Research into and the potential uses of stem cells The discovery of stem cells was a significant scientific breakthrough. They were first discovered in mice in 1981 and then in humans 17 years later in 1998. Stem cells have the potential to revolutionise modern medicine. They have the potential to offer cures for diseases, treating injuries that can’t be helped currently and dramatically change how drugs are developed. These possibilities have huge impactions to New Zealand as we have thousands…

fertilized egg begins to form a mass of cells called a blastocyst. It is from this mass of cells that all of the human body originates from. The nuclei of all of the cells in the blastocyst contain genes that turn some cells into bone cells and others into skin cells. The cells found in the inner mass of the blastocyst are called embryonic stem cells and have the potential to differentiate into almost all other cells in the body; the pluripotency of these cells makes them very viable in the…

known as a cell. Organisms are also a living thing and cell is considered to be the basic block of organisms that builds them. There are many different types of cells in a living thing and are divided into two main categories (i) prokaryotic and eukaryotic. (Karp, 2010). Characteristics of living cell Cells are considered as the most fundamental unit that has the responsibility to carry functions within a living organism (De Robertis & De Robertis, 2006). The characteristics of living cells…

From one cell to two-hundred different kinds of cells. Cell differentiation is the process of a cell changing from one cell type to another in developmental biology. In this process stem cells are used. A stem cell is a cell that has the ability to continuously divide and differentiate into various other kinds of cells or tissues. The process of differentiation results from the protein make-up of a cell. The blueprints for making these proteins are found in the nucleus of each cell as DNA; thus,…

Plant cells are eukaryotic cells, or cells with a membrane-bound nucleus. Unlike prokaryotic cells, the DNA in a plant cell is housed within the nucleus. In addition to having a nucleus, plant cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation. Organelles have a wide range of responsibilities that include everything from producing hormones and enzymes to providing energy for a plant cell.…

lab, cell size activity, was to determine how small cells are, and how do different cells compare to each other in size. For this lab, I didn’t have a hypothesis, but I did learn many new things that I didn’t expect to learn. First of all, I learned that a salt crystal is significantly larger than even the largest of cells that we used in this experiment. And that says something because a salt crystal is very little, and our own human eyes can barely see it. This means that all of the cells…

understand and observe cells. Let us begin with the ABC’s of the Cell Theory which splits into 3 major parts: All living beings are made up of cells Cells are the basic unit of structure in all organisms All cells come from preexisting cells. To have a deeper understanding of the statements above, which is, in fact, the simplified version of this vast topic, let’s refer to the Venn diagram below: It shows that in biology, not all living organisms are composed of the same cell.…

nucleus. To start off, I am going to start with the one in charge of the whole cell or town. The one that is in charge of the cell is the nucleus. In a town it is the mayor or the town hall. There is a reason why I way that is because the mayor makes the laws in the town hall, so basically the mayor is the nucleolus and the town hall is the nucleus.…

Introduction Cells are the building blocks of the diverse idea we call life, which means that they must be as diverse as life as well. Prokaryotic and Eukaryotic cells make up most of the life on this planet, and vary widely in function, while still sharing some similarities. Prokaryotic cells, although simpler and smaller, make up most life. A nucleoid region contains a loop of nucleic acids known as a DNA plasmid. Prokaryotic cells contain simplified ribosomes which free float in cytoplasm…

Gene Therapy & Cancer Cells Gene therapy is often defined as a treatment that uses genes to cure or prevent diseases. Genes, DNA, and protein are all involved with each other, therefore, in many immune diseases, if one fails your whole immune system could eventually fail. This treatment is relatively new; hence it is still a pretty risky experimentation since it involves getting genes into cancer cells. Gene Therapy is often involved in serious cancer cell treatments; its main purpose is to try…
