Inner cell mass

is stem cells, which is a kind of the most important cells because it is a foundation for the development and growth of other lots of different cell types. There are many other tissues they are working with internal repair system and they also can divide necessarily for supplement to other cells if they are still alive. But, the condition is different of stem cell, which has two major functions compare with other cell types, remaining a stem cell continually or transforming to other cells that have

Nucleus is the dominant organelle controlling all the activities of the eukaryotic cell. Schneider and Schwann (1838 & 1839) believed that the nucleus had a central role in the growth and differentiation of an organism. Some cells like the sieve tubes of vascular plants and red blood cells of mammals do not possess nuclei during the major part of their existence. They, however, possess nuclei during early stages of their development. The prokaryotes have an incomplete or incipient nucleus without

Bush revealed his long awaited decision on federal subsidy of scientific research on human embryonic stem cells. These cells are a distinctive type of cells in human embryos that have the capability to produce any type of tissue in the human body. Many individuals were expecting that the federal government would provide funding this research. They wanted to hear about whether embryonic stem cells would be developed in laboratory, into tissue and organs that could be utilized to treat or cure numerous

TASK 2 i. Name and describe the four main types of tissues in animal ii. Describe the two types of Plant cell and their function FOUR MAIN TYPES OF TISSUES IN ANIMAL There are four types of main tissues in human body 1. Epithelium – Epithelium tissues are composed of layers of the cells that are closely packed together which is specialised to form the covering or lining of both external and internal surface of body such as surface of your skin and internal digestive system. The main function of

Using Non-Embryonic Stem Cells to Cure Degenerative Diseases Biological concepts and processes A stem cell is an undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation. In simpler terms, it is a cell which has the potential to develop into a number of different cell types in the body. Because they are undifferentiated/unspecialised, this makes them capable

Stem cells are cells which can be specialised to become any type of cell which is required in the body. Stem cells come from the embryos formed during the blastocyst period and from adult tissue. Adult stem cells which are found throughout the body are found in different types of tissue. Stem cells are found in tissue such as bone-marrow, blood vessels, skin and the liver. Stem cells are referred to as blank cells because they are unspecialised and do not have any particular function. The role

kills off all the pancreatic beta cells that produce the insulin needed for glucose regulation in the body. (2) Finding a cure for type 1 diabetes would be one of the most successful thing we can do. By testing a human insulin producing cell, we can see if injecting a type 1 diabetic with the insulin producing cell that would then help generate their own insulin producing cells. Hypothesis: My hypothesis is by using stem cells to create human insulin producing cells we can eliminate Type 1 diabetes

treated with the use of embryonic stem cells. Embryonic stem cells are cells derived from the undifferentiated inner mass cells of human embryo. In simpler terms, these cells have the ability to develop into any of the two hundred different cell types in our bodies. Unlike most of the cells in our bodies, such as heart cells or skin cells, which conduct a specific function, a stem cell does not have a specific function until it is specialized (Hogan). A stem cell that is becoming specialized will go

The body contains trillions of cells, and within one of those cells are thousands of miniscule organelles. They provide a eukaryote with the ability of cellular respiration. Cellular respiration is defined as: "…a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products". Basically these organelles produce energy, and that is what allows us to live. They are called
