Abstract

This paper addresses the topic of stem cell use combined with nanotechnology as a possible treatment for spinal injury that would normally be inoperable and remain a lifelong impediment to the patient. Through extensive research and trials, the researcher was able to replace the damaged spinal column using genetronic technology and program the nanites to work in conjunction with the stem cells to stimulate regrowth of previously destroyed myelin sheath as well as using the nanites to prevent mutation of cells which could lead to cancerous growths. The results of the treatment and surgery are detailed in this dissertation.

Introduction

The use of genetronics to replace the spinal column bone and the use of both stem cells and nanites to encourage regrowth of myelin sheath surrounding the nerves in the spine is a risky endeavor in a single species patient. If not done correctly, it can lead to permanent paralysis or even death. The patient's hybrid physiology led to even greater risk of complications. Until the surgery, the patient had been using nanites to keep herself mobile, programming and injecting herself with the mini-machines. However, her necessarily strenuous activity as a result of her occupation (Starfleet officer) caused degradation to occur faster than the nanites could repair. The nanites themselves began to malfunction and the patient soon found herself unable to keep up with the demands of her worsening injury, thus necessitating an alternative measure to ensure she maintained her mobility. The patient was an otherwise healthy Al-Leyan/Human female in her late 20s who eats a balanced diet and engages in regular exercise. After extensive research and input from both Medical and Engineering professionals, the patient was presented with two treatment options, as outlined below in the methods section of this paper.

Definitions

For the purposes of this paper, nanites are tiny machines programmed for a specific purpose. In this case, they protect healthy cells and destroy mutated cells to prevent the unhealthy cells from overtaking the body, leading to serious repercussions, such as cancer. While this requires routine check-ups for the remainder of the patient's life, the need for nanite injections will be decreased in frequency. Further, regeneration is the regrowth or repair of an organ damaged by any means.

Literature Review

Research on this specific topic has been minimal given its controversial nature. However, extensive research has been done on both the use of stem cells to regenerate damaged organs and on nanotechnology in the field of medicine.

Stem Cells

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 (StemGenex, 2393).

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 (National Multiple Sclerosis Society, 2394).

Nanotechnology

Nanotechnology has also found applications in medicine since the early 21st century when mankind first imagined the use of nano (mini) robots to repair the body at a cellular level. 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. (Nanotechnology in Medicine: Nanomedicine, 2394).

Genetronics

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 (Memory Beta, 2394).

Conceptual Framework

As can be seen by the patient's x-ray immediately following her injury, she suffered broken lower lumbar vertabrae and nerve damage as a result of her fall. Though doctors were able to reconstruct most of her damaged spinal column, the fragile nature of the vertabrae combined with the severe nerve damage offered no hope that the patient would be able to regain her mobility. This was only achieved by the introduction of specifically-programmed nanites which were able to reverse the nerve damage and strengthen the vertabrae. However, the nature of the injury resulted quicker-than-usual degradation of nerve fibers and already-weak bone. Despite daily injections of nanites with the intention of slowing the damage, all attempts have proven to do so only temporarily. It was estimated that without drastic action, the patient would lose mobility completely by age 30.
