Benefits of Stem Cell Research Research with embryonic stem cells may lead to new, more effective treatments for serious human ailments and alleviate the suffering of thousands of people. Diseases such as juvenile diabetes, Parkinson's disease, heart failure and spinal cord injuries are examples.

Stem cells could help medicine in three general ways: cell-based therapies, drug discovery and basic knowledge. Cell therapies would use stem cells, or cells grown from stem cells, to replace or rejuvenate damaged tissue. Scientists also want to use stem cells to understand disease and find drugs that might treat it.

How might induced pluripotent stem cells (iPS) resolve the debate about using stem cells for medical treatments? ... Cells are taken and reverted into stem cells instead of being harvested from human embryos.

SCL: What are the main arguments for and against embryonic stem cell research? MS: Proponents argue that embryonic stem cell research holds great promise for understanding and curing diabetes, Parkinson's disease, spinal cord injury, and other debilitating conditions.

Mesenchymal stem cells (MSCs) are found in many parts of the body and are usually taken from bone marrow, skin and fat tissue. They can produce many different types of cells, including muscle and cartilage. Early research suggests they might help to promote myelin repair and have a positive effect on the immune system.

The primary function of adult (somatic) stem cells is to maintain tissue homeostasis by replenishing senescent or damaged cells. For example, normal repair and exercise-induced cellular hypertrophy in muscle is mediated by stem cells.

Induced pluripotent stem cells are widely used in therapeutics for disease modeling, regenerative medicine, and drug discovery (Figure ​4). There are many applications of iPSCs in the fields of gene therapy, disease modeling and drug discovery.

What are the 3 characteristics of all stem cells? Stem cells are unspecialized, can divide and renew themselves for long periods of time, and can be induced to become differentiated cells with specialized functions.

Stem cell treatments for back pain may be an excellent alternative to spinal fusion and other back surgery when there is no instability in the spine and there is not a large disc herniation present. Stem cell therapy is not a recommended treatment option for spinal stenosis, scoliosis and spondylolisthesis.

The Bad. One of the bad things about stem cells is that they have been over-hyped by the media in regard to their readiness for treating multiple diseases. As a result, stem cell tourism has become a lucrative yet unethical business worldwide.

They have become an important tool for modelling and investigating human diseases, as well as for screening drugs. Improved ways of making the cells, along with gene-editing technologies, have turned iPS cells into a lab workhorse — providing an unlimited supply of once-inaccessible human tissues for research.

Embryonic stem cell research requires that specific cells be harvested from human embryos in order to explore the possibility of medical cures for some human degenerative diseases, and by removing the necessary stem cells, the embryo ceases living.

Disadvantages. The main disadvantage of stem cell research has to do with the way that they're acquired-that is, it involves the destruction of human embryos. This makes it immoral for those who believe that life begins at contraception.
