Engineers at Duke University just proved dead heart muscles in human patients can still be repaired. The fully functioning artificial human heart muscle developed was big enough to patch over damage usually seen in heart attack patients. Ilia Shadrin, a biomedical engineering doctoral student at Duke University, said the patch is a way to replace lost muscle with tissue made outside the body. Current therapies target to reduce the symptoms from the damage caused by the attack to the heart. However, they did not provide approaches to replace the muscle because once lost, it is dead, and it will not grow back on its own. Replacing the lost muscle A scar tissue that could no longer transmit electrical signals or contract often replaces the†¦show more content†¦The Duke University team’s creation is the first human heart patch to meet the two criteria. Nenad Bursac, a professor of biomedical engineering at Duke, said that creating individual cardiac muscle cells is quite common, but the creators should have focused on growing miniature tissues for drug development. It needed a lot of engineering ingenuity to scale it up to the size made by the team on the first time it has been done. Human pluripotent stem cells The cells for the heart patch, grown from human pluripotent stem cells, can become any type of cell in the body. By using different lines of human stem cells, the Duke University team has successfully made patches, including those taken from embryos and those artificially forced or induced into the pluripotent state. There are various types of heart cells grown from the stem cells, like cells for muscle contraction, those that provide the structural framework for heart tissue, and those that form blood vessels. The Duke University researchers placed the cells at specific ratios into a substance similar to jelly where it self-organized and grew into functioning tissue. To find the right combination of cells, nutrients, support structures, culture conditions, and growth factors to grow large, fully functional patches of human heart tissue, it took the team years of work. They sized up and engineered from scratch every container and procedure from scratch.

This technology offers hope to millions who are victims of a multitude of diseases and disorders. It can be used to regrow limbs, create organs, attack genetic diseases, treat malfunctioning bladders, etc. However, this same technology is also one of the most controversial debates in science today.

Research in the use of stem cells holds limitless possibilities in the medical field. Stem cells are the cells in our bodies that are in their primitive form. These cells have not yet become the type of cell they are destined to be, whether it be nervous tissue or another. However, even though stem cell research is a great new field, its progress is being limited by moral concerns and ethical questions. In order to let medicine reach its full potential, stem cell research should be legalizedRead MoreStem Cells Essay1530 Words   |  7 Pages Stem cells are used every day throughout the United States to help cure diseases and save lives. Stem cells can also be used to study labor defects so that future birth deficiencies can be prevented or reversed. Although as a college student starting a family may not be on your mind yet, it is always beneficial to educate yourself on current trends and new discoveries in stem cell research.

Without a doubt, hair is a an overlooked vital aspect of daily life. At birth, hair follicles are developed and undergo a total of three phases: anagen, catagenRead MoreStem Cell Essay939 Words   |  4 PagesInduced Pluripotent Stem Cells and their use in Cardiac Regeneration Introduction Myocardial infarction (MI) is the leading causes of mortality and morbidity in the world. Ischemic heart disease, where the oxygen supply to the myocardium is restricted, is a common cause of an MI. Myocardial injury results in loss of cardiomyocytes (cardiac muscle cells) due to apoptosis, and the development of necrotic myocardium, eventually leading to heart failure. The formation of the necrotic myocardium causesRead MoreStem Cell Essay1061 Words   |  5 Pagestreated with the use of embryonic stem cells. Embryonic stem cells are cells derived from the undifferentiated inner mass cells of human embryo. In simpler terms, these cells have the ability of developing into any of the two hundred different cell types in our bodies. Unlike most of the cells in our bodies, such as heart cells or skin cells, which conduct a specific function, a stem cell does not have a specific function until it is specialized (Hogan). A stem cell that is becoming specialized willRead More Stem Cells Es say1128 Words   |  5 PagesEmbryonic Stem Cells â€Å"Embryonic stem cells...are in effect, a human self-repair kit,† (Christopher Reeve, activist – Larry King show).

The authors of this article used this opportunity and found out that pleural effusions were great opportunities to be able to study metastasis and for isolating stem cells. The doctors basically isolated the cancer stem cells(csc) and the non cancer stem cells(non-csc) and were able to derive how fast these stem cells were able to form.

Although they have a limited capacity to differentiate and they are compatible with adult tissue, you can only obtain a small amount of cells. An alternative would be obtaining stem cell from the umbilical cord, given the fact that are easily to obtain, they are compatible with other body tissue , they may have a limited capacity to differentiate but they are not a treat to the child life. Both these option offer a small amount
