Problems of Stem Cell Research Essay

Magnolia Abreu 10-30-2016 Bio 240 409A Prof. Gillen What are Kidney stones and how scientifics test the hypothesis that riding a roller coaster may help patient with small kidney stones to pass their stones more easily. Kidney stones are small stones made of mineral and acid salts that form hard mineral deposits inside the kidneys and can affect any part of the urinary tract. (Mayo Clinic) Last month a report showed that riding on a roller coaster may help patients that suffer from small…

About 60 to 80% of young adult–born neurons undergo a programmed cell death due to the required pro-apoptotic Bax gene. The transgenic mice used in this paper has TAM regulated recombinase CreER T2 expressed in it under the control of Nestin promoter fragment and a Bax conditional mouse. This allows Bax selectivity in the neuronal stem of the adult brain. When examining the adult hippocampal neurogenesis in mice with one Nestin CreER T2 (NCff) and…

energy, vomiting, and unexplained weight loss. To diagnose ALL, a doctor or oncologist will take tests on your bone marrow. These tests will allow a doctor to find out how many ALL cells are in your marrow to determine the best possible treatment plan. The types of treatments the doctor’s uses are: chemotherapy, stem cell transplantation, Ph-positive ALL therapy, and clinical trials that involve…

The aging population are living longer in some parts of the world, and most research that have been unraveled has been guided by the free radical theory of aging. The free radical theory has provided a hypothetical plan for advance scientific work to gain more knowledge on aging. There are more than three hundred theories that could be classified into three groups.: The genetic Mutation theories, the wear and tear theories, and the cellular waste accumulation theories. Which could be divided…

standard treatment of surgery, radiation, and chemotherapy. Quality treatment incorporates the transport of characteristics that drive the treatment to the tumor cells. Along these lines, it is essential to discover a vector that conveys a particular quality to tumor tissue productively and to characterize the kind of qualities that murder tumor cells generally…

into elephants, their closest living relatives. This process gives the offspring characteristics of both species, including more hair and longer tusks. Another method scientists are using is to cut DNA from the mammoth cells and place it into specific sequences of DNA in elephant cells, which has the same effect as the first method. Both approaches have been somewhat successful, but neither method has seen flawless results. Many of the offspring do not live for a long enough to be considered…

Dr. Hudspeth is the winner of many awards. The W. Alden Spencer Award was given to him in 1985 for “outstanding research contributions” from Colombia University. In 1991, he was awarded the K.S. Cole Award by the Biophysical Society for making ‘substantial contributions to the understanding of membrane biophysics” (Biophysical Society). Dr. Hudspeth has also won the Charles A Dana Award, the Talph W. Gererd Prize from the Society of Neuroscience, and the Guyot Prize. He is also a member of the…

(Griffioen & Molema, 2000). Endothelial cells which line the blood vessels are in direct contact with blood. Below the layer of endothelial cells, the pericytes (structural support cells) surround the blood vessels along with fibroblasts, smooth muscle cells, extracellular membrane and basement membrane (Griffioen & Molema, 2000). Endothelial cells play a role in many regulatory processes such as release of chemo-acctractants (cytokines and chemokines) that directs cells of the immune system…

hormones. Androgens such as oxymetholone can increase red blood cell counts(Dokal et al., 2011; Khincha et al., 2014). Granulocyte colony stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) can also be used to help increase the production of certain white blood cells (neutrophils)(Dokal et al., 2011). These treatments are only temporary, however(Dokal et al., 2011; Khincha et al., 2014). Hematopoietic stem cell transplantation can cure or ameliorate some of…

All organisms are made of billions of cells, so cells can work together so that, in order to happen, the cell must be able to work. The cell must be able to maintain the balance to be able to work. As a result, through advances in scientists such as Peter Agry and Rodrik McKinnon, we are able to know how their work is. Through them, we discovered everything the cell needs to work. Through them, we discovered everything the cell needs to work: channels, gates, and fuses. The first aqueduct was…
