Stem Cells Essay

Tissue specific stem cells can create different cells for different organs and are obtained from different organs and tissues. Embryonic stem cells can increase every cell type in an adult body and are obtained from the blastocyst, a ball of cells formed a couple of days after an egg cell is fertilized. Mesenchymal stem cells are typically obtained from bone marrow and can produce bone and fat cells. Induced pluripotent stem cells are made in a science lab by changing tissue specific cells into embryonic cells and they help scientists research normal development.

For as long as humans exist, optimal health continues to remain vital for a productive life. As new medical discoveries increase through generations, humans become healthier, therefore, their life expectancy rises. Stem cell research, a relatively new field, investigates to improve and lengthen human life. The possibility of stem cells to develop prospering health makes them beneficial to the human race.

There are a lot of potential uses of stem cells, but there are obstacles that we need to go through first. Stem cells can be used to test new drugs that scientists make. We could generate healthy heart muscle cells with stem cells. Injected cells could repair things in the body by secreting growth factors. Before scientists start

In the past two decades, many technological and scientific advances have been made in order to make life easier for many people who suffer from cancer, disease and sickness. Among these advances there is something revolutionary called stem cells. Stem cells can help restore and regenerate almost all parts of the human body such as the heart, kidney, liver, and many other organs. Although stem cells offer a lot, there are many views against and for stem cells, and among these views lies the debate of whether stem cells should be legalized or not (NIH 2). Stem cells offer exciting new opportunities in the field of science such as regenerating human body parts, but many people are still debating whether or not the use of stem cells is

Because of stem cells regenerative qualities, many scientists hypothesize that eventually we can use stem cells on a large scale to assist us to regenerate damaged tissue within the body especially when transitioning organ donations, or prosthetics into an individual, ultimately making it a safer practice.

Scientists need the opportunity for research and they have researched that stem cells can do a lot of things such as having the potential to treat many diseases. (Devitt 14)

Stem cell research can be used in a multitude of way in which the main once being to treat disease. Scientists can use stem cells as a way of monitoring and learning about how some organisms can develop. Because of its ability to renew themselves, stem cells can be used to help treat and cure disease. They can also be used to study some diseases and further advancements in new medical

Until now there has not been a way to create these cells without destroying embryos.

As long humans have existed, having good health continues to remain crucial for a longer lasting life. As scientists find new medical discoveries throughout time, humans get healthier and their life expectancy goes up. Stem cell research is a new type of field of research, its goal is to improve and

Generation of different cell types present in blood is called haematopoiesis. Main sites for producing bone marrow are found in liver of the foetus and bone marrow in adults. There are different groups of cells involved in cell differentiation, one being pluripotent long term hematopoietic stem cells (LT-HSCs) which form adult stem cell population in bone marrow, are able to self-renew and by being multipotent, they are able to develop into many types of cell type but show less variation than pluripotent cells. Pluripotent cells arise during first stages of human embryo development, and are able to differentiate to all cell types that make up the body, such as embryonic stem cells migrating and forming different tissues on different sites of the body during embryonic growth. Short term hematopoietic stem cells (ST-HSCs) produce progenitors, which are able to differentiate into burst-forming units or colony-forming units where mature cell types such as erythrocytes are

At the end of the day people will have different views and perceptions on whether or not stem cell research should be continued. Stems cells have already contributed positively to modern medicine and with a few more years, stem cells will be the focal point of all medical

The proerythroblast is a large cell (12-20 μm) with a dark blue cytoplasm and a large nucleus; the chromatin is not condensed in this stage and contains one or more prominent nucleoli (Higgs and Wood 2011). The cytoplasm contains ribosomes, centrioles, a Golgi apparatus, few mitochondria and endoplasmic reticulums. These cells divide into smaller (10-16 μm) basophilic erythroblasts which also have dark blue cytoplasm and a large nucleus but the chromatin is started to condense in this stage of maturation which can be observed near the nuclear membrane. These cells then divide into polychromatic erythroblasts (10-12 μm), which are known for its pink cytoplasm and condensed nuclei. Orthochromatic erythroblasts are non-dividing cells with completely condensed pyknotic nuclei. Reticulocytes are easily recognized by its specific enucleating or nonnucleated

Stem cell research can further develop therapy for those in need. Stem cells are undifferentiated cells that are able to develop into any type of cell in the body, since they are able to do so they are one of the major factors in healing ourselves. Despite the hard work stem cells are able to do, people suffering from a major disease may not produce enough cells to fully heal and could look into stem cell therapy to get extra cells to help them heal completely. The therapy is done by transplantations, one is called nuclear transfer it is done by taking the patient's DNA of a cell and transferring it to an egg cell then the egg is placed in a culture dish and when the process is done the cells are re-introduced into the patient and are able to assist in the healing process. Someday using the therapies could possibly create

There are many reasons on which stem cell research should be continued to help possibly cure many diseases. Stem cells are a type of cell unlike most other cells. These cells differ from most cell in two ways. Stem cells are known as unspecialized cells capable of renewing themselves through cell division. Secondly, under certain physiologic or experimental conditions, they can be introduced to become tissue and or organ-specific cells with special functions. Stem cells are known to be a replacement for cells that have gone through normal wear and tear such as injuries or diseases. With this type of cell being able to replace other cells when old cells are destroyed or ruined. With their unique ability to regenerate they can be used to treat certain diseases such as heart disease and diabetes. This could also be used to treat certain types of

Stem cell research has become an important part of medical research in the past few years. Embryonic stem cell research is controversial because of the blurred lines in the moral viewpoints of many people. These embryonic stem cells are pure and are easily manipulated to fit any type of cell needed. This is useful in the testing of new drugs and treatments of permanent or incurable diseases such as ALS and MS. Adult stem cells are also useful in research, but they are already specialized which makes them only useful for the type of cell they come from.
