Pros And Cons Of Stem Cell Research

Stem cells are a special group of cells found in all multicellular organisms. What makes them unique and different from other cells is the fact that they are unspecialized and have the potential to differentiate into diverse cell types while still maintaining the ability to replenish themselves. Generally, these cells are divided into 2 broad categories – the embryonic stem cells that are derived from the inner cell mass of the blastocyst and the adult stem cells that are harvested from the bone marrow, umbilical cord blood or the adipose tissue of an adult.

is a stem cell? Well basically they are cells in the human body that exist in a sort of neutral

Embryonic stem cells are found in human blastocysts (Marcovitz 17). A blastocyst is a very young embryo (just a few days old) that contains around 200 undifferentiated stem cells (Marcovitz 17). German Zoologist Valentin Hacker coined the term “stem cell” after he discovered them in a blastocyst of a crustacean (Marcovitz 18). Embryonic stem cells were collected for the first time in 1988 by Dr. James Thomson of University of Wisconsin and by Dr. John Gearheart of Johns Hopkins (Panno 76). These stem cells are unspecialized; they do not perform a specific function like cells such as muscle and nerve do (“Stem Cells”). They are also pluripotent, meaning they have the ability to divide and become specialized cells (“Stem Cells”). This is why stem cells hold so

Stem cells are used in treating different diseases because embryonic cells can form into the cell type needed, then those cells replace the ones that were damaged by the disease. They can be used in a bone marrow transplant.

First of all an understanding of what a stem cell is, where it comes from, and the significance of it's medical potential is essential. Stem cells are the "master cells" that form the human body or whatever other animal it is from. Stem cells can be extracted from adult tissues, bone marrow, umbilical cord blood ( ), and embryos in the blastocyst stage. Although scientists have found ways to manipulate the stem cells from adult sources into other types of cells, they claim that they are less capable of deriving the desired tissue and are not "biologically equivalent" ( ) to stem cells extracted from embryos.

There are a lot of potential uses of stem cells, but there are obstacles that we need to go through first. Stem cells can be used to test new drugs that scientists make. We could generate healthy heart muscle cells with stem cells. Injected cells could repair things in the body by secreting growth factors. Before scientists start

Firstly, what even are stem cells? Stem cells are cells that can turn into many different types of cells throughout your bedy. Think of it like a mother cell creating endless amounts of children. There are two kinds; pluripotent, ones that can turn into basically every cell in the body, and multipotent, ones that can only for a small number of cells.

There are multiple ways for stem cells to be obtained such as: Taking the cells from aborted embryos or fetuses, umbilical cords, adult tissues, or artificially creating embryos with a process known as a somatic cell nuclear transfer (SCNT). In this process “the nucleus of an egg is removed and replaced by the nucleus from a mature body cell, like a skin cell” (Arnes). Also known as cloning. However, creating embryos like this do not create stable stem cells. And taking stem cells from umbilical cords has the possibility to transfer unknown genetic disease and “has not yet demonstrated health and

Stem cells are special cells that have the ability to regenerate and repair damaged tissue. Embryonic stem cells appear to possess the ability to become almost any tissue within the body. This, in theory, means that a cell could be taken from one section of an embryo that may have become a part

Stem cells have an interesting history that has been linked with debate and controversy whenever it is brought up in a conversation in today's society. However, most people do not know the reasoning behind stem cell testing or using them to benefit society. It all started in the mid 1800s, stem cells were discovered as the cells that were the "building blocks of all the other cells." They serve as the body's own repair system. Stem cells can be vary in size, how they are obtained, and their benefits, they can help solve problems of an everyday human being, and can possibly find a cure for some of the most heartbreaking diseases on the planet.

Embryonic stem cells are used to generate new cells of almost any kind though the right stimulation (2008, explorable.com). Stem cell research is used for the investigating basic cells, which can develop into any organ in the body. Then embryonic stem cells are developed from a female egg after

Stem cells are different from normal cells because they don't have a specific type. They can become any cell. Since now a days many organs are in high demand and a matter of life or death for some people, it is important for medical research.

According to Alenzi, “Stem cells are immature, unspecialized cells that their developmental direction has not yet been determined” (19929), and because they do not yet serve any meaningful purpose, stem cells are capable of becoming virtually any specialized cell in the body; they can become nerve cells, blood cells, skin cells, and just about any other cell you can think of.

Embryonic stem cells are cells found in the human body that have not yet differentiated, or specialised meaning that they have not yet received the specific instructions to become a specific cell. They can be manipulated to turn into any kind of cell, for example, new skin cells for someone with melanoma. Stem cells are found in the placenta, umbilical blood, fat tissue, bone marrow and mew embryos. Embryonic stem cells have an advantage over the other sources of stem cells because the cells have less exposure to the outside world and are relatively easy to access, in situations like in vitro fertilization.

Stem cells are cells that have the capabilities to develop into many different types of cells in the body. Serving as a type of repair system for the body, they can theoretically divide without limit to take over for other cells for
