IB Biology on Genetics and Stem Cells

IB Biology on Stem Cell and Induced Pluripotent Stem Cells
Picture taken from
Brief Introduction on Stem Cells.
  • Self Renewal and Unspecialised cells which are able to specialised into any 220 cell types
  • Able to give rise to any 220 cells type
  • Two types Embryonic Stem Cell and Adult Stem Cell
  • Totipotent give rise to all cells
  • Pluripotent give rise to all cell types
  • Multipotent give rise to limited cell types
  • Unipotent only one cell type

Latest Update on Obama Administration on Stem Cell Research
On March 9, 2009, President Barack H. Obama issued Executive Order 13505: Removing Barriers to Responsible Scientific Research Involving Human Stem Cells. The Executive Order states that the Secretary of Health and Human Services, through the Director of NIH, may support and conduct responsible, scientifically worthy human stem cell research, including human embryonic stem cell (hESC) research, to the extent permitted by law.

Keynotes from Obama
False choice between Sound Science and Moral values. We need to ease human suffering and must have the capacity to care. Humanity and Conscience to conduct research in a responsible manner. Some strongly opppose but the potential it offers is great. Stem Cell Research has open up!
Potential for great benefits with opening of many Stem Cell lines

Keynotes from CNN on Moral and Ethical Issues
IVF embryonic stem cells are discarded if not used. Use them for Stem Cell Research for treatment of Spinal cord and many  diseases. Throw them away or Use to Save Lifes
Embryos come from IVF and used for therapeutic research

Surplus or excess embryos in IVF  will be discarded. Why not donate for Research. Embryonic Stem Cells will benefit Stem Cell Research if donated instead of throwing them away.

Why Embryonic Stem Cells (ESC) are pluripotent and far better than Adult Stem Cells (ASC) which are multipotent. Click HERE to get more info about

  1. If you need your ex-girlfriend or ex-boyfriend to come crawling back to you on their knees (even if they're dating somebody else now) you must watch this video
    right away...

    (VIDEO) Want your ex CRAWLING back to you...?
