Recommended: Creation of human organs essay
Organogenesis takes its roots from two Greek words: organon, an instrument, tool, or organ, and genesis, a beginning or creation. With this in mind, one can intuitively infer the basic meaning of the word organogenesis; that is, the creation of an organ. What it means in context to medicine, however, may not be so easily predicted. If any man (or woman, for that matter) of medicine fifteen years ago was asked about the meaning of organogenesis, he or she may tell you that it is the development of organs in an embryo. This is because just a few years ago, the only known way of creating organs was to bring a new organism into the world. If the question was asked today, however, the response might be something like “Which kind?”, as there now exists more than one way to create organs. The field of bioengineering has produced amazing advancements in regenerative medicine. The knowledge of the medical field is now to a point where organs can be created in a lab from only artificial materials and stem cells. This growing of organs is now referred to as organogenesis, and it is the solution to a myriad of medical problems. A Brief History of Regenerative Medicine Since the beginning of civilization, doctors have been searching for ways to repair, recreate, or otherwise replace damaged parts of the body. Procedures which seem complex even by today’s standards, such as a skin graft for facial reconstruction, have been performed since as long as 1000 years ago. The concept of regeneration has even been acknowledged as far back as the 8th century BC in the Greek myth of Prometheus, in which Prometheus was punished by having an eagle, Ethos, eat his liver each day, only to have it regenerate by nighttime and be pecked out again the next day.... ... middle of paper ... ...n easily printed and transplanted, more complex organs cannot yet be made due to their many parts. Currently, kidneys and livers are in highest demand, but are unable to be printed (Organ Bioprinting). The best course of action currently is to inject stem cells into patients with liver or kidney damage, rather than trying to print new organs. Bioengineering is a truly fascinating and prolific field, from which we will be sure to see many advances in the future. Currently, researchers are even devising a process of scanning large wounds and printing stem cells directly onto the patient to repair it. Many things that were previously science fiction are now becoming a reality thanks to a massive team of doctors, researchers, and engineers working to implement organogenesis into common medicine, truly making this exciting new process the future of regenerative medicine.
...m these advancements that are from human body parts. Instead, it is imperative to honor and preserve those who have made these interventions possible
The cells unique nature has scientists intrigued to do research with the focus of finding a way that these cells can be used to replace patients’ injured or diseased tissues. Advancement is made to all the three types of stem cells namely embryonic stem cells, adult stem cells in addition to induced pluripotent cells. Embryonic cells are the building blocks of an embryo that is developing, and can develop into almost all body cell types. Somatic cells are found in the body tissues. They renew and regenerate in healthy bodies. The third type which is induced pluripotent is genetically modified embryo cells from skin cells.2 Research on these cells are geared towards saving humanity; a noble course.
Brendan Maher, in his article “How to Build a Heart” discusses doctor’s and engineer’s research and experimentation into the field of regenerative medicine. Maher talks about several different researchers in this fields. One is Doris Taylor, the director of regenerative medicine at the Texas Heart Institute in Houston. Her job includes harvesting organs such as hearts and lungs and re-engineering them starting with the cells. She attempts to bring the back to life in order to be used for people who are on transplant waiting lists. She hopes to be able to make the number of people waiting for transplants diminish with her research but it is a very difficult process. Maher says that researchers have had some successes when it comes to rebuilding organs but only with simples ones such as a bladder. A heart is much more complicated and requires many more cells to do all the functions it needs to. New organs have to be able to do several things in order for them to be used in humans that are still alive. They need to be sterile, able to grow, able to repair themselves, and work. Taylor has led some of the first successful experiments to build rat hearts and is hopeful of a good outcome with tissue rebuilding and engineering. Scientists have been able to make beating heart cells in a petri dish but the main issue now is developing a scaffold for these cells so that they can form in three dimension. Harold Ott, a surgeon from Massachusetts General Hospital and studied under Taylor, has a method that he developed while training. Detergent is pumped into a glass chamber where a heart is suspended and this detergent strips away everything except a layer of collagen, laminins, and other proteins. The hard part according to Ott is making s...
...velopment of tissues to replace damaged organs in the human body. Scientists have discovered for the first time how stem cells could be generated from embryo’s that were produced using adult stem cells.
Organ development is the moving of an organ beginning with one body then onto the following or from an advocate site to another range on the individual's own specific body, to supplant the recipient's hurt or missing organ. Organs and tissues that are transplanted inside the same individual's body are called autografts. Transplants that are starting late performed among two topics of the same species are called allografts.
...ing medicines (especially for soldiers) and there are still so many casualties out on the battlefield?” Well, they sure have the money in the right place, but that is not all it takes. It takes the brainpower of many diverse scientists from all around to master the regenerative medicinal method. With its clinical team of scientists, AFIRM’s goal is to, over the next 5 years, develop clinical therapies that will prove useful when focusing on the 5 areas: improving skin regeneration for burn injuries, restoring function to severely traumatized limbs, reconstruction for facial and skull injuries through tissue regeneration, create new treatments to prevent rejection of "composite" transplants such as face and hands and finally reconstruction of the genital and urinary organs and lower abdomen.
Reader! It has come to my attention that the human world has been thrown into major conflicts surrounding the ethics of restoring the function of the face, using microsurgery, to those with severe disfigurements (Lamparello). This revolution of the science that led to my creation has almost rendered me speechless! No longer will patients feel hideous in their own skin because of unforeseen circumstances. Oh, how it is a horrid life to live, to be unaccepted by your fellow man, no matter how much YOU try and assimilate! Facial reconstruction is an innovative process that can improve the self-confidence of those whom were born naturally disfigured or were disfigured later in their lifetime. Face transplantation implores my interest simply because of how close it pounds at my wretched heart. When I escaped to a land far from the accursed laboratory I was “born” in, I found documents belonging to my creator that detailed his disgusted thoughts during my creation and final “birth”. It was exceptionally difficult to study his horror-stricken account of my hideous appearance (Shelley 34). When he’d lain his eyes on his obsession for the first time, he promptly disregarded his previous claims of my
The human body endures a great deal of wear and injury during its lifetime. It is for this reason that the body has several tissues that are capable of regeneration. Bone is one of those tissues that receives extensive use so it is necessary that it is strong in order to carry out its functions; however, it will occasionally face injury. Although our bones are capable of regeneration, a new method would help the elderly and others that have a more difficult time healing after injury. I viewed a “TED Talk” lecture, which discussed a new way of regenerating bone with the help of our own bodies. Molly Stevens, the head of a biomaterials lab, presented “A New Way to Grow Bone” where she discussed a new technique called “in vivo bioreactor”. She also answered why this new procedure is beneficial. Researchers like Stevens are constantly trying to find innovative new techniques and they do this by asking questions. The question that Stevens presented in the video was an intriguing one: “Can we recreate the regeneration of bone on demand and transplant it?”.
The first organ transplants can be traced back to the ancient times where Ancient Greeks, Romans and Chinese myths features accounts of transplants accomplished by gods and healers which involves cadavers and animals though these claims were thought to be fictitious, Indian doctors may likely begun transplanting skin from one part of the body to another to repair wounds and burns around 800 B.C. It is during the 16th Century that Italian surgeon Gasparo Tagliacozzi, also referred to as the father of plastic surgery performed reconstruction of noses and ears by transplanting the patient’s own skin tissues from his arm to the patient’s nose and ears. He dis...
The field of bioprinting, using 3D printing technology for producing live cells with extreme accuracy, could be the answer to many of the problems we as humans face in the medical field. It could be the end to organ waiting lists and an alternative for organ transplants. In 3D printing technology lies the potential to replace the testing of new drugs on animals. However, the idea of applying 3 dimensional printing to the health industry is still quite new and yet to have a major impact. Manufacturing working 3D organs remains an enormous challenge, but in theory could solve major issues present today.
The changes it could bring are amazing, there is really no reason to stop learning more about helping to heal the human body. Works Cited Work Citations The "Genetic Engineering" 123HelpMe.com. 08 May 2017 http://www.123HelpMe.com/view.asp?id=67046>. King James Version. Arizona:
One of the most beneficial aspects to cloning is the ability to duplicate organs. Many patients in hospitals are waiting for transplants and many of them are dying because they are not receiving a needed organ. To solve this problem, scientists have been using embryonic stem cells to produce organs or tissues to repair or replace damaged ones (Human Cloning). Skin for burn victims, brain cells for the brain damaged, hearts, lungs, livers, and kidneys can all be produced. By combining the technology of stem cell research and human cloning, it will be possible to produce the needed tissues and organs for patients in desperate need for a transplant (Human Cloning). The waiting list for transplants will become a lot shorter and a lot less people will have to suff...
Throughout the last two centuries many scientific advances have been made in terms of organ transplants. Today transplants of organs such as kidneys, livers, hearts, pancreata, intestine, and lungs are considered routine medical treatment and are performed daily. In 1954 the first successful transplant, a kidney transplant, was performed by Doctor Joseph E. Murray in Boston, Massachusetts. This was a breakthrough in science and was just the beginning of a series of saved lives and extended opportunities. The number of first time transplants continued throughout the years, as did the success rate of transplants overall, especially in the 1980’s and 90’s. The research recently has slowed down now that the procedure of a transplant is so routine but continues still to be bettered by scientists and their technology and will be at alm...
Synthetic biology, also known as synbio, is a new form of research that began in the year 2000. The Action Group on Erosion, Technology and Concentration (ETC Group) says that synthetic biology is bringing together “engineering and the life sciences in order to design and construct new biological parts, devices and systems that do not currently exist in the natural world’ (Synthetic Biology). Synthetic biology is aiming to create safer medicines, clean energy, and help the environment through synthetically engineered medicines, biofuels, and food. Because synthetic biology has only existed for fourteen years, there is controversy involving its engineering ethics. In this literature review, I am going to summarize and correlate the International Association for Synthetic Biology (IASB) Code of Conduct for Gene Synthesis, the impact of synthetic biology on people and the environment, and the philosophical debates.
The field of regenerative medicine encompasses numerous strategies, including the use of materials and de novo generated cells, as well as various combinations thereof, to take the place of missing tissue, effectively replacing it both structurally and functionally, or to contribute to tissue healing[29]
