Stem Cells Introduction The world is a dangerous place. Anything can happen anytime and anywhere at any given place. Accidents and incidents happen and injuries do occur. These events can happen within sports, vacation trips, car accidents, and various coincidences that could or may occur. In this case the subject has received a spinal injury from a very severe accident. This essay will show the different types of stem cells comparing and contrasting these types and how they can be used as well. An individual will be allowed to see the negatives and the positives of each stem cell and see how they can enhance spinal injuries for this individual. Overall, the reader will be allowed to view the positives and negatives, different types of stem cells, and finally be able to decide the best course of action for the individual. This will also be followed up with a letter stating the next step for our individual so they can be rest assured and chose the best course of action overall for their future. Abstract The first thing to do is develop a quick abstract overall about our topic. Spinal cord injury also known as (SCI) disrupts the long axonal tracts of the spinal cord leading to devastating loss of function. Cell transplantation in the injured spinal cord has the potential to lead to recovery after SCI by use of variety mechanisms. One such strategy that can be used is the formation of neuronal relays between injured long tract axons and denervated neurons. The idea of creating a neuronal relay was first proposed over twenty-five years ago when fetal tissues were first used successfully and transplanted into an injured rodents’ spinal cord. This allowed advances in labeling of grafted cells and future development of neural stem cell culturing techniques that in turn have

Stem Cells improved the ability to create and refine such relays. Several recent studies have examined the ability to create a novel neuronal circuit between the injured axons and denervated targets. This approach is now seen as an alternative to long-distance regeneration of damaged axons that may provide a meaningful degree of recovery without direct recreation of lost pathways and enhance the spine. This brief review has examined the contribution of fetal grafting to current advances in neuronal grafting. The particular interest can be focused upon the ability of transplanted neurons derived from fetal grafts, neural precursor cells and neural stem cells that reconnect long distance motor and sensory pathways of the injured spinal cord so that the individual can recover using technology. Two Main Stem Cells In order to understand stem cells, the first thing to know is that there are two main stem cell types. These are embryonic stem cells (ES) cells and adult stem cells (i.e., somatic stem cells). There are other types, such as induced pluripotent stem cells
