Medical Issues- Stem Cells Click on The Nature of Stem Cells to answer the following questions. 1.) Compare a stem cell and a specialized cell. Specialized cells carry out specific functions. These specialized cells are called differentiated cells. On the other hand‚ a stem cell is undifferentiated. Its role in the body is not yet determined. A stem cell can give rise to multiple cell types‚ including many stem cells. 2.) Describe a blastocyst. The blastocyst looks like a lopsided hollow ball

millions of times to form the approximately six billion cells that make up the human body. These types of cells (4 to 7 day old embryo) are called embryonic stem cells that are unspecialized and have the ability to renew themselves and give rise to specialized cell types (they have not yet developed into cells that perform a specific function). A stem cell is uncommitted and remains that way‚ until it receives a signal to develop into a specialized cell‚ unlike a heart or muscle cell for example. Their

Medicinal Plants And Their Medicinal Values ALOE VERA FLOWER • Aloe Vera is used in traditional medicine as a multipurpose skin treatment. In Ayurvedic medicine it is called kathalai‚ as are extracts from agave.[59]:196 for aloe:117 for agave Early records of Aloe Vera use appears in the Ebers Payrus from the 16th century BC‚[17]:18 and in Dioscorides’ De Materia Medica and Pliny the Elder’s Natural in the mid - first century AD.[17]:20 It is also written of in the Juliana Anicia Codex of 512 AD

The capability to revert blindness‚ cure diabetes‚ let paralyzed people walk again‚ replace deficient organs with newly grown ones and cure blood diseases are a few of the many potential functions of stem cells. A stem cell is an unspecialized cell that can develop into many different cell types in the body during early life and growth it also has the ability to divide essentially without limit. Unlike mature cells‚ which permanently have the same function‚ stem cells

Plant/Animal Comparison On this planet‚ there are many types of organisms. Many of these are plants and animals. Organisms must have certain essential systems in order to survive. However‚ how these systems uphold their structure between plants and animals is very diverse—even different animals have different structural systems‚ varying on the species quite greatly. Structural Systems The structural system of an animal is made of bones‚ quite commonly. It also may be made of cartilage‚ the material

SANCTITY OF LIFE We all have different viewpoints when it comes to Embryonic Stem Cell Therapy. Majority of the individuals believes that it violates the sanctity of life because they consider the act of destroying a human blastocyst is equal to killing a human being. Embryos are considered humans from the moment of the union of the gametes; hence‚ it can be relayed as the weakest members of society. It is morally wrong to exploit the weak merely because some benefit can be derived from it

Introduction Human embryonic stem cells (hES cells) are currently discussed not only by the biologists by whom they were discovered but also by the medical profession‚ media‚ ethicists‚ governments and politicians. There are several reasons for this. On the one hand‚ these ‘super cells’ have a major clinical potential in tissue repair‚ with their proponents believing that they represent the future relief or cure of a wide range of common disabilities; replacement of defective cells in a patient

from human embryos‚ which were then discarded‚ to devise stem cells‚ cells that are the initial undeveloped form of all human cells and can therefore be used to replace any damaged‚ diseased or disabled cell. Upon the release of Thompson’s studies involving stem-cells and the subsequent destruction of human embryos the United States media‚ health care system and government have been enraptured in a contentious debate over the use of stem-cells and their research. While many individuals‚ entities

Hemp vs. Marijuana No plant is more misunderstood than hemp — or more confused with marijuana. In fact‚ for some‚ hemp is just another word for marijuana. But in reality‚ nothing is further from the truth. The distinction between marijuana and hemp is often muddled because while they’re both bred for different and specific uses‚ they’re still distant cousins that yield from the plant. So then‚ what exactly are the differences between these two strains? Each bred for specific purposes It’s true
