Bone marrow
Bone marrow is a semi-solid tissue which may be found within the spongy or cancellous portions of bones. In birds and mammals, bone marrow is the primary site of new blood cell production or hematopoiesis. It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells. In adult humans, bone marrow is primarily located in the ribs, vertebrae, sternum, and bone…

Are stem cell-based therapies the future of CVD treatment?
Many unsuccessful attempts have been made to intervene in the disease's pathogenesis and treatment. Stem cell-based therapies, as a regeneration strategy, cast a new hope for CVD treatment. One of the most well-known stem cells is mesenchymal stem cells (MSCs), classified as one of the adult stem cells and can be obtained from different tissues.
What are stem cell-based therapies?
Stem cells have the ability to self-renew. Unlike muscle cells, blood cells, or nerve cells—which do not normally replicate— stem cells may replicate many times. When a stem cell divides, the resulting two daughter cells may be: 1) both stem cells, 2) a stem cell and a more differentiated cell, or 3) both more differentiated cells.

Why are stem cells illegal?
The court order is the outcome of a lawsuit originally filed last August against the Department of Health and Human Services (HHS) and the National Institutes of Health (NIH) in Bethesda, Maryland, which contends that federal funding for research on human embryonic stem cells is illegal because it requires the ...Aug 24, 2010
What is stem cell therapy?
Stem cell therapy, also known as regenerative medicine, promotes the repair response of diseased, dysfunctional or injured tissue using stem cells or their derivatives. It is the next chapter in organ transplantation and uses cells instead of donor organs, which are limited in supply.
Where are adult stem cells found?
Adult stem cells. These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body. Until recently, researchers thought adult stem cells could create only similar types of cells.
What are the master cells of the body?
Stem cells are the body's master cells. All other cells arise from stem cells, including blood cells, nerve cells and others. Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called ...
How can stem cell research help?
Researchers and doctors hope stem cell studies can help to: Increase understanding of how diseases occur. By watching stem cells mature into cells in bones, heart muscle, nerves, and other organs and tissue, researchers and doctors may better understand how diseases and conditions develop. Generate healthy cells to replace diseased cells ...
What is the name of the cell that divides to form more cells?
Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. These daughter cells either become new stem cells (self-renewal) or become specialized cells (differentiation) with a more specific function, such as blood cells, brain cells, heart muscle cells or bone cells.
How many cells are in an embryo?
Embryonic stem cells. These stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body.

Adult stem cells have been identified in many organs and tissues and are generally associated with specific anatomical ...
How do stem cells proliferate?
Stem cells can proliferate in laboratory environments in a culture dish that contains a nutrient broth known as culture medium (which is optimized for growing different types of stem cells). Most stem cells attach, divide, and spread over the surface of the dish.
Where are adult stem cells found?
Adult stem cells are found in a tissue or organ and can differentiate to yield the specialized cell types of that tissue or organ. Pluripotent stem cells. Early mammalian embryos at the blastocyst stage contain two types of cells – cells of the inner cell mass, and cells of the trophectoderm. The trophectodermal cells contribute to the placenta.
What happens when a stem cell divides?
When a stem cell divides, the resulting two daughter cells may be: 1) both stem cells, 2) a stem cell and a more differentiated cell, or 3) both more differentiated cells. What controls the balance between these types of divisions to maintain stem cells at an appropriate level within a given tissue is not yet well known.
What is cell based therapy?
Cell-based therapies. An important potential application is the generation of cells and tissues for cell-based therapies, also called tissue engineering. The current need for transplantable tissues and organs far outweighs the available supply. Stem cells offer the possibility of a renewable source.
What is the NIH funding?
NIH conducts and funds basic, translational, and clinical research with a range of different types of stem cells. NIH-supported research with human pluripotent stem cells is conducted under the terms of the NIH Guidelines for Human Stem Cell Research. NIH awards are listed in various categories of stem cell research through the NIH Estimates of Funding for Various Research, Condition, and Disease Categories (RCDC). NIH also supports a major adult stem cell and iPSC research initiative through the Regenerative Medicine Innovation Project.
