In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions. Until recently, scientists primarily worked with two kinds of stem cells from animals and humans: The functions and characteristics of these cells will be explained in this document. Scientists discovered ways to derive embryonic stem cells from early mouse embryos more than 30 years ago, in The detailed study of the biology of mouse stem cells led to the discovery, in , of a method to derive stem cells from human embryos and grow the cells in the laboratory.
These cells are called human embryonic stem cells. The embryos used in these studies were created for reproductive purposes through in vitro fertilization procedures. When they were no longer needed for that purpose, they were donated for research with the informed consent of the donor. In , researchers made another breakthrough by identifying conditions that would allow some specialized adult cells to be "reprogrammed" genetically to assume a stem cell-like state.
This new type of stem cell, called induced pluripotent stem cells iPSCs , will be discussed in a later section of this document. Stem cells are important for living organisms for many reasons. In the 3- to 5-day-old embryo, called a blastocyst , the inner cells give rise to the entire body of the organism, including all of the many specialized cell types and organs such as the heart, lungs, skin, sperm, eggs and other tissues.
In some adult tissues, such as bone marrow, muscle, and brain, discrete populations of adult stem cells generate replacements for cells that are lost through normal wear and tear, injury, or disease.
Given their unique regenerative abilities, stem cells offer new potentials for treating diseases such as diabetes, and heart disease. However, much work remains to be done in the laboratory and the clinic to understand how to use these cells for cell-based therapies to treat disease, which is also referred to as regenerative or reparative medicine. Scientists are already using stem cells in the laboratory to screen new drugs and to develop model systems to study normal growth and identify the causes of birth defects.
They do not require the destruction of the human embryo in order to harvest the stem cells. These particular type of stem cells again are pluripotent and have all the same qualities and capabilities as embryonic stem cells but the complication is that these are much harder and much more painful to extract from the human body said Weiss e. They require a bone marrow transplant to acquire the stem cells as well as the vast experimentation with these new kinds of stem cells.
They have begun to test these findings on rats and mice in which they have found great success in regrowing the testicular, neural, mammary, and olfactory cells. Unfortunately for us, the biomedical engineers have not found a successful way to cure many diseases yet. But once the bridges the gaps they will be able to, and save many of lives 3. The future with stem cell research. Embryonic stem cells is the scientific communities cure for all the unjust flaws in the human body.
For scientists, it represents a revolutionary path to discovering the causes and cures for many more human deficiencies. Embryonic stem cells are pluripotent, that is, they have the unique ability to develop into any cell types in the human body.
There is no clear cut winner in this argument but both sides have valid cases. Today, I have discussed the basic arguments of religion, the stem cell industry, and the future with stem cell research. With this information about the battle of science vs religion I hope that you have better knowledge of the topic. Humans tend to be very argumentative, aggressive, and strong willed but this irrationality is only putting the lives of millions in jeopardy due to this quarrelsome mindset by the religious and scientific leaders throughout the many centuries.
The possibilities are endless, all that is needed is cooperation amongst all human beings; atheists, Catholics, Buddhists, Muslims, etc. An ethical solution has presented itself throughout all the fighting, lets take this discovery and put it to good use. Bryson In other words, lets help humans, help humans.
Let me help you. In the great debate of biomedical engineering, stem cell research has become a hot topic as the religious community has become outraged with the destruction of human life for medical experimentation We will write a custom essay sample on. Do Not Waste Your Time.
