with a history of the autosomal recessive disease Sickle cell anaemia should have all embryos screened with Pre-Implantation Genetic Diagnosis technology (PGD). If tested positive‚ treatment should be made compulsory for the child at a young age and will be treated with stem cell gene therapy. This disease has no personal relevance to me‚ however‚ there is currently 90K people suffering from Sickle cell anaemia in the United States. Sickle cell anaemia is relevant to society because it greatly reduces

Bone Marrow Donor Angels Do you know what it is like to get the news that a nine year old boy in your family has leukemia and only has six months to live? When we got the news of Jacob’s Leukemia‚ my Aunt Sharon ran outside in the rain and started screaming and crying. She had always dreamed of seeing Jacob graduate from college and be at his wedding. Now what would you do if I told you that you could help save Jacob’s life or someone else’s life with a marrow donation which your body regenerates

Samantha Rogers & Sarah Grill July 6‚ 2015 Stem Cell Biology and Regenerative Medicine Analyzing the Effects of PZQ on Planarian Head Regeneration Abstract This paper focuses on the question of whether or not the drug PZQ (Praziquantel) has an effect on the double-headed formation of planarians. As the rest of the report will describe in more detail‚ we used multiple concentrations of PZQ reconstituted in 95% ethanol to observe its effects on planarians cut in a shape that promoted double headed

However‚ new biomedical technologies which have been introduced in the critical area of human life and the family have given rise to further questions‚ in particular in the field of research on human embryos‚ the use of stem cells for therapeutic purposes‚ as well as in other areas of experimental medicine. These new questions require answers. The pace of scientific developments in this area and the publicity they have received have raised expectations and concerns in large

GROWTH OF A RAPID CYCLING BRASSICA Hypothesis: The purpose of this experiment is to demonstrate the totipotency of cells‚ and how this enables them to take on new functions when it is required for them to do so; In the case of this experiment‚ the cells of the Brassica plant will have to adapt to form roots and new stem material etc‚ in order to grow. I hypothesise that this will be exactly what happens and the plants will grow as they normally would under natural circumstances and conditions

receptor in T cells isolated from HIV patients to protect these lymphocytes from infection with the virus have been initiated. Moreover‚ ZFNs have been successfully employed to knockout or correct disease-related genes in human stem cells‚ including hematopoietic precursor cells and induced pluripotent stem cells. Targeted genome engineering approaches in multipotent and pluripotent stem cells hold great promise for future strategies geared toward correcting inborn mutations for personalized cell replacement

Epidermis Cells Aim: To see if rhubarb changes when it is placed in solutions of different concentrations. Introduction: "Plasmolysis in Rhubarb Epidermis Cells" is an experiment to see whether or not rhubarb changed its cell structure when placed within different types or solutions. "A single layer of plant cell is placed on a micrscope slide and either distilled water or 5% NaCl solution is added to the cells. Osmosis will occur resulting in either turgid cells or plasmolysed cells." (www

“It was alright. How was school?” I hadn’t done any work that day‚ and the guilt seeped into my bones‚ threatening to pour out the truth in that I hadn’t done schoolwork for a few weeks. “It was good. I worked on an essay today‚ something about stem cell research.” The lie slid out easily. He nodded his head anyway‚ and I suppose he preferred to believe a lie than upset the truth. “Where’s your mom?” “Napping – she got home a few hours ago.” I followed him into his bedroom and looked to my mom’s

and desirable animal. In the article titled “Use of Assisted Reproductive Technologies for Livestock Development” the authors Chakravarthi and Balaji use reproductive cloning‚ which is the process on an entire organism being created from a single cell of a parent organism and having the exact same DNA‚ as a way to create a more enhanced population of livestock in a shorter period of time. When animals are reproduced in this way‚ desirable traits‚ like milk production and meat yield‚ can be selected
