  • 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.

  • Cancer and Cell Fate in the Intestinal Epithelium

    Cancer and Cell Fate in the Intestinal Epithelium

    Animation

    (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

    Animation

    (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

    Poster

    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

    Clip

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

  • Classroom Activities: Planaria Regeneration Activity

    Classroom Activities: Planaria Regeneration Activity

    Activity

    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

    Animation

    (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.

  • Zebrafish Heart Regeneration

    Zebrafish Heart Regeneration

    Animation

    (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.

  • X Inactivation

    X Inactivation

    Animation

    (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

    Animation

    (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.
