Cellular differentiation

Tissue repair is a process of wound healing. It occurs in our body all the time; we just don’t take notice because it is a process not seen by the human eye. However, many magical things happen throughout our body that we cannot see. The body’s tissue repair process is one of those magical things. It is with our daily regular activities that our cells in the stratum corneum of the epidermis are shedding daily. We constantly replace our cells in this layer and lucky for us, our epithelial tissues…

Before one is capable about having a deep discussion about stem cells he must understand some of the key terms involved in stem cell research. The first term is totipotent. Totipotent cells are the cells of the zygote. These cells are able to develop into any type of cell inside or outside the body. An example of cells that are considered outside the body is the placenta. The ability for totipotent cells to develop into cells outside the body is what separates it from pluripotent cells.…

Romanticizing his need for knowledge and infamy, the protagonist, Victor Frankenstein, of Mary Shelley 's 1818 novel, Frankenstein, asserts, "No one can conceive the variety of feelings which bore me onwards, like a hurricane...Life and death appeared to me ideal bounds...I should... pour a torrent of light into our dark world" (Shelley 94). In the novel, Victor essentially recreates life, a task normally attributed to God, without fear of the moral consequences. In modern science, many…

If anyone has ever been severely injured, seriously ill or has cancer, stem cells may help repair the damage or cure the disease. For instance, a leukemia patient can undergo a stem cell transplant and be cured of cancer. Stem cell research has made several advances in the medical field. It has helped and even cured many people with serious diseases and illnesses. Even though stem cell research has benefited many people, it has also been associated with negative controversy. Stem cell…

Growing embryonic stem cells in labs can create millions. These cells can then be frozen and sent to other labs for further experimentation (“Stem Cell Basics”). So creating stem cell lines is what the scientists are doing in their labs or using existing stem cell lines to research embryonic stem cells. Stem cell lines are a large number of cells, all carrying the same genes, grown in laboratories through many cycles of growth and division over a lot of generations of cells. One cell line can be…

removed in a blastocyst stage where there are only approximately 180 to 200 cells composing a small mass known as the embryo. Adult stem cells differ from hESCs because they have already differentiated into specific tissue types. The difference in differentiation between hEScs and adult stem cells is important when scientifically discussing scientific research and the future of medicine. However to many, it is not the science that is up for debate between adult and embryonic stem cells, it is…

to specialized cells. The process of differentiation can happen with these cells. Differentiation is where unspecialized embryonic cells receive features of specialized cells. Examples of this process is the heart, liver, or muscle cells. Differentiation is controlled by signaling pathways, inside and outside of the cell, involving proteins. These signals tell the cell which step to go…

Medical Stem Cell Usage Stem cell research and therapies have the ability to perform medical miracles. There are ethical and legal justification concerns surrounding the topic that are holding back huge advances in therapeutic studies and cures to diseases. Lifting certain restrictions on stem cell therapies and research could provide new ways and opportunities to save lives. Stem cell research should be continued further and given more legal wiggle room due to it’s enormous medical…

Stem Cells are they ethical? The use of stem cells has a lot of potential, whether used to cure otherwise incurable diseases like Parkinson 's disease, Alzheimer 's disease, diabetes, or a spinal cord injury. Stem cells can also be used to create new organs to save thousands of lives every year for the people that need an organ transplant. Like all things though there are some downfalls. In order to obtain these critical stem cells, it involves the destruction of human embryos. In turn, it…

that aren’t specialized for any specific tissue undergoing the process of mitosis to renew themselves and within specific and controlled factors, the not unspecialized cells can be evolved into certain types of tissues through the process of differentiation (2009). Scientists have recently focused and researched on two types of stem cells found in humans and animals: embryonic stem cells and adult or somatic stem cells (2009). These two types of stem cells can be used to take the place of dead…
