  • Abortion Controversy

    cells cease to be, and their union generates a new and distinct organism. This organism is a whole, though in the beginning developmentally immature, member of the human species. Readers need not take our word for this: They can consult any of the standard human-embryology texts, such as Moore and Persaud’s The Developing Human, Larsen’s Human Embryology, Carlson’s Human Embryology & Developmental Biology, and O’Rahilly and Mueller’s Human Embryology & Teratology. Human embryos, whether they are formed by fertilization (natural or in vitro) or by successful somatic-cell nuclear transfer (SCNT — i.e., cloning), do have the internal resources and active disposition to develop themselves to the mature stage of a human organism, requiring only a suitable environment and nutrition. In fact, scientists distinguish embryos from other cells or clusters of cells precisely by their self-directed, integral functioning — their organismal behavior. Thus, human embryos are what the embryology textbooks say they are, namely, human organisms — living individuals of the human species — at the earliest developmental stage.” Given this small amount of information, one can see that life truly begins at the moment of conception. If murdering a man is not okay, why is it not considered a crime to kill an innocent baby? Civilized societies do not permit one human to intentionally harm another without punishment. Abortion is murder! Every child is a precious gift from God and we have no right to…

  • Epimorphic Limb Regeneration

    Many of the tasks that multi-cellular organisms perform are truly inspiring, from embryogenesis to organogenesis and other developmental processes. Developmental biology covers some of the most interesting procedures of the formation and transformation of living beings. One question in particular that sparked my interest in the vast field is how certain species of animals are able to completely reform a limb after it has been entirely severed. Such a feat is completely and utterly astonishing.…

  • Embryonic Development Essay

    Features of embryonic development in a chick and discussing Introduction During this essay, the features of embryonic development are analysed and comparisons between the developments of different species will be explored. Developmental biology is the study of the activity which leads to the growth and maturation of organisms.[1] The Red Jungle Fowl (Gallus gallus) is thought to be the ancestral to the modern domestic chicken. (Fumihito et al., 1994). [1] Chickens have had a long association…

  • Cell Differentiation Essay

    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,…

  • Essay On Bone Marrow

    Bone Marrow Bone marrow is soft, gelatinous tissue found in hollow spaces in the interior of most bones. It is highly vascular and enriched with many blood vessels and capillaries. The average weight of bone marrow is about four percent of the total body weight (Bone Marrow Anatomy). Bones that contain bone marrow are: the hip bone, breast bone, skull, ribs, vertebrae, shoulder blade and thigh bone. Bone marrow contains immature cells, called stem cells. It is the place where new blood cells…

  • Pro Stem Cell Research Argument

    Stem cell research. Those three little words may seem so simple, but the mixed reactions and controversial propaganda that surround the topic are staggeringly diverse. Stem cells are very unique cells that have the ability to morph into any of the types of cells found in our bodies (Newton 3). Blood, heart, nerve, and skin are all types of cells that stem cells have the potential to turn into. Due to this, stem cells could quite easily cause revolutionary breakthroughs in the medical scene,…

  • Cancer Stem Cells Essay

    complex structures within the human body, and they can also produce tumors. The properties of stem cells have a large implementation of how cancerous stem cells survive and replicate. Elimination of these cancer stem cells presents a complex challenge because in order to remove the stem cell it must first be targeted and eradicated using critical therapeutic approaches. The properties of cancer stem cells are used to develop new strategies for removal of these cells from the human body, and…

  • Pros And Cons Of Cord Blood Banking

    What Are the Pros and Cons of Cord Blood Banking? Researchers and physicians are always studying more about treating various illnesses. Stem cell transplant has become one of the most promising methods of treatment, using 3 types of cells—those from bone marrow, blood and umbilical cord—to give patients new cells that will grow into healthy ones. While the first two require a separate donor who must be a close match to the individual who is needing treatment, umbilical cord stem cells are…

  • Sources Of Stem Cell Research

    One they display markers known to characterize ES cells and they undergo several generations of cell division, and two demonstration that they constitue a stable, or immortalized, cell line.” (Scientific America, June 2014) Yet still the amount of material that can be derived this way is truly limited even under the best circumstances. Results from several studies indicate that only 60% of all spontaneous abortions bring up specific fetal abnormalities; specific chromosomal abnormalities had…
