Download file to see previous pages Stem cells refer to undifferentiated cells that have the capacity to differentiate and form specialized types of cells; these cells also have the ability for self regeneration. The potential of stem cells to differentiate encompasses the ability to develop and form other cell types. For instance, a totipotent stem cell such as a fertilized egg can develop into cell types such as embryonic membranes. In addition, a pleuripotent stem cell can advance and develop into cell types, which may emanate from all three germinal layers. Self-regeneration entails how stem cells divide, leading to the production of other stem cells. The division takes place symmetrically during the early stages of development. This means that each cell undergoes division, resulting to daughter cells that have the same potential (Panno 1).
Later on, asymmetrical division takes place with one of the daughter cells produced during symmetrical division, leading to the production of a stem cell and another cell that has more differentiation. Stem cells tend to occur in most multi-cellular organisms. They have the ability to undergo mitotic cell division and renew themselves. As a result, they may differentiate into numerous specialized cell types Panno 10). There are two main sources of stem cells; these include embryos that may be formed during embryological development (embryonic stem cells) and adult tissue, which can also be referred as adult stem cells. Adult stem cells can also be referred as somatic stem cells; after the development of the embryo, they can be found all over the body. Embryonic stem cells emanate from a human embryo, which can be four or five days in the development phase known as a blastocyst Panno 12).
Cloning refers to the process whereby there is the production of multiple offspring that tend to be identical. It entails the asexual production of a copy that looks exactly like the original. For instance, cloning can be used in the production of ...Download file to see next pagesRead More

Stem Cell Therapy

...?Stem cells are potentially capable of developing into a various cell types found in the body that are only present during the early stages of life and the growth stage. These cells also serve as an internal repair system of some kind in many tissues. They divide continuously throughout the life of the human or animal through their life, as long as they are still alive. The division of stem cells yields to new cells that are potentially about to remain as a stem cell or a new cell type altogether. ( Segers, 2008)1 Stem cell therapy is a...

Photovoltaic cells

...? Photovoltaic Cells Solar energy, being a renewable source of energy, is a boon for those who live in isolated locations, particularly where grid power cannot reach. Van Geet home is an off-grid house that has received a special attention for its energy saving designs. Photovoltaic Cell is a heart of energy systems producing energy from sun. PV cells alone constitute almost 50 percent of the total cost of such energy system; therefore, all research is directed toward the reduction of its production cost. Though it is still a costly technology yet its cost per watt has reduced considerably in last few years. PV cells energy conversion efficiency has now crossed mark of 20...

NKT cells

...? Review of the Biology of NKT Cells Review of the Biology of NKT Cells Natural Killer T cells (NKT) form a unique lineage oflymphocytes that exhibit unique characteristics depending on the associated T-cell repertoires. Immunologists have described three types of NKT cells in their efforts to analyze the roles played by these cells in promoting immune system functions. Thefunction of these NKT cells is closely linked to the development of atopic diseases such as asthma and dermatitis. With the alarming increase of asthma and other allergic diseases in the developing world, there is need for developing effective strategies to combat the high prevalence. Immunologists have been striving to unearth the connection between NKT cells... and the...

Stem Cells

...RESEARCH REPORT SUMMARY OF INFORMATION Stem cell research originated at the of Toronto in 1960. Stem cells are basically the progenitorcells from which all the different organs and tissues or our bodies arise. These cells, on further differentiation and development, form, repair and regenerate all the tissues of our body. These cells are present in rich supply in the embryo, in which they differentiate along different lines to form the different organ systems. In the adult their role is to repair and replenish the tissues that are damaged by wear and tear. Methods to elucidate human stem cells did not emerge until 1998. Nowadays scientists are working with three types of stem cells: Embryonic stem cells Adult stem cells Induced... ...

Stem cells

...Client’s 8 February Science has technology has made significant progress in the last few years, what looked implausible a few years ago has become plausible today and what looks implausible today will become plausible tomorrow. Several major breakthroughs have been achieved in the last few years. Many new drugs have been invented to combat killer diseases and several lives have been saved because of these newly invented drugs. The invention of Stem cells has made life so much better. Significant progress in the field of stem cells was made by Dr. Ernest A. McCulloch and Dr. James E. They started working in unison in the 1960s and their research laid an ideal platform...

Embryonic cells

...Embryonic Cells The medical technological advancement in the field of embryonic stem cell research for therapeutic purposes has stirred up hot debate not only a national level but on a global level as well. I am very sure that not all of us will agree with the fact that the medical advancement using stem cells research is perhaps the zenith of medical research and a boon for human health. However, humans often tend to make the most important decisions and adopt wrong notions without gaining detailed knowledge about something. What are embryonic stem cells and stem cell technology? In...

Stem Cells

...Stem Cells Stem Cells I learned of your involvement in an accident with great sorrow, nevertheless, with the medical intervention you are going to receive, I am greatly optimistic that you are going to achieve a great magnitude of recovery. I have equally learnt that you are going to receive a trial of a stem cell therapy, and this is equally part of my motive for addressing this letter to you in an attempt to shed some light on stem cells, and their implication on the kind of therapy you are going to receive. It is thus interesting to inform you that this letter is going to take the form of a descriptive essay (Moore & Lemischka, 2006). Stem Cells are specialized and powerful cells found in the body. The stem cells are non... ...

Fuel Cells

...Fuel Cells Chemistry Fuel cells Introduction In science, a fuel cell is defined as a device that can convert chemical energy using oxidizing agents. Hydrogen acts as the basic fuel, although fuel cells require oxygen as well. The electricity produced through a chemical reaction does not involve combustion. Fuel cells require a continuous supply of oxygen and air for them to operate. In addition, for electricity to be produced, carbonate fuel cells produce hydrogen directly from a source of fuel. All fuel cells contain an anode, the positive electrode, a cathode-the negative electrode and an electrolyte-a liquid that...

Fuel cells

...Gas Turbine Engine Deterioration Number Introduction There has been increased focus on fuel cell technology inrecent years as a form of renewable energy. This interest has been significantly higher for fuel cells in comparison to the other potential forms of energy production due to a number of reasons. The fuel cell technology works on the basis of electromagnetic conversion of chemical energy into electrical energy. The process of conversion in separated into two electrochemical reactions (Larminie, Dicks, & McDonald, 2003). Every type of fuel cells is made up of two electrodes forming the anode and the cathode that work in satisfying the two electrochemical reactions....
