There are many people out there who have said that stem cell research is a crucial part to moving up in medical technologies. Stem cell research can help doctors unlock different and more helpful forms of medicines that can impact many different illnesses. But then on the other hand, there are people who see stem cell research as a negative and basically a form of abortion. Now abortion is an issue all on its own but when stem cell research, which is supposed to be beneficial to society, is…

Introduction: Planarians are free-living aquatic flatworms that posses remarkable regeneration abilities in addition to its distinct negative phototaxis behavior. A wealth of research studies has thoroughly examined its photophobic behavior under different wave frequencies and light conditions. Planarian are highly sensitive to white light and wavelengths of high frequencies, blue-green range ( Paskin TR, 2014). Two basic pigment-cup eyes situated in the head region govern its photophobic…

1.2. Brain Development Brain development starts at the embryonic period, more specifically at the fifth week of pregnancy. Figure 1.1 illustrates the timeline of pregnancy by weeks and months of GA (16). In the first months of pregnancy and before birth, the brain experiences the most development and changes in shape, size and structure (17, 18). Most significantly, changes occur in the size of the brain and in the cortical folding. Growth continues rapidly until the brain is two to three years…

EMBRYONIC STEM CELLS What are stem cells? Stem cells are the body's raw materials. Cells from which all other cells with specialized functions are generated they are also called daughter cells. They either become new stem cells or become specialized cells with a more specific function, such as blood cells, brain cells, heart muscle or bone. Embryonic stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. They can…

diseases and the realisation that I could better the lives of many whilst working in this field. The transition from GCSE to A-level not only ignited my passion but made me appreciate the complexity yet fascinating spectrum that biology has to offer. Through studying biology at A-level, I have developed my analytical skills as a result of the extensive number of practices I have taken part in allowing me to critically analyse,…

Can you imagine a world without disease, a world where you can have any trait of your child, changed to what you want, or even reverse the aging process by years? Well, with your help it can all be possible by using Stem Cell Research and some genetics as needed. Stem Cell Research ,originally discovered in mice embryos in 1981 and later starting on human embryos and growing cells in labs in 1998, is a controversy having to do with research involving the development, use, and destruction of…

Cells are the BASIC function of life on Earth. They are the fundamental unit of all living things. The cell is the smallest structure in the human body and has all the properties of be alive and being it 's own living thing and stem cells are the direct result of cells being their own living thing. The stem cell is stated to be “unspecialized cells that are thought to be able to reproduce themselves indefinitely and, under the right conditions, to develop into mature cells, e.g., nerve, skin,…

A cell is a very basic structural and functional unit of life. A human body is considered multicellular because the body consists of trillions of cells. Cells have many different functions throughout the body, and they ‘stem’ from simpler cells that do not yet have a specific function. These cells are known as stem cells. This basically means these cells do not have a specific job in body yet, but have the potential to become any cell in the body. Stem Cell research has been around for decades,…

Stem cell research. Those three little words may seem so simple, but the mixed reactions and controversial propaganda that surround the topic are staggeringly diverse. Stem cells are very unique cells that have the ability to morph into any of the types of cells found in our bodies (Newton 3). Blood, heart, nerve, and skin are all types of cells that stem cells have the potential to turn into. Due to this, stem cells could quite easily cause revolutionary breakthroughs in the medical scene,…

to the attainment of cancer treatment. Stem cells are found in many diverse somatic tissues and are important contributors in their formation. Cells that descend from stem cells are organized where the stem cell resides at beginning of the developmental pathway. Stem cells have three distinguishing properties: self-renewal, the capability to develop into numerous lineages, and the potential to proliferate extensively (Jordan, et al. 2006). These three properties are what make stem cells so…
