Better, but mixed, results came from research using muscle stem cells.

The best animal results yet May came when embryonic stem cells were transplanted within a man-made 3D structure into damaged hearts of rodents which had suffered heart attacks. In the same month there were reports of successful human grafts, where it was shown that new heart cells were derived from injected umbilical cord stem cells.

Essay: Benefits of Stem Cell Research

In animals, fetal heart cells graft easily into the heart, adopt the identity of adult heart cells, and become electrically coupled. However, their use in humans is ethically problematic. The search is now on for heart precursor cells and to discover the signals that guide the way they migrate, renew themselves, and become adult heart cells.

New muscle cells have been formed in mouse muscle in the test-tube, and in living mice. In both cases the cells were reprogrammed by signals from surrounding cells, suggesting that adult tissues may be able to instruct transplanted cells to adopt the fates appropriate to their new location.

Muscle regeneration has also resulted from injecting several types of stem cells — from bone marrow, from human knee joints, and from newborn mouse muscles — repairing damage similar to muscular dystrophy. Injured muscle seems to send distress signals around the body that summon the cells. But there are still doubts about whether adult stem cells can be used to provide effective treatments for diseases such as muscular dystrophy.

The brain is immune privileged, which means that it does not reject cells from other animals or even other species, and this makes it a prime target for stem cell therapy.

Fetal brain stem cells are relatively easy to collect and grow in the laboratory, and can divide indefinitely with no tendency to tumour growth. Research to date shows similar problems to that of heart research. Stem cells transplants have improved but not cured most but not all mice with Parkinson's, stroke, EAE an induced form of multiple sclerosis spinal cord injury, motor neurone disease and other conditions. Some of the injected stem cells create an environment that protects and aids the survival of the host nerve cells.

In the spinal cord, only a tiny proportion of injected cells become new motor nerves that penetrate muscle. In normal brains after injury nerve stem cells cluster round the injury site and generate new stem cells, though it is self-evident that they do not produce sufficient to fully repair the damage done. In the eye, injected stem cells attach to a type of retinal cell called astrocytes. However, unless they are genetically modified, they form new blood vessels, which can obstruct clear vision.

In May it was reported that three cancer patients, all female, who had received stem cell transplants from their brothers formed new brain support cells. The new cells contained Y-chromosomes, which proves they were of male origin, but the findings do not rule out fusion between bone marrow and other stem cells.

What are stem cells and why are they important?

Purkinje nerve cells in the cerebellum can fuse with bone marrow cells in both mice and humans. Research in rats and mice shows that pancreatic, liver, and bone marrow stem cells can transform into insulin-producing cells. Stem cell research may also cure Hirschprung disease, a genetic condition wherein a defect stops nerve stem cells forming nerves that control the small intestine.

With diabetes, some researchers have found that bone marrow stem cells transdifferentiated into pancreatic beta cells, whereas other research teams have failed to see this. Because many diseases result from the death or dysfunction of a single cell type, scientists believe that the introduction of healthy cells of this type into a patient may restore lost or compromised function.

The research of stem cells is a new study proving the a stem cell a primitive type of cell can be coaxed into developing into most types of cells found in the human body.

However, ethics comes into play when we are faced with the legitimate question regarding either side of the positive and negative opinion, the problem truly lies in the actually source of the stem cells. Those who are considered pro-choice regard that human personhood to occur much later in the pregnancy. Thus, killing a recently fertilized embryo is not murder of a human person.

This would allow federal researchers to extract stem cells from embryos.
