  37. Cell Cycle • Interphase • Mitosis- PMAT • Cytoplasmic division • Differentiation

  38. Interphase http://www.obgynacademy.com/basicsciences/fetology/genetics/

  39. Mitosis Prophase Metaphase Anaphase Telophase

  40. Prophase http://legacy.owensboro.kctcs.edu/gcaplan/anat/images/Image173.gif

  41. Metaphase http://wps.aw.com/wps/media/objects/443/453744/metaphase.html

  42. Anaphase http://micro.magnet.fsu.edu/micro/gallery/mitosis/earlyanaphase.html

  43. Telophase http://botit.botany.wisc.edu/images/130/mitosis/allium_root_prep._slides/telophase_cytokinesis.html

  44. Cytoplasmic Division http://www.bing.com/images/search?q=cytoplasmic+division&FORM=BIFD&adlt=strict#

  45. CELL DIVISION CONTROL • VARIES BY ? • ~50 X • TELOMERES • STRESS CAN SHORTEN LIFESPAN • KINASES AND CYCLINS • CELL SIZE ? • EXTERNAL CONTROLS: HORMONES, GROWTH FACTORS • SPACE • CONTACT INHIBITION

  46. INFREQUENT MITOSIS = • TOO FRQUENT • TUMOR • BENIGN • MALIGNANT: METASTISIZE • ONCOGENES • TUMOR SUPRESSOR GENES

  47. STEM CELLS DIFFERENTIATION STEM CELL-> STEM CELL OR PROGENITOR CELL PROGENITOR CELL: TOTIPOTENT STEM CELL PLURIPOTENT STEM CELL MOST ORGANS HAVE PLURIPOTENT STEM CELLS OR PROGENITOR CELLS HOW DO CELLS IN BODY DIFFER?

  48. CELL DEATH • APOPTOSIS • PROGRAMMED CELL DEATH • EMBRYO • DEATH RECEPTOR RELEASES ENZYMES: CASPASES • DESTROY DNA REPLICATION ANDS REPAIR ENZYMES • ACTIVATE ENZYMES THAT SNIP UP DNA • DISSOLVE CYTOSKELETON • DESTROY MITOCHONDRIA ? • SEPARATE CELLS • MEMBRANE TRIGGERS TO ATTRACT PHAGOCYTES

  49. APOPTOSIS CELL HAS CIRCULAR SHAPE; BULGES: BLEBS; NUCLEUS SHATTERS; CELL SHATTERS; CELL FRAGMENTS ENCAPSULATE SO NO INFLAMMATION; GONE

  50. Necrosis http://herkules.oulu.fi/isbn9514266676/html/graphic11.jpe
