Cluster of differentiation

Cepheid Variable Stars are large and luminous yellow stars in space known to sporadically change size and temperature resulting in pulsing variations in brightness and thus, inconsistent levels of luminosity. There are two types of Cepheid Variable Stars; Type 1 Cepheids (or classical) which are high mass stars with smaller pulsating periods and Type 2 Cepheids which are lower mass stars with greater pulsation periods. All Cepheid Variable Stars, named after the first observed star of this type,…

and this is called the blastocyst of which has two fragments. The first is the outer layer of cells that creates placenta which maintains the embryo as it progresses within the uterus and this is known as the trophectoderm. The second is the inner cluster of cells which is a clump of approximately 10-20 cells and is known as the inner cell mass. The cells within this orb are unspecialised and will continue to proliferate in order to differentiate into the essential cells that will develop the…

of mammalian). Adult SCs have been identified in tissues including skin, intestine, liver, brain, and bone marrow. An adult SC can divide and create another cell like itself, as well as a more differentiated cell. However the capacity for differentiation into other cell types is limited and is known as being multipotent. Multipotency is a unique feature of adult SCs compared with the pluripotentcey found in embryonic SCs (Arthur, adult human dental pulp stem cells) (Arthur, implanted adult…

Question 2 What are stem cells (what characteristics define them)? Stem cells are cells that has the potential to develop into different cell types in the body during early life and growth. They serve as an internal repair system , dividing essentially without limit to replenish other cells as long as the person is alive .When a stem cell divides it can either remain as a stem cell or can develop into a cell with more specialized function like muscle cell, red blood cell etc. Two…

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…

Embryonic Stem Cell is Pertinent to Finding Cures Diseases, sicknesses, burns, and infections: how can this world ever be cured? It was not until recently in 1998 when a promising cure was discovered, the embryonic stem cell (ESC). According to Christine Watkins in one of her social issues books titled Human Embryo Experimentation, ESC was discovered by both James Thomson at the University of Wisconsin and John Gearhart at the University of Pennsylvania (10). Thomson, a director of regenerative…

STEM CELLS Stem cells are very homogenous due to the fact that they are of the same family type or lineage characteristically speaking. They are differentiated from other cells by two features. The first feature is that they are able to divide by cell division and the second feature is that under specific experimental conditions they can be directed to become tissue cells with certain functions. Stem cells are able to transform or regenerate themselves growing into the body’s approximately 200…

Introduction Stem cell research has caused a great deal of controversy throughout the past several decades. Stem cells are unique because they can develop into different cell types in the body. While the stem cell is dividing, the new cells that are being created can turn into specialized cells, such as, brain cells or red blood cells. As a result, the specialized stem cells could help people suffering from a plethora of diseases, specifically Alzheimer’s disease. Despite the many benefits…

Isaiah Juarez(current research) There are many different uses for stem cells, and different stem cells which can do things other stem cells can and can do. There are two main stem cells, and they the embryonic stem cells, and adult stem cells. However there ae about another dozen more stem cells which are also important to the human body. These other stem cells are tissue stem cells, blood stem cells, skin stem cells, Mesenchymal stem cells, stem cells in the eye, induced plum stem cells,…

Cells are the BASIC function of life on Earth. They are the fundamental unit of all living things. The cell is the smallest structure in the human body and has all the properties of be alive and being it 's own living thing and stem cells are the direct result of cells being their own living thing. The stem cell is stated to be “unspecialized cells that are thought to be able to reproduce themselves indefinitely and, under the right conditions, to develop into mature cells, e.g., nerve, skin,…
