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…

There are many people out there who have said that stem cell research is a crucial part to moving up in medical technologies. Stem cell research can help doctors unlock different and more helpful forms of medicines that can impact many different illnesses. But then on the other hand, there are people who see stem cell research as a negative and basically a form of abortion. Now abortion is an issue all on its own but when stem cell research, which is supposed to be beneficial to society, is…

Introduction: Planarians are free-living aquatic flatworms that posses remarkable regeneration abilities in addition to its distinct negative phototaxis behavior. A wealth of research studies has thoroughly examined its photophobic behavior under different wave frequencies and light conditions. Planarian are highly sensitive to white light and wavelengths of high frequencies, blue-green range ( Paskin TR, 2014). Two basic pigment-cup eyes situated in the head region govern its photophobic…

1.2. Brain Development Brain development starts at the embryonic period, more specifically at the fifth week of pregnancy. Figure 1.1 illustrates the timeline of pregnancy by weeks and months of GA (16). In the first months of pregnancy and before birth, the brain experiences the most development and changes in shape, size and structure (17, 18). Most significantly, changes occur in the size of the brain and in the cortical folding. Growth continues rapidly until the brain is two to three years…

EMBRYONIC STEM CELLS What are stem cells? Stem cells are the body's raw materials. Cells from which all other cells with specialized functions are generated they are also called daughter cells. They either become new stem cells or become specialized cells with a more specific function, such as blood cells, brain cells, heart muscle or bone. Embryonic stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. They can…
