Stem cells are unspecialized; upon division they are capable of giving rise to a more specialized progenitor or to remain as a stem cell, proprieties called differentiation and self-renewal, respectively. During early development, a few of these cells are responsible for creating all tissues in a fully developed organism. In the adult tissues, they maintain homeostasis by replenishing cells lost in normal biologic process and injury. Due to their unique properties a lot of expectation and enthusiasm was build up around their possible utilization in the field of regenerative medicine. The intention was to employ stem cells in the unlimited production of healthy differentiated progeny, in order to replace cells lost by patients with degenerative diseases, such as Parkinson’s disease. Although simple in theory, this technique raised various questions about source, large-scale production, safety, delivery, rejection, the cell type to be transplant, cell behavior once in the patient and so forth (Pera, 2015).
There are a few sources of stem cells to be considered, including embryos and the adult tissue. The major difference between these cells is their potency, the range of differentiated cells they can generate. Human embryonic stem cells (hESC) are derived from the inner cells mass of the pre-implantation blastocyst stage. They are pluripotent, capable of differentiating into all cells originated from the three primary germ layers (endoderm, mesoderm and ectoderm). On the other hand, adult stem cells are usually multipotent, giving rise only to the major cells types present in their tissue of origin. Yet another source of pluripotent cells are the so-called induced pluripotent stem cells (iPSC), which are created by re-programming so...

... the number of cells necessary for transplant is very low and the eye easily to accessed and monitored.
Due to stem cells unique properties, they have a huge potential to be utilized in the treatment of regenerative diseases. Nevertheless, there still several unanswered question and aspects that need to be refined for stem cell-based therapy in clinical setting. So far the most prominent cell type utilized in regenerative medicine is the differentiated progeny of hESC, which is more easily obtained than other stem cells. The first clinical trial was performed with hESC-derived RPE for the treatment of macula regeneration. So far, no safety issues were observed and some recovery of the patients was noticed. Most of the success of this trial can be attributed to the particular characteristics of the eye, nevertheless a lot can be learned to be applied in future trials.

Stem Cells Essay

- Introduction Stem cells are a certain type of cells that are classified by their ability to differentiate into different tissues. They are also self- renewing cells. There are three different types of stem cells that have been discovered (Iwamori, Iwamori, & Matzuk M., 2012). The types are embryonic, adult, and induced pluripotent stem cells. Research is currently being done to analyze the potential medical benefits of stem cells. There are also many different ethical questions surrounding stem cells (Shahid & Irshad, 2012)....   [tags: tissue, ethics, embryonic, adult, pluripotent]

The Cells And Adult Stem Cells Essays

- Today, what I would like to talk about is stem cells, which is a kind of the most important cells because it is a foundation for the development and growth of other lots of different cell types. There are many other tissues they are working with internal repair system and they also can divide necessarily for supplement to other cells if they are still alive. But, the condition is different of stem cell, which has two major functions compare with other cell types, remaining a stem cell continually or transforming to other cells that have specialized functions like bone marrow cells, and they can divide and renew by themselves for a long time....   [tags: Stem cell, Cellular differentiation]

Essay on Stem Cell Research : Stem Cells

- Stem cell research has been around for many years. What are stem cells. They are the base cells of our bodies. Cells that make up our organs and tissues are the cells that come from stem cells after fertilization. Stem cells have the ability to replace cells that are lost and can repair injured tissues. They are made up of two characteristics which are their capacity to self-renew and differentiate. Self-new is when they the cell divide and create more stem cells. Differentiate is when the stem cells turn in more specialized cells that make up our tissues and organs....   [tags: Stem cell, Cellular differentiation, Stem cells]

Human Embryonic Stem cells and Induced Pluripotent Cells Essay

- Human Embryonic Stem cells and Induced Pluripotent Stem Cells are two modern methods of research; and treatment being aimed at the treatment of cancer, and many degenerative and genetic diseases. Stem cells are cells with the ability to develop into a cell of a different type, some types of stem cells are able to differentiate or change into a cell which is specific and functional to a specific tissue or organ system. This unique ability is what many scientists are trying to focus towards regeneration of different tissues, or the creation of new tissue to help cure, or treat diseases like cancer, multiple sclerosis, and alzheimer's....   [tags: stem cells, human embryonic, cells]

Different Types of Stem Cells Essay

- Stem cells have the ability to grow and multiply into many different cells in the early life of the body. Stem cells help to replace dead and or damaged cells in the human body. These stem cells are found inside the body, inside our organs and tissues such as in our skin and liver. Each stem cell helps its organ or tissue such as if the liver is damaged, the liver stem cells would repair the liver. There are four main types of stem cells: adult, fetal and embryonic. Each of these stem cells acts in a different way and have their own nature....   [tags: biology, cells, organs, tissues]
