    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 different cell types. Most of the time stem cells would regenerate into the specific cell of the tissue the stem cell is situated although they are still able to take the form of any type of cell. This occurs only under specific conditions. Stem cells…

    While Sickle Cell Anemia is more common in certain ethnic groups, people should be aware of sickle cell. Sickle Cell Anemia affects 1 out of 13 people and is diagnosed at birth. People with this disease live a life struggling pain and uncertainty. On the 15th of November 1910, Dr. James Herrick made the first discovery of sickle cell disease. He encountered multiple patients complaining of similar symptoms of acute chest pain. Dr. Herrick received a blood film, a test used to look for…

    Neurons are not the only cells that occupied the central nervous system (CNS). In fact, neurons are outnumbered by supportive non-excitable cells, collectively called neuroglia (a.k.a. glia). The term glia was coined by Rudolph Virchow in 1859 to indicate the “connective tissue” surrounding the neurons (glia came from Greek meaning glue). However, the combination of the activities of glial cells and neurons is crucial for brain functions (Steward 2000). There are three types of glial cells in…

    three main types of stem cells, it appears that each have their own purposes and advantages in different types of situations. Embryonic stem cells can be used in a wide variety of treatments, and they excel because of their ability to transform into any other type of cell. Because they can change into any type of cell, they can be used to repair specific parts of the body that other stem cells cannot. They are the master key to the body, but if placed in the body undifferentiated, they can…

    We know that all living things need to make cells to survive. Old cells die and need to be replaced. In order for living things to continue to grow, cells are constantly being made. OpenStax states that the process of new cells being made is called cell division (2013). There are three types of cell division and those are binary fission, mitosis, and meiosis. Binary fission is a quick and simple process involving replication, elongation, separation, and daughter cells. Meiosis and mitosis are…

    HL-60 cells were derived from the blood cell of a patient with acute promyelocytic leukemia, which proliferates continuously. They are immortal cells, until they induce differentiation using chemical reagents such as retinoic acid. After differentiation, they are no longer immortal. Retinoic acid is derived from Vitamin A, and can induce granulocytes. We are going to test whether exposure of longer time to retinoic acid will induce greater percent of granulocytic differentiation. To test…

    composed of many cells or more than one cell performing differing functions. A multicellular organism should have cells that contain the same genetic information. Until now, information regarding multicellularity is still a mystery because the ability to go further is still not that sufficient. The reasons behind this lack of background are the “long ago” divergence from the common unicellular ancestor of the organisms and the lack of good model system to represent such cellularity. In terms of…

    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…

    Centriole (E) Their structure is a small network of protein fibers which are not surrounded by a membrane but are located in an area of the cell called the centrosome. The centriole has its appearance and structure the way it is because its arrangements must be a circular and the triplet fibers that it’s made out of will eventually create a shape that is similar to a barrel when it it is arranged. One of their main function is to contribute/help with processes that involve cellular activities.…

    Cell division is essential in the life cycles of all cells. It allows living organisms to reproduce and therefore not die out. There are two major steps to cell division: nuclear division and cytokinesis. Within nuclear division are two different types: mitosis and meiosis. Mitosis is a form of asexual reproduction in which one diploid parent cell is divided into two identical diploid cells. On the other hand, meiosis is an example of sexual reproduction, in which two diploid parent cells both…
