Though great progress has been made in medicine, current evidence-based and palliative treatments are increasingly unable to keep pace with patients' needs, especially given our aging population. There are few effective ways to treat the root causes of many diseases, injuries and congenital conditions. In many cases, clinicians can only manage patients' symptoms using medications or devices.
Regenerative medicine is a game-changing area of medicine with the potential to fully heal damaged tissues and organs, offering solutions and hope for people who have conditions that today are beyond repair. Regenerative medicine itself isn't new — the first bone marrow and solid-organ transplants were done decades ago. But advances in developmental and cell biology, immunology, and other fields have unlocked new opportunities to refine existing regenerative therapies and develop novel ones. According to The Center for Regenerative Medicine takes three interrelated approaches. The first approach is the Rejuvenation. Rejuvenation means

Stem cells are a key component of regenerative medicine, as they open the door to new clinical applications. Regenerative medicine teams are studying a variety of stem cells, including adult and embryonic stem cells. Also being studied are various types of progenitor cells, such as those found in umbilical cord blood, and bioengineered cells called induced pluripotent stem cells. Each type has unique qualities, with some being more versatile than others. Many of the regenerative therapies under development in the Center for Regenerative Medicine begin with the particular patient's own cells. For example, a patient's own skin cells may be collected, reprogrammed in a laboratory to give them certain characteristics, and delivered back to the patient to treat his or her
The first type of stem cell, an embryonic stem cell, is known for being able to continuously multiply, as well as for being pluripotent. They can be “derived in vitro from the blastocyst of an embryo usually left over from in vitro fertilization” (Forraz & McGuckin, 2011, p.61). Unlike other types of stem cells, embryonic stem cells have yet to be used in any kind of clinical treatment of patients. The high risks of “immune rejection” or “teratoma formation” are serious obstacles (Harris, 2009, p.182). The second type of stem cell, adult stem cells, is primarily considered to be multipotent and may be found in “specific adult human tissues” such as the skin or bone marrow, just to name a few. Over the last twenty years, the amount of scientific research and trials using adult stem cells has grown significantly, despite their lower potency than embryonic stem cells (Forraz & McGuckin, 2011, p.61). Lastly, cord blood stem cells, are technically considered to be a special type of adult stem cell, but their youthful properties give them “greater restorative and regenerative potential.” Directly following the birth of a child, these stem cells can be collected from the blood in the umbilical cord (Steenblock & Payne, 2006, p.9). Embryonic, adult, and cord blood stem cells
Stem cells are basically the building blocks of life. Some type of these cells can be engineered into any type of cell in the human body. There are three types of stem cells currently. Adult or somatic stem “cells can generate replacements for bone and muscle cells that are lost through injury, disease or normal wear and tear.” Another type of stem cells are embryonic stem cells. Embryonic stem cells “are “starter cells” that can be coaxed into becoming any of the specialized cells of the body, meaning they are “pluripotent.” The final type of stem cells are induced-pluripotent stem cells. Induced pluripotent stem cells “are adult stem cells that have been genetically altered to behave like embryonic stem cells”(National Institute of Health). Due to the advancement in medical technology scientists and doctors alike are now able to use stem cells for a variety of reasons like research and also in patient care. The benefits of this research can lead to the cure of diseases like diabetes, some cancers, and even neurodegenerative diseases like Parkinson’s Disease and spinal cord injuries. The controversy behind stem cells lie from where these stem cells come from. The source of stem cells are plentiful. Some stem cells can come from human embryos that are a few days old. Stem cells can also be engineered in a laboratory setting using the cells from human embryos. Also there are certain stem cells that can be harvested from adults and
There are several new methods that have been developed since the start of the highly controversial stem cell debate which rectifies the major differences on both sides. New solutions such as Induced Pluripotent Stem Cells (iPS) acts as an alternate method to embryonic research in that it uses cellular reprogramming of adult skin cells.“The benefit of iPS is that stem cells can be created without the use of embryos, however, the cells resemble embryos in that they can, theoretically and under the appropriate conditions, be made to differentiate into any type of cell found in the body ” (Phillips, 2010). . There are also techniques being developed that use amnionic fluid, or stem cell extraction techniques that do not damage the embryo, that also provide alternatives for obtaining viable stem cell lines ” (Phillips, 2010). The only caveat to all of these newly developed alternatives is that no solution has been studied long enough to claim that it can be an effective substitute 100%. “To begin with, demand for
Death is one of the most significant life events people experience. Most people want to die a peaceful death and desire the same outcome for their family and friends. Medical advancements have resulted in people living longer lives with chronic illnesses. Despite the advancements in medicine and the available treatments of today, sometimes the patient is still unable to escape intolerable suffering; the patient’s quality of life diminishes.
Stem cells are grown on Petri dishes in a laboratory and are never implanted in a woman’s uterus. These cells can be used to create stem cell lines that can grow indefinitely under optimal conditions (“Stem cells and diseases,” 2011). Embryonic stem cells can be obtained from existing stem cell lines (any group of cells that came from the same original embryo), aborted or miscarried embryos, unused in vitro fertilized embryos, and cloned embryos created from somatic cell nuclear transfer (the nucleus from an unfertilized egg is removed and replaced with a nucleus from an adult stem cell). This technique would be used for therapeutic cloning, which could grow organs or skin grafts for patients. However, the only research that is federally funded are a few embryonic stem cell lines created from unused embryos at in vitro fertilization (IVF) clinics before 2001 (Dunn, 2005; “Embryonic & fetal research laws,” 2008; Therapeutic cloning, 2009). These lines are not enough to allow scientists to fully explore and take advantage of potential findings.
“Through the isolation and manipulation of cells, scientists are finding ways to identify young, regenerating ones that can be used to replace damaged of dead cells in diseased organs. This therapy is similar to the process of organ transplant, only the treatment consists of the transplantation of cells rather than organs. The cells that have shown by far the most promise of supplying diseased organs with healthy cells are called stem cells.” (Chapter Preface)
Researchers successfully attained embryonic stem cells from the embryos of mice in 1981, which led to the discovery of this process in human beings in 1998 (National Institutes of Health, 2001). Embryonic stem cells are derived from an in vitro embryo between five days and seven weeks. Regenerative medicine can benefit greatly from the characteristics of embryonic stem cells. This process enables damaged organs and tissues to heal themselves with the help of implanted stem cells matching the organ (Hunziker, 2010, p. 1). There are two traits
Many of us have all heard the saying that a “lizard can lose its tail,” and bizarrely enough it will grow back. This was always considered impossible for humans, an idea belonging in the realm of science fiction, but now the regeneration of tissue is an extremely realistic possibility. Despite some opinions, this process does not happen naturally, or take place as cinematically as one might imagine. Over the past decade, there have been major advances in regenerative medicine, commonly known as stem cell research. Stem cells are undifferentiated cells within the body that have the capability to specialize into any tissue. They are most commonly found in cord blood, bone marrow, organ donations, placenta, and embryos . Stem cells are seen by some as a new miracle treatment, encouraging many countries to invest in their research.
The reason stem cells are such a big breakthrough in medical technology is that they are cells that have the remarkable ability to grow into just about any cell in the body (Introduction n. pag). In fact, stem cells that remain in the human body after birth “serve as a sort of internal repair system,” in many tissues and organs (Basics n. pag). This is an extremely efficient way of healing since stem cells can become
Advances in medical technology and processes are a double edged sword in regards to patient Quality of Life. Chronic-disease management has changed such that previously, people who would have died are now being kept alive due to the technological and medical advances dramatically increasing life expectancies over the centuries. With the advent of chemotherapy, surgeries and medications, life expectancy can sometimes be prolonged at the expense of Quality of Life.
Palliative care services began in the acute-care hospital setting and are now expanding to the outpatient setting in homes and outpatient clinics. Multiple professional medical organizations, such as the Institute of Medicine and the World Health Organization, are looking for improved palliative care services in various settings (Rabow et al., 2013). Patients worldwide require these services. In the past, palliative care was mostly recommended for patients with a cancer diagnosis. Today, it is being offered to patients with a wide range of life-limiting diseases such as congestive heart failure and chronic
Stem cell research is the future of medical and biological research and remedies, and it is fascinating to watch the progression of this new and important science as it unfolds. These cells were discovered in mouse embryos in the 1980s, and are remarkable because of their potential to grow into a variety of different kinds of cells within a body. Common in fetuses, and more rare in adult animals of all kinds, stem cells can be manipulated in useful ways to repair many tissues, dividing limitlessly for therapeutic purposes. When a stem cell divides, each new cell has the potential either to remain a stem cell or to differentiate into more specialized tissue, such as nerve, pancreas, bone marrow, or unique blood components. Initially
There is a need for evidence on palliative care because improving strategies could potentially improve the patients end of life care and could ensure that they die in a dignified
Many societies that are grappling with the challenge of a rapidly ageing population are increasing the demand for regenerative medicine, which holds the promise of growing tissue and organs in the laboratory and allows surgeons to safely implant them when the body is unable to heal itself. Traffic accidents and war amputations are also spurring interest in the field. Scientists are already able to engineer tissue using various biomaterials, and believe that stem cells, especially ones called induced pluripotent stem cells (adult cells that have been genetically reprogrammed to an embryonic stem cell-like state) provide another significant opportunity in this field.
Typically when most people think of regeneration, the thought of rebuilding comes into mind. In the same respect, a salamander possesses this ability and uses it to their advantage. Regeneration is the process of rebuilding certain cells, tissues or limbs. It’s an intricate progression that allows different animals to survive against their predators. Regeneration allows the salamander to escape their predators by losing an appendage, with the hope of preventing capture and subsequent consumption. Salamander regeneration holds so much value to the world and it’s surrounding life cycles. This overpowering ability is being overlooked, yet at the same time imagine how renowned it would be if we can link a gene that would aid with our regenerating gene. At a young age, we are all born with the ability to regenerate; we are able to regenerate our fingertips until the age of three…now try to apply that to future of regenerative therapy and medicine. Imagine how many benefits would be distributed amongst our cells, our organs, and the list goes on. The underlying process that goes with regeneration is the genetic materials; retinoic acid -(MSX1) and taxon specific proteins such
