what are the advantages and disadvantages of adult stem cell?

what are the advantages and disadvantages of adult stem cell? | biological science assignment | Scoop.it
The advantages of using an adult stem cell are that you can use them for current treatments/therapies and that you do not have to deal with the ethical issues of using embryonic stem cells.

Adult stem cell - Wikipedia, the free encyclopedia

Adult stem cells are undifferentiated cells, found throughout the body after development, that multiply by cell division to replenish dying cells and regenerate damaged tissues. Also known as somatic stem cells (from Greek Σωματικóς, meaning of the body), they can be found in juvenile as well as adult animals and human bodies.

Scientific interest in adult stem cells is centered on their ability to divide or self-renew indefinitely, and generate all the cell types of the organ from which they originate, potentially regenerating the entire organ from a few cells. Unlike embryonic stem cells, the use of adult stem cells in research and therapy is not considered to be controversial, as they are derived from adult tissue samples rather than destroyed human embryos. They have mainly been studied in humans and model organisms such as mice and rats.

A stem cell possesses two properties:

Embryonic stem cell - Wikipedia, the free encyclopedia

Embryonic stem cells (ES cells) are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage embryo.[1] Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells. Isolating the embryoblast or inner cell mass (ICM) results in destruction of the fertilized human embryo, which raises ethical issues. Those issues include whether or not a human life at the embryonic stage should be granted the moral status of a human being.[2][3]

Human ES cells measure approximately 14μm while mouse ES cells are closer to 8μm.[4]

Embryonic stem cells are distinguished by two distinctive properties:
