Planarian Regeneration Mechanism Subject to Different Cut-Types Introduction: Planarian are flatworms which are common in aqueous regions all across the world. They are often used as models in the study of biomedical and biotech sciences, due to their ability to regenerate. Planarian have such advanced regenerative properties that over 1/279th of the animal can completely regenerate (Handberg et al., 2007). They have powerful regenerative capabilities because they have an abundance of…

I personally believe that embryonic stem cell research is an important investment for the future. Stem cells are cells that are able to develop into different types of cells. Stems cells have the potential to be used to cure many diseases. There are also other uses for stem cells like organ repairs. Even though they would be so beneficial, there is an ethical debate. I believe that it is ethical and that it is something that should be done. There is a huge debate over the ethics of stem cell…

Many people disagree with stem cell research. Their biggest reason for this position is the embryonic stem cells would come from aborted fetuses. Some people feel that abortion is unethical and that stem cells obtained by breaking open and killing the embryo is morally wrong. They see it as murder and feel that we are a nation that places too little value on human life. They believe this goes against what they are taught through their religion and that destroying an embryo for the stem cells in…

Background and need: During embryo development many factors can determine the future outcome and growth of developing embryo. These factors, whether genetic or environmental, will influence the cells within the embryo and could result in a lasting developmental abnormality, such as unwanted apoptosis. Ethanol, a known teratogen, is one such unorthodox environmental factor that if present will have an effect on the embryo’s development; namely defects in the cardiovascular system, structural…

Scientists have discovered how to create life from dead babies. The very first successful test tube baby was in the 1970 and has been advancing since, but has been made illegal because of religious morals. stem cell research, though ruled unethical and against humanity’s morals has still been done in secret for many decades. .Planned parenthood has been influencing parents of aborted embryos and young women with healthy eggs, to donate the dead embryos and egg cells to science for stem cell…

Stem cells have become one of the most prominent fields of research within the medical industry, since the 20th century in the modern scientific world. A stem cell is an immature biological cell that has the potential to transform into differentiated specialised cells to perform various functions and features within a body. These cells are found within various multi – cellular organisms, and have the potential to reproduce by the process of mitosis to produce more stem cells. In mammals, these…

Benjamin Harouni Sigurdsen BISC 120 Lab November 2014 Modeling the regeneration of Gugesia dorotocephala: The window into human regeneration Introduction: The field of regenerative medicine aspires to control the ability to regulate the growth of organs and appendages. In order to control the growth and help those who suffer from injuries, defects and degenerative diseases, scientists must learn about the natural molecular tools that animals use to repair damage to their bodies. The medical…

Stem Cells Stem Cells are an unspecialized type of cell that can change into many different types of cells in early stages of life. In certain tissues these cells act as a type of internal repair system, which divide with almost no limit and repair and replace old or replenish other cells if the person or animal is alive. When stem cells divide they have the chance to become a different type of cell with a more specialized function or stay a stem cell¹. Stem cells are important because they can…

Kirk Stewart English 10-10 Buck Tilton Annotated Bibliography Brown, N. (2006). Blood Ties: Banking the Stem Cell Promise.. Technology Analysis & Strategic Management, 18 (3/4), 313-327. The author focuses on umbilical cord blood stem cells in his article. This article is about the future, and what soon possibilities there are stem cell research and cord blood. Also it includes some emotional aspects of saving cord blood. It talks about the actions taken that parents prepare for with troubled…

The promise and limitations of using Stem Cell Therapy to treat spinal cord injury. First Name Last Name College Name Introduction Stem cell therapy, otherwise called regenerative drug, is the utilization of undeveloped cells or their subordinates to advance the reparative reaction of sick, useless or harmed tissues. Scientists search for foundational microorganisms in a research facility where these undifferentiated organ-isms are controlled to represent considerable authority in particular…
