Promising Medical Applications for Embryonic Stem Cells - Promising Medical Applications for Embryonic Stem Cells Special cells that are taken from human embryos, called embryonic stem cells (ES cells), actually possess the power to save your life. The importance of embryonic stem cells rests in their lack of specialization. These basic cells are present in the earliest stages of developing embryos and are able to develop into virtually any type of cell and tissue in the body. Being self-renewing, they offer a potentially limitless source of cells and tissue....   [tags: Exploratory Essays Research Papers]

Embryonic Stem Cells Unnecessary for Medical Progress - Embryonic Stem Cells Unnecessary for Medical Progress Reporting on new research by Dr. Donald Orlic of the National Institutes of Health and others, indicating that adult bone marrow stem cells can help repair, and restore function in, damaged hearts: "Until now, researchers thought that stem cells from embryos offered the best hope for rebuilding damaged organs, but this latest research shows that the embryos, which are politically controversial, may not be necessary. 'We are currently finding that these adult stem cells can function as well, perhaps even better than, embryonic stem cells,' Orlic said." - "Approach may repair heart damage," MSNBC, March 30, 2001 (www.msnbc.c...   [tags: Argumentative Persuasive Topics] 1526 words

Sickle Cell Anemia - The problem is that sickle cell anemia affects about 72,000 Americans in the United States. Sickle cell anemia is an inherited disease in which the body is unable to produce normal hemoglobin, an iron-containing protein. Abnormal hemoglobin can morph cells that can become lodged in narrow blood vessels, blocking oxygen from reaching organs and tissues. The effects of sickle cell anemia are bouts of extreme pain, infectious, fever, jaundice, stroke, slow growth, organ, and failure. Sickle cell anemia hurts many people today in fact it hurts about 72,000 Americans....   [tags: essays research papers fc]

Formation of the Trophectoderm Lineage - ‘Formation of the trophectoderm lineage. The first cell fate decision in mammalian development’. The crucial outcome of the early mammalian development is the attachment of the embryo to the uterine lining. The cell population that will support this attachment, the trophectoderm (TE), is distinguished from the inner cell mass (ICM) at the blastocyst stage and this separation represents the earliest lineage restriction. Up to the 8-cell stage, the embryo is characterized by a loose structure, but then compaction follows, a phenomenon mediated by increased cell-cell adhesion (tight junctions, increased E-cadherin expression)....   [tags: Anatomy, Cell Division] 1629 words

Grow Little Cell Grow! Investigating Neurogenesis - Grow Little Cell Grow. Investigating Neurogenesis Neurogenesis, the production of new nerve cells, has been a revolutionary finding as nerve formation has always been thought to end with adulthood. It has not been until recently that such dogma has been contradicted as research findings report that neurogenesis continues in the hippocampus throughout most of the adult life of mammals and primates (1). Recent correlations have been further made between neurogenesis and depression as the latter depletes neuron cells in the brain while antidepressive drugs have demonstrated to increase neuronal growth (2)....   [tags: Biology Essays Research Papers]

Asexual Reproduction: Somatic Cell Nuclear Transfer - Cloning (asexual reproduction) is the production of individuals who are genetically identical to an already existing individual. The procedure is called somatic cell nuclear transfer. Scientists take a mature, unfertilized egg and remove its nucleus. Next, they, introduce a nucleus obtained from a specialized (somatic) cell of an adult organism. Once the egg begins to divide, they transfer the embryo into woman's uterus to initiate a pregnancy. Since almost all the hereditary material of a cell is contained within its nucleus, the re-nucleated eggs are genetically identical to the organism that was the source of the transferred nucleus (Kass, 2001)....   [tags: genetically identical, cloning]

Interestingly, neural precursor cells are not just a homogenous population but rather specified in space- and time-related manner. This spatiotemporal correlation has generated huge diversity of neural precursor cell types repertoire.

Acquired Immunodeficiency Syndrome -   INTRODUCTION Viruses are infective organism that infect living cells in order to reproduce and live. The word virus is derived from a Latin word which translates as “Poison” or “Toxin”. Viruses typically consist of a nucleic acid molecule in a protein coat and are alive only inside the body of a host. Alone, they are rather inert. For about 100 years, the scientific community has repeatedly changed its collective mind over what viruses are. First seen as poisons, then as life-forms, then biological chemicals, viruses today are thought of as being in a gray area between living and nonliving: they cannot replicate on their own but can do so in living cells and can also affect the behavior o...   [tags: virus, retrovirus, host cell, disease, DNA, RNA]
