Stem Cells and Nanotechnology in Spinal Injury Repair: Difference between revisions

[[File:Stem-cells.jpg|thumb|200px|right|Stem cells replicated in a lab.]]  The idea of using stem cells for the the purpose of regenerating organs was born in the early 21st century. Scientists studied creatures that were able to regenerate whole body parts in hopes of understanding how such a remarkable feat of biology could be applied to the human body. This research also revealed the amazing ability of the human liver to regenerate itself when a segment of it was removed. Though it never resumes its original shape, it regains its original mass <ref>[https://stemgenex.com/studies/multiple-sclerosis-stem-cell-studies/#tab-5.

Stem cells were explored for the treatment of multiple sclerosis, an autoimmune condition in which the immune system incorrectly saw the myelin sheath surrounding nerve cells as foreign and began attacking this protective coating, resulting in damage to the nerve cells and leading to slowing of messages to and from the brain. The use of mesenchymal stem cells has been shown to repair this damage as well as repairing the immune system, preventing further attacks. These cells are found in several places in the humanoid body, including in bone marrow, skin, and fat tissue and they produce cells that help other stem cells to function correctly. The theory behind the application of this method is that a scientist expands the cells in a laboratory and injects them into the space surrounding the spinal cord (intrathecal) with an end goal of inhibiting immune response and augmenting tissue repair <ref>[http://www.nationalmssociety.org/Research/Research-News-Progress/Stem-Cells-in-MS "Stem Cells in MS"], National Multiple Sclerosis Society, SD 2394</ref>.

One of the most progressive uses of the technology was engineered nanoparticles designed to deliver a variety of elements such as heat and drugs to specific cells, leading to direct treatment of these cells in hopes of reducing damage to healthy cells in the body and allowing for earlier detection of disease or mutations in cells. <ref>[http://www.understandingnano.com/medicine.html "Nanotechnology in Medicine: Nanomedicine"], Understanding Nano, SD 2394</ref>

Another important aspect of the field, nano-gel, injected as a liquid into the spinal column, supports stem cells in that it not only prevents scar tissue from forming as an injury site heals, it also encourages the stem cells to create new cells that produce myelin, the material that surrounds the nerves of the spinal cord and prevents them from being damaged. The gel is often used in combination with stem cell therapies to heal spinal cord injuries, including severed nerve fibers and supports the growth of axioms both up into the brain and down to the legs, bridging the connection. Patients who were previously paralyzed are able to regain some, if not all of their mobility. <ref>[https://www.sciencedaily.com/releases/2008/04/080402114819.htm  "Promising New Nanotechnology For Spinal Cord Injury"], ScienceDaily, SD 2385</ref>

Innovations in this field are fairly recent. The first functioning genetronic replicator was designed and constructed by Doctor Toby Russel in the mid-24th century. Dr. Russel's theory was that the device could scan a person's DNA and damaged organs, then using this information to replicate a new healthy organ. The first recipient to survive the use of this technology was a Klingon male, Worf, in 2368. He was struck by a falling container and, as a result, was partially paralyzed when the container broke his spine. In the case of the Klingon male, Dr. Russel proposed the replication of a new spinal column to give the male full mobility back. The patient nearly died during the operation, but survived due to redundancies in his biological systems. The process was later refined by Doctor Simon Tarses when it was used in combination with nanotechnology to repair the damaged portions of a Bajoran female's spine when it was severed by Taran'atar's attack <ref>[http://memory-beta.wikia.com/wiki/Genitronic_replication "Genetronic Replication"], Memory Beta, SD 2394</ref>

Prior to her surgery, the patient experienced significant difficulties with mobility that, at times, impeded her ability to perform her duties. The patient also experienced chronic pain at the site of the injury and stiffening of her limbs. The continued degradation of the nanites used to keep the patient mobile meant that had she not attempted the procedure, she would have experienced near complete paralysis and would likely have been confined to a hoverchair until an alternate solution could be found. Post-surgery, the patient reports a drastic decrease in pain as well as increased mobility. The use of physical therapy techniques has helped the patient to regain much of her previous mobility and she continues to make excellent progress. The patient has reported only mild side effects from the procedure such as moderate at the surgical site, fatigue, and headaches, none of which are unexpected. The patient attends twice month appointments to monitor healing progress via deep scans and evaluate for potential signs of Failed Back Surgery Syndrome (FBSS) <ref>[https://www.laserspineinstitute.com/back_problems/fbss/ "What Is Failed Back Surgery Syndrome (FBSS)?"] Laser Spine Institute, Stardate 2394</ref>, in which the patient experiences unusual chronic pain post-surgery. Despite these risks, the patient's primary physician anticipates that she will make a full recovery.
