A stem cell is a cell that has the ability to continuously divide and differentiate (develop) into various other kind(s) of cells and tissues. Like a blank microchip that can ultimately be programmed to perform any one of a number of specialized tasks, stem cells are undifferentiated, 'blank' cells that do not yet have a specific physiological function. When the proper conditions occur in the body or in the laboratory, stem cells begin to develop into specialized tissues and organs. Stem cells are also self-sustaining, replicating through cell division.
These unique characteristics are why stem cell research holds such great promise for the treatment of life-threatening and debilitating diseases such as Alzheimer's disease, cancer, Parkinson's disease, and juvenile Diabetes. Understanding what the genetic and biochemical signs are that trigger stem cell differentiation may allow researchers to one day program new cells to repair damaged tissues and organs, and to better understand disease processes. Here is a current list of the sources of stem cells:
Stem cells are typically obtained from embryos that are a few days old, known as blastocysts. At this stage, the embryo has developed into a hollow ball of cells with an inner cell mass that contains embryonic stem cells. These cells can be extracted and grown in laboratories for research and potential therapeutic purposes.
Cloning to produce embryonic stem cells is called therapeutic cloning. This process involves creating a clone of a donor’s cells to generate embryonic stem cells that can be used for medical research and potential treatments.
Therapeutic cloning is important to enhance the understanding of stem cells and how they and other cells develop.
Adult stem cells have more limited differentiation potential compared to embryonic stem cells, making them less versatile for therapeutic cloning. Additionally, adult stem cells are often harder to manipulate in the lab and may not replicate as easily as embryonic stem cells. However, adult stem cells have the advantage of being less likely to be rejected by the recipient's immune system, which can be a benefit in certain therapeutic applications.
Adult stem cells, also known as somatic stem cells, are obtained from tissues in the body such as bone marrow, adipose tissue, or blood. These stem cells have the ability to differentiate into a limited range of cell types depending on their origin. They are used in regenerative medicine and research due to their potential to repair damaged tissues and organs.

Therapeutic cloning is a process that involves creating embryos for the purpose of harvesting stem cells to use in medical treatments. These stem cells can potentially be used to generate tissues or organs to replace damaged or diseased cells in the body. Therapeutic cloning is a promising technology for regenerative medicine but is still in the experimental stages.

Peripheral blood stem cells (PBSCs) are obtained from circulating blood rather than from bone marrow, but the amount of stem cells found in the peripheral blood is much smaller than the amount of stem cells found in the bone marrow.
Embryonic stem cells can be obtained from early-stage embryos. Adult stem cells are found in various tissues throughout the body, such as the bone marrow or brain. Induced pluripotent stem cells are created by reprogramming adult cells, like skin cells, to develop stem cell properties.
Stem cells are undifferentiated cells that have the ability to develop into various types of specialized cells in the body. They play a crucial role in growth, repair, and healing processes. Stem cells can self-renew and multiply, making them valuable for medical research and potential therapeutic applications.
The type of stem cells that can develop into any kind of cell in the human body or the placenta are called pluripotent stem cells. These include embryonic stem cells, which are derived from the early stages of an embryo, and induced pluripotent stem cells (iPSCs), which are adult cells reprogrammed to an embryonic-like state. Pluripotent stem cells have the potential to differentiate into all cell types, making them valuable for research and potential therapeutic applications.
Yes, stem cells can be obtained from bone marrow. Bone marrow contains hematopoietic stem cells that have the ability to generate different types of blood cells. These stem cells can be used for various medical treatments, such as bone marrow transplants for patients with certain blood disorders or cancers.
