Robert FreterUMUC Biology 103Paper: Biology and Technology in the Real World19 October 2014Dear Friend,I am so sorry to hear about your car accident. After doing a fair amount of research about spinal injury I started to grasp how complicated the area around the spinal cord is. It amazed me that the spinal cord has so many components to include neural cells and glia as well as nerve pathways in the cord alone, not to mention the complexity of the spinal column. I know it has been a while since you have study the human body but I overheard doctors offered some stem cell therapy to you so I wanted to enlighten you on the topic.There are two major forms of stem cells: Embryonic stem cells and Somatic stem cells. Embryonic stem cells are cells that are derived from embryos and are formed from eggs that are fertilized in a laboratory. Somatic, or adult stem cells are found in various parts of the body. These cells are also given variant names based on their origin of location. For example: Hematopoietic stem cells form all types of blood cells, bone marrow stromal stem cells form bones and cartilage components. Adult stem cells are less researched and normally regenerate when there is a need, injury or disease to replace existing cells in their surrounding tissue. These adult stem cells are differentiated and are able to form the type of cells surrounding it. Transdifferentiation is the ability of the stem cells to form different cell types. This is key to manipulating cells to change into what is needed to maintain a human fighting a disease, for example.The key difference in embryonic stem cells from all other cells is their ability to change type when they are splitting. Stem cells can take the form of muscle cells, brain cells and many other cells instead of forming more stem cells. Stem cells also have the ability to proliferate (replicate many times). As long as the stem cells do not change into a different form of cell they are capable of reproducing millions of times. Because they have the capability to reproduce many times and are unspecialized they have an incredible potential to replace cells humans are using do to cancer and disease. "For example, a blood-forming adult stem cell in the bone marrow normally gives rise to the many types of blood cells." (NIH 2009) Although they are able to change into specialized cells there is a lot of debate on what type of cells they will transform into. Studies have shown cases where the stem cells change into a completely different cell type than what it is surrounded by. Stem cells can be grown in a laboratory but the process is incredibly delicate. The cells must remain at certain intervals and not allowed to be clumped together. If the stem cells begin to clump together they do not remain unspecialized and begin to form different types of cells.Scientists are currently working on ways to modify the cells to manipulate which cells they split into. Different ways scientists have approached this is by...

Mitosis Lab Essay

514 words - 2 pages Recently my partner and I partook in a lab where we learned about the mitosis of cells. The mitosis of allium, the onion root tip, to be more exact. The purpose of this lab was to observe dividing cells and to be able to recognize different stages of mitosis. We would also determine the relative lengths of each stage of mitosis for the allium. Our hypothesis was that the telophase stage would last the longest in the process of mitosis for the
