cancer or Alzheimer’s. Thanks to an important discovery made only a century ago, the curability of these diseases, and other future diseases, is being challenged by a new cure all called stem cells. The term “stem cell” has been around for a quite some time, even though the actual understanding of these cells is relatively new. First used in 1868, by the biologist Ernst Haeckel, it was used to describe the extremely broad topic of egg fertilization (childrenshopsital.org). Now used in a variety…

Squamous Cell Carcinoma Squamous cell carcinoma is a common form of skin cancer. It begins in the squamous cells in the outer layer of the skin (epidermis). It occurs most often in parts of the body that are frequently exposed to the sun, such as the face, lips, neck, arms, legs, and hands. However, this condition can occur anywhere on the body, including the inside of the mouth, sites of long-term (chronic) scarring, and the anus. If treated soon enough, squamous cell carcinoma rarely spreads…

of Research with Stem Cells” by Susan Solomon “The Promise of Research with Stem Cells” by Susan Solomon is about the benefits of using stem cells for research in order to find the reasons of different types of diseases and their cure. She described how expensive drug research is and the potential loss that comes with it sometimes when it has a side effect. On the other hand, the research with stem cells will be so much better because everything will be tested on the cells before putting…

her “immortal cells” was the idea that doctors should be required to obtain informed consent from their patients before conducting any extensive research that could affect the patient. Aside from the HeLa case itself, another situation mentioned in the book was Mo versus Golde, a case where a doctor- David Golde- patented and profited off of the cells of one of his patients- John Moore. Doctor David Golde should have been prosecuted for taking and profiting off of John Moore’s cells without his…

Lab 4: Osmotic regulation of cell volume The eukaryotic organism requires homeostasis to maintain daily activities and life. Zooming into smaller units to make up an organism, cells also require homeostasis in order for the organisms to function. Understanding the different balance cells need to maintain will aid us in understanding how cells in organisms successfully maintain osmo-regulations. Eukaryotic cells have selective permeable membrane giving them the unique function of regulating…

Stem cells are cells that are found in almost all multicellular organisms. In 1908, a histologist, Maksimov, proposed stem cells. These cells have the ability to develop into many different cells that serve as an internal repair system in tissues. Stem cells are the objects in biomedical research and are differentiated from other cells. Embryonic stem cells are from the earliest stage of human embryo that develop into eggs by in-vitro fertilization. Embryonic stem cells are derived from the…

quadrillions of cells in the human body, there is on average 30 trillion red blood cells. There 's many qualities that make red blood cells different from the other cells. First of all, red blood cells are used to carry oxygen from the lungs to other parts ofthe body such as the tissue, and deposits the oxygen in there and brings back the carbon dioxide so it can be exhaled and thrown out of the human body. Secondary, there are a lot of things that we may not have ever heard about red blood…

like most cells, Stem Cells are unicellular, however they have two distinct properties that are completely different from other cells, shown through two unique qualities. They can replicate themselves continuously and they can grow into any of the body’s 220 different cell types. These two qualities makes Stem Cells promising tools in future medical research, which allows patients to receive needed cells or tissues, or have diseased cells or tissues replaced with healthy ones. Stem cells are…

Comprehensive Medical Report on Sickle Cell Anemia Where did sickle cell come from? Sickle cell disease is said to have originated in West Africa. Sickle Cell Anemia is a very serious disease. It is a genetic disorder, which is inherited, and is the result of mutated hemoglobin. When a person has sickle cell anemia, their red blood cell count is lower than that of a normal person with a healthy amount of red blood cells. When a person does not have enough healthy red blood cells in their body,…

NK-cells (natural killers) represent a heterogeneous lymphocytes population of innate immune system. They have a natural cytolytic activity, are capable of producing cytokines and chemokines and are involved in the antiviral and antitumor body control. In the quiescent state, an average diameter of NK-cell is about 8.7 microns, while in the moment of its activation it may increase its size up to 10-12 microns (Ferlazzo et al., 2004). This feature was the reason for the initial determination of…
