  • Cancer Cell Invasion

    Cancer Cell Invasion

    Phenomenal Images

    Students explore a photo of tissues and cells as an anchoring phenomenon to explore the invasion of cancer cells into muscle tissue.

  • Role of p53 in the Cell Cycle

    Role of p53 in the Cell Cycle

    Data Points

    Researchers investigated the role of p53 in cell cycle regulation by genetically engineering a cell line with deleted copies of the p53 gene. They exposed the cell lines to DNA-damaging radiation and observed how this exposure impacted mitosis.

  • Cell Division and Cancer Risk

    Cell Division and Cancer Risk

    Data Points

    Cancer is typically attributed to hereditary and environmental factors, but these only explain a fraction of overall cancer risk. In this study, researchers investigated how a third factor—chance genetic mutations that occur during stem cell division—may contribute to the overall rate of cancer incidence in different body tissues.

  • Genetic Mutations and Disease Interactive

    Genetic Mutations and Disease Interactive

    Click & Learn

    This interactive focuses on the roles of germline and somatic cell mutations in human disease. It supports the 2013 Holiday Lectures on Science, Medicine in the Genomic Era.

  • The Eukaryotic Cell Cycle and Cancer

    The Eukaryotic Cell Cycle and Cancer

    Click & Learn

    Explore the phases, checkpoints, and protein regulators of the cell cycle in this highly interactive Click and Learn and find out how mutated versions of these proteins can lead to the development of cancer. Also available in Spanish.

  • Cancer as a Genetic Disease: Video Highlights

    Cancer as a Genetic Disease: Video Highlights

    Clips

    (8 min 32 sec) In this video Dr. Charles Sawyers provides an overview of the types of genes that, when mutated, can lead to the development of cancer. Also available in Spanish.

  • Cancer and Cell Fate in the Intestinal Epithelium

    Cancer and Cell Fate in the Intestinal Epithelium

    Animations

    (2 min 17 sec) Disrupting the normal processes of differentiation and maturation of the intestinal epithelial cells can lead to cancer. Also available in Spanish.

  • Development of the Cerebral Cortex

    Development of the Cerebral Cortex

    Animations

    (1 min 43 sec) Most of the neurons of the cerebral cortex arise from progenitor cells that undergo repeated cell division.

  • Genetic Mutations and Disease

    Genetic Mutations and Disease

    Posters

    The poster for the 2013 Holiday Lectures on Science, Medicine in the Genomic Era, illustrates the difference between germline and somatic cell mutations.

  • Growth cones in action

    Growth cones in action

    Clips

    (34 sec) The growth cones of two neurons sense and interact with one another.

  • Classroom Activities: Planaria Regeneration Activity

    Classroom Activities: Planaria Regeneration Activity

    Activities

    This activity uses the planaria's property for regeneration and compares how long it takes for planaria cut in different places to regenerate a head. 

  • Creating Embryonic Stem Cell Lines

    Creating Embryonic Stem Cell Lines

    Animations

    (1 min 38 sec) The inner cell mass (ICM) cells of blastocyst-stage early human embryos can be removed and cultured. These cells can be grown in the lab indefinitely. Various growth factors cause these cells to develop into a variety of differentiated cells, such as muscle or nerve cells.

  • Newt Limb Regeneration

    Newt Limb Regeneration

    Animations

    (1 min 21 sec) Urodele amphibians—newts and salamanders—are able to regenerate fully functional limbs in response to amputation. Cells in and near the limb stump dedifferentiate to form a mass of stemlike cells that can produce all the specialized tissues of the limb, such as muscle, nerves, and blood vessels.

  • Zebrafish Heart Regeneration

    Zebrafish Heart Regeneration

    Animations

    (2 min 30 sec) The zebrafish heart is similar to the human heart in many respects. But unlike the human heart, the fish heart closes wounds rapidly and then regenerates to nearly full function. Fibroblast growth factor (FGF) is an important molecule in the regeneration process.

  • Angiogenesis

    Angiogenesis

    Animations

    (1 min 12 sec) A cancer tumor forms in a bed of healthy cells. The animation goes on to show how the tumor recruits blood vessels and how metastasis occurs. Also available in Spanish.

  • X Inactivation

    X Inactivation

    Animations

    (55 sec) This animation shows how the random deactivation of one of the X chromosomes in a pair can lead to a mozaicism in the expression genes. 

  • Meiosis

    Meiosis

    Animations

    (5 min 53 sec) Meiosis, the form of cell division unique to egg and sperm production, sets the stage for sex determination by creating sperm that carry either an X or a Y sex chromosome. But what is it about the X or Y that determines sex? Also available in Spanish.

  • Bacterial Growth

    Bacterial Growth

    Clips

    (54 sec) Dr. Brett Finlay shows how bacteria can grow rapidly to incredible numbers, and also explains what limits this explosive growth.
