Embryonic stem cell

lab. Work’s team noticed that the virus seemed to grow in skin cells. However, non-mammal skin cells had never been grown in a lab before. Skin is three dimensional, so the researchers took both tumor and healthy skin cells to replicate it. Turtle skin is also typically covered with everything from tiny bacteria to larger barnacles, so finding a sterile piece to grow in the lab is difficult. Eventually the skin cells were successfully grown in the laboratory. Researchers saw…

fascinating study of stem cells and tissue regenerations. The regeneration of the planarian may require the planarian to reshape its form by finding the right proportion to acquire the right shape and size of its body to form a functional, bilaterally symmetrical anatomy. The regeneration period can vary with different species, some may take as short as a week to fully regenerates its body proportion while other may take longer. The model organism, Dugesia, is composed of adult stem cells that…

Today I read the 2 articles required, The first article is “ Patenting Life” by Michael Crichton. The second article is “ Decoding the Use of Gene Patents” by John E. Calfee. The subject of both articles is Gene Patenting. They both discuss the pros and cons of gene patenting. Gene patenting has been a controversial subject since its beginnings. The two contrasting positions have been that the patent is harmful and the other is the patent is for the overall benefit on mankind. The first…

patients) or Trastuzumab (HER-2 positive patients). The IHC biomarker c-kit (CD117), which is used in the clinic to detect gastrointestinal stromal tumours (GISTs) (Debiec-Rychter et al., 2004), and p63, which is used to detect the presence of basal cells indicative of normal prostate glands (R. B. Shah, Zhou, LeBlanc, Snyder, & Rubin, 2002; Weinstein, Signoretti, & Loda, 2002), are the latest FDA approved single marker IHC-based assays which were approved almost a decade ago in 2004 and 2005,…

Blewitt text and the reading by Sylwester. Broderick and Blewitt open the chapter by explaining the intricate process of how the brain is formed and how it develops throughout gestation. Once the brain structure itself has formed in the womb, nerve cells called neurons begin to form (Broderick & Blewitt, 2010). The brain sends information to the rest of the body through neurotransmitters that are housed in terminals at the end of axons (Sylwester, 1995). Sylwester gave an interesting analogy…

From stem cell research to cryonics to artificial organs, mankind has gained immense knowledge.Considering today's circumstances with research done, the possibility of Frankenstein's monster being successful is much more…

When HeLa cells started to be sold, do you think Dr.Gey should have stepped in to assure that Henrietta Lacks’ family was compensated in some way? Do you think they should be compensated at all? Dr. Gey should have looked out for the Lacks family and let them know about the cells back in 1951. The lives of Henrietta’s children would have been greatly improved had they had that money. The Lacks family deserves compensation not only because Henrietta’s cells were taken without permission, but…

An author is expanding he or her ethos and logs in a scholar journal and popular article by quotation. The quotation is used in order to expand the knowledge of the paper and established a credible of a topic. According to Linton, Madigan and Johnson scientific paper stay away from using direct quotation for two reason “First the practice of rephrasing minimizes explicit attention to the language in which ideas are expressed and contributes to what George Dillon has called “the rhetoric of…

animal testing, the science world and society have always disagreed on many subjects. One of those controversial subjects that science and society still hasn't agreed on is Therapeutic Cloning. Therapeutic cloning is the practice of producing embryonic cells to replace or repair a damaged tissue or organ (Henry, 2010). Therapeutic cloning is a long and complicated process, which has also experienced many failures. The process…

This form of communication can be used to directly resolve a situation between members of staff regarding a sample or inform a member of staff about information they have acquired. For example, if a stained bone marrow smear is not adequate for a cell morphology study, the consultant can directly ask me for a restrain of the same bone marrow aspirate smear or the staining of a completely new smear from the same patient. While vocal dissemination of information can be easy to express, it also can…
