem cells. To produce blood cells, the pluripotent stem cells generate myeloid stem cells and lymphoid stem cells. The lymphoid stem cells then become lymphoblasts and then lymphocytes.

Can embryonic stem cells come from umbilical cords?

Embryonic stem cells come from umbilical cords in small quantities, which are harvested by collecting cord blood.

What is the difference between adult stem cells and embryonic stem cells?

Embryonic stem cells (ESC) comes from embryos, and adult stem cells (ASC) come from adults. To get ESC, you have to destroy and embryo. Adults have stem cells throughout their body. They can easily be removed without inflicting harm on the adult.

What are five different types of stem cells?

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.

The stem cells come from newly fertilized eggs. What do those eggs do?

Stem cells come from newly fertilized eggs because those eggs divide and evolve into more specialized cells.

Where stem cells come from for research?

most human embryonic stem cells used for research come from unused IVF eggs. there are then strict regulations on how long these cells are allowed to grow for and what you are wllowed to do with them in the meantime and how you get ride of them when you are done, but these vary from country to country. there are other types of stem cells that are presnt in adults though (like hemopoatic (forgive my spelling) stem cells). much research has been carried out on these adult stem cells too. also, stem cells can be studied in living organisms (for example fruit flies or mice) and therefore come from (and are often not removed from) animals.

Are fetal cells only source of 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

What are the three types of stem cells in adults?

How do adult stem cells differ from embryonic stem cells?

Adult stem cells are harvested from newborn's cord blood or human bone marrow while embryo stem cells come from the inner cell mass of a human embryo. No fetus is killed to use the stem cells, but the embryo cannot function and must be destroyed without a inner cell mass.

Why stem cell are called stem cells?

The stem of a plant is full of undifferentiated cells. Thus the name stem cells.

Where do red blood cells from?

Both red and white blood cells come from blood stem cells in the bone marrow.

Can body tissues be grown from stem cells?

All of your cells come from stem cells, so yes, you can grow more tissue from an organ from them. In fact this is what happens when your body tries to repair damage.
