Regenerative Medicine and the PCR Technique
By Ben Wooddell
Science is continuously evolving. Research into new and exciting fields reveals exciting new information on a daily basis. Since the very beginnings of science, science has always been helping mankind live longer and healthier lives. Every day scientists are still discovering new things, and sometimes these discoveries require doing things that stretch the boundaries of animal and human ethics, all for the greater good.
Since the ancient times humans have noticed and been amazed that some organs and organisms could appear to regenerate. As scientific principles became more know, interest increased. In 1712, a French scientist named René-Antoine did one of the first studies on the science

The first one is called rejuvenation and is the process by which your body heals itself. Cells in the body that scientists thought could never divide again, which includes special cells like the nerves, lungs and heart, have been shown to actually re-divide in some ways. This gives the organ the ability to self-heal at times, and scientists are studying ways to enhance the body’s self-healing process. The second way regenerative medicine works is by replacement. This involves replacing damaged organs using healthy, living cells, tissue or organs from a donor (which can be living or dead). Most people know this process as organ transplant, and even though it is slow, it is very effective and has saved many lives. So scientists want to find ways to expand opportunities for viable transplants by raising awareness of the value of organ donation. The last way regenerative medicine works is through a process called regeneration. This involves growing or putting live cells into a person so that the cell will divide and repair or re-grow tissue or even whole organs, on their own. An example of this is bone marrow transplants using stem cells, and involves cell-based therapy or the use of growth …show more content…
Harvesting stem cells involves taking new stem cells from human embryos, which unfortunately leads to the embryo’s destruction. The incredible value of embryonic stems cells is their versatility – they have the ability to become any one of over 200 cell types in the human body and their use in repairing or regenerating tissue is incredible. The PCR method which is short for polymerase chain reaction. this is a method which is used to analyze a small parts of DNA (or RNA). PCR is used to replicate selected sections of DNA or RNA. Before the PCR method scientists had to use bigger sections of DNA and RNA with two vectors to replicate, it would also take weeks to work. But now, with PCR method done in test tubes, it takes only a few hours for it to work. PCR is highly efficient in that untold numbers of copies can be made of the
However, many find this research unethical because of the method of collecting stem cells. Like Victor Frankenstein’s experiment,
PCR, especially with the use of stem-loop primers avoids obtaining cDNA from non-specific targets, producing a more reliable result whereas Northern procedure is, in general, less sensitive. PCR also requires very
Embryonic stem cells are the cells which potentially provide life to a blastocyst and lead to the creation of a fetus, or baby. Recently there have been many experiments conducted to extract embryonic stem cells from the blastocyst. With this new research, has also come a huge controversy. Although embryonic stem cell research is practiced with good intents and is designed to find cures for people already suffering or living a limited lifestyle due to health disabilities, what is not always mentioned is that another human’s life is being destroyed in the process. These innocent babies, whether it be considered legal or not, are being plucked from their mother’s womb to be used for nothing more than a science experiment.
As science becomes more advanced, research and testing of ways to heal the human body often leads to controversy over the moral and ethical dilemmas. The controversy over embryonic stem cell research has let to arguments over the funding of such research. Opponents to the research claim embryos are human lives and harvesting stem cells from them destroys the embryo thus kills a human life (SAUNDERS). Proponents argue the tremendous advantages to human health using embryonic stem cells that cannot be realized elsewhere (HUTTO). Dr. James Till and Dr. Ernest McCulloch discovered stem cells in mice in 1981.
On February 8, 1951 something incredible to the medical world was discovered, the HeLa cell. It was taken from Henrietta Lacks a patient who had a large tumor and shortly died of cancer after the finding of the large mass in her stomach. Yet, prior to her death on that day of February her physician without her consent took her cervical tissue and gave it to the researching finding that it kept doubling and growing in size making it ‘immortal’. Never had such a significant and powerful cells had been found before. The tissue has been used to stop diseases, HIV/AIDS, understand cancer, these cells have even been through space to see if it was safe for humans.
By having more and more treatments, whether risky, life shortening or prolonged pain, doctors and scientist will soon be able to find proper treatments that bring life back
This advanced technology has caused the development of treatments that can intervene in the dying process and prolong life. “They are reshaping the circumstances of natural death and sustaining human lives” (Karnik & Kanekar, 2016). However, even though these advancements exist, it does not mean the patients will recover. It is
Stem cells have the potential to cure specific diseases such as Parkinson 's, Alzheimer 's, Diabetes, and Cancer. A few years ago, you could only get stem cell transplants from specific doctors, But as of 2015 there are 170 clinics that can do the procedure. The way that they implant the stem cells into the patient 's body is by putting the cells straight into the bloodstream or by inserting the cells into the patient 's bone marrow. They extract all of the stem cells that they need and then they take out the patient 's dead stem cells and put in the donor 's healthy stem cells.
Regenerative prescription is a quickly advancing field which produces an abundance of unique and imaginative exploration. As the European Society of Human Reproduction and Embryology (ESHRE) inspires prepared to welcome another open access diary to its prestigious family, we meet the Editor-in-Chief, Professor Siladitya Bhattacharya, to discover how he sees the field creating later on, and what he has in store for Human Reproduction Open (HR Open). How would you see this field creating later on?
Regenerative medicine has a cure to failing or damage tissues. Stem cell increase years to human life, cure disorder and it also includes make one seems juvenile. As a result this gives leisure to the opening of stem cell clinics to the public in the Philippines. Cellular Therapeutics Center of Makati
Having stem cells renew and duplicate each other give scientist an opportunity to study the process of how it’s done. Knowing that, they’d have a better understanding on how proliferating (expansion of cells) is done right or done wrong, if done wrong it can often leads to
Tissue engineering and regenerative medicine are an interdisciplinary field that aims to maintain, repair or improve tissue functions that are defective or lost by Disease, injury and trauma, either by developing biological substitutes or by reconstructing tissues. Tissue autografting and allografting are commonly approaches that have used for replacing damaged or diseased tissue. Nevertheless, these approaches have faced with several drawbacks. Tissue engineering involves three key factors: scaffold, signaling molecules and cell culture. The development of scaffolds are the main areas of biomaterials research, and they play a pivotal role in tissue regeneration and repair.
How would you like to have another you? No, not an identical twin but another person who is actually 100% you? Would the idea fill you with delight or horror? You might be confused
Fix or replace damaged tissue; biology has always been the main concern for scientists. Today, the most important instrument for tissue engineering scientists to produce replacement tissues and implants to repair or replace damaged tissue. Tissue engineering is generating a new field of study in which the principles of engineering and biology to correct the damaged tissue, uses and can renewal, operation and maintenance of tissue healing. In order to use an ideal scaffold Tissue engineering should have features such as non-toxic Cell and tissue properties to be fit.
Stem cell therapies have the potential to be able to regenerate all of the tissues in the human body and along with gene therapy could be the most powerful tools in medicine with the potential to treat a
