Embryonic development is the changes an embryo undergoes as it grows toward a developed organism. In early embryonic development, the first stage begins with fertilization, when the female egg fuses with the male sperm to create a zygote (Biology.OpenStax.1753). After a zygote is formed, cleavage (unusually large cell) converts the zygote to a multicellular organism (embryo) by rapidly dividing a single cell (each the same size) to form a hollow ball of cells, called a blastula. The next stage…

Umbilical Hernias occur when the umbilical cord passes through the small opening in the babies abdominal muscles. The muscles usually close after birth. If the muscles don't join together and close, the abdominal wall becomes weaker and may cause an umbilical hernia at birth or later in life. An umbilical hernia can also happen in adults, mostly in women. Most hernias close on their own by age one on there own. Hernias that are much larger need surgical repair. About 90 percents of umbilical…

Embryonic Stem Cell Research: The Okay Way to Kill a Baby Today, society’s ethics have gone almost completely away. Society justifies that one life lost is okay to lose if it ends up saving thousands. Embryonic stem cell research is exactly that justification. Stem cell research is taking one type of cell and trying to coax it into a different type of cell. Embryonic stem cell research is taking an embryo and coaxing it into becoming a differing type of cell and destroying its chances at…

Earlier this month two people from Biogen, a firm that creates medical drugs to help treat various medical conditions, came to discuss the medical and business sides of creating a new treatment called Spinraza. Spinraza is a drug that is used to treat Spinal Muscular Atrophy(SMA) which is a rare genetic linked condition that causes a loss of nerve cells inside of the spinal cord. This loss of nerve cells causes a loss of motor function and can often be lethal, especially when the age of onset…

“Embryonic stem cell research will prolong life, improve life and give hope for life to millions of people.” This quote by Jim Ramstad is about the benefits of Embryonic Stem Cell Research. “Stem cells provide an opportunity to investigate the mechanisms that regulate embryonic development, cellular differentiation, and organ maintenance” (Ramalho-Santos and Willenbring 35-38). Embryonic stem cell research has been around for many years. It has proven to be very beneficial to the medical world,…

Over the course of many centuries, scientific study and research has seen significant advancements, especially when it comes to the study of the human body. One of the major developments is embryonic stem cell research which involves the use of cells from early stage embryos. These cells are important because they have yet to mature and therefore are able to evolve into any type of cell found in the human body. Through the use of embryonic stem cell research, scientists may be enabled to learn…

Dear minister of health, Incase you haven’t known (which you might have, unless it was buried under a big pile of letters), stem cells are the new medical “it thing”. Stem cells are undifferentiated cells that can differentiate/change into specialized cells and can divide to produce more stem cells. Even though they are unspecialized, stem cells can develop into specialized cells. Stem cells can make up to 220 different cells in the human body, they also have the capability to self renew.…

I’m sure some of you have had a friend or family member who has passed as the result of an incurable disease. Stem cells have the remarkable medical potential to cure a myriad of degenerative diseases. According to Rosemary Tong, a biomedical ethicist, stem cell research has the potential to develop treatment for 58 million Americans with heart disease, 82 million with cancer, 4 million with Alzheimer’s disease, along with many others. A stem cell is an undifferentiated cell that is capable of…

When multi-cellular organisms develop, cells must differentiate to form specialised cells, which have a diverse range of functions, these then give the organism the necessary assistance to survive and eventually live. A stem cell is a cell which is undifferentiated and not yet specialised, although it has to capability to form or configure itself into any other type of cell. Fertilised embryos are called zygotes which then produce pluripotent embryonic stem cells, a prerequisite to the survival…

Embryonic Stem Cell Research Samantha Sigman November 10th, 2014 Genetics Metropolitan Community College Typically, someone or something is special because of the uniqueness it fosters. A liver cell is special because its function is to preform as a filter or for the use of metabolism. Stem cells are so special because they have unbelievable potential in the world of genetics because they are not specifically special. According to Suzanne Holland, Karen Lebacqz and Laurie Zoloth in The…
