Document Summary

Reproduction to produce genetically identical daughter cells (mitosis) Bacteria have simplest form of cell division (fig. Cells that divide daily skin cells, intestinal cells, cheek cells. Gap phases cell is preparing for mitosis. Cell cycle between interphase and mitosis depending on need of organism. Occurs after g1, after g2, and after m. Stem cells undifferentiated cells from very early stage embryos (blastocysts) Adult stem cell cells from somatic tissues. Stem cells grown in culture produce stem cell lines for research. Cells divide for long period of time (25 years) Mitosis continues, cell grows endlessly (results in tumor) Programmed cell death (apoptosis) is reduced w/ cancer cells. Benign occurs in one location in the body. Metastasis new tumors from parts with cancer. Angiogenesis redirection of blood vessels to tumor. If able to stop signal, can stop growth. Tumors have higher level of tyrosine kinase than normal. Genes mutate in cancer, cells divide more as a result.
