The ethical issues that have been raised by studies reveal how the society needs to view stem cells in a way that respects the human dignity. Stem Cell Definition The body of a human being is made up of several different cells. Some of these cells include: bone cells, skin cells, muscle cells, and blood cells. These different body cells have specific shapes and each of them plays different roles in the human body. These cells can also be referred to as differentiated cells since they play several varied functions in the human body. In addition, these specialized cells can be characterized by their lifespan, which is a period of time within which they become old, stop dividing themselves and finally “die”. Moreover, when these cells divide themselves, they cause daughter cells that resemble their own type (Tremain, 2010). This further implies that in case of a skin cell, it can produce another skin cell, a muscle cell can produce another muscle cell; they are like the original parent cells. Human bodies are therefore made up of trillions of differentiated cells. Apart from the differentiated cells, the human body also has stem cells that are scarce. Unlike the differentiated cells, the stem cells are not specialized for certain functions and are, thus, called undifferentiated cells. These cells are immortal and they can divide themselves and continue growing as long they are kept in a suitable environment, such as in the laboratory as they receive the required nutrients. Stem cells in the other case can divide and cause...
Stem cells are the basic building blocks of the human body. They are more so vital to the human body since they can change and become different cell types. Scientists, moreover, claim that the stem cell research would enable them to learn more about reproduction, cell biology, and the stem cell knowledge would be vital in testing of drugs, and development. There are, thus, three types of stem cells: embryonic stem cells, adult stem cells, and foetal stem cells. The stem cells have been recognized in the animal and human tissues (Ikemoto, 2009). Although it is not possible to replace somebody’s parts such as a leg or finger, it is, however, imminent that the human body usually regenerates blood, skin, and other body tissues. Some past research has brought about some knowledge that somebody’s cells allow the human body tissues to regenerate. This was possible through the existence of stem cells in the body of human beings. Physicians would be able to repair damaged cells through the stem cells' ability to create the body specialized cell types (Tremain, 2010). One would, however, ask what stem cells are? Why would scientists want to research on stem cells and yet they bring about a lot of controversy? And what can be done to bring about ethics in destructive human research? This paper tries to answer these questions based on stem cell research. The scientists that are involved in stem cell research have often been surprised by the opposition they are receiving from the public concerning their work. ...Download file to see next pagesRead More

Stem Cells
Consequently, when a stem cell divides, it has the capacity of becoming a different type cell. For example, it can became a brain cell, muscle cell or remain as a stem cell. Stem cell is different from other cells in the

Reprogramming Normal and Cancerous Human Cells Lines into Human Induced Pluripotent Stem Cells
Using electroporation, it is possible to activate the natural reprogramming potential of living Xenopus laevis oocytes and pass it on to donor cells placed with eggs in one electroporation chamber. We demonstrated that co-electroporation at 150 v/cm / 25 µF of mature oocytes with ~105 cells/ml of suspension of various normal and cancerous human cell lines, such as bone marrow stromal cells, CD4+ T-lymphocytes, cervical carcinoma (HeLa) cells and breast adenocarcinoma (MCF-7) cells, reprograms donor cells into iPSc-like cells, which form colonies on irradiated MEF feeders.

Stem Cells Paper
Background The reconstruction of lost or damaged bones has continued to be a significant problem in the reconstruction surgery. Previously, bone reconstruction surgeons made use of artificial tissues to repair the damaged bones. However, artificial tissues have proved to be problematic to patients, which have encouraged surgeons to look for alternatives approaches.
