Transcript of Stem-Cells
of Stem Cells
Adult Stem Cells
Undifferentiated cells found throughout the body that divide to replenish dying cells & regenerate damaged tissues.
Primary role is to maintain/replace worn out cells when they die
How Are Stem Cells Extracted?
What Are Stem Cells?
Christopher Aguliar, Elias Carrillo, Ada Hernandez, Ikenna Khauv, Sylvanee Tapia, Estefania Tavarez
Religious groups against stem cell research:
US Roman Catholic bishops
Lutheran Church Missouri
Southern Baptist Convention
Pope John Paul II
"It is immoral to produce human embryos destined to be exploited as disposable biological material."
Stem Cell Research History
How Are Stem Cells Extracted?
In 1908, Alexander A. Maximow was the first to propose the term "stem cells" and deveoped his theory of hematopoiesis stem cells.
Embryonic Stem Cells
Come from fertilized eggs (embryos)
Primary role is to better understand and treat diseases
Can generate all cell types of the human body
The Pros of

for Diseases and Illness
The Cons of
Stem Cell Research
Stem cells are unspecified cells found in multicellular organisms that have the ability to differentiate into other cells and the ability to self-regenerate.
Use the process of Self-Regeneration or Self-Renewal
Can heal and restore skin, bones, cartilage, muscles, nerves and other tissues when injured
Can be manipulated into other body cells including red blood cells, white blood cells, brain cells, live cells, and more
Stem cells are unspecified cells that have the potential to develop into other cells:
Embryonic stem cells- Obtained from embryos that have developed from fertilized eggs through "In-Vitro" fertilization
Adult stem cells- Extracted from various parts of the body such as the brain, bone marrow, blood vessels, skin, teeth, etc.
It means a long individual Life.
Longevity is best thought of as a term for general audiences meaning 'typical length of life' and specific statistical definitions should be clarified when necessary.
People are abusing it to stay younger, which could lead to over population
In July 2001, the House of Representatives voted 265 to 162 to make any human cloning a criminal offense, including cloning to create an embryo for derivation of stem cells rather than to produce a child.
Stem cell research can help determine
what type of stem cell is the best to treat diseases and illness such as:
Spinal cord Injury
In a new study, researchers from Heriot-Watt University in Edinburgh have created a cell printer that spits out living embryonic stem cells.
Occurs when cells die and stop producing dopamine.
Stem cells can be transplanted and begin producing dopamine.
Research will help determine which type of stem cell is necessary.
Spinal Cord Injury
The spinal cord and the brain make up the Central Nervous System (CNS).
Injuries can cause paralysis and loss of sensation.
No treatment available
Transplantation of stem cells into injured spinal cord can replace dead cells, protect cells in injury from further damage, prevents injury from spreading.
A stroke occurs when a vessel in the brain ruptures or is blocked by a blood clot.
80% can be preventable.
Stem cells come from the bone marrow
Stem cells help improve stroke symptoms.
Two patients that previously suffered from strokes showed improving results almost immediately.
Symptoms include: confusion, severe memory loss, stuttering, etc.
No cure available.
Stem cell research has been engaged in mice and seemed to show some benefits.
Stem cells would replace cells killed by the disease.
Alzheimer's patient's skin cells can become potential neurons or brain cells
States are paying more the the federal government.
California is spending more toward stem cell research than any state in the U.S.
Not everyone can afford getting treatments.
In the new study, the cell printer was made from a modified CNC machine (a computer-controlled machining tool) outfitted with two "bio-ink" dispensers: one containing stem cells in a nutrient-rich soup called cell medium and another containing just the medium.
Are there any final questions?
Researchers must not treat any living human as research material for the benefits of others.
Life begins at conception
Stem cell research destroys lives in the hopes that one day there will be a cure
Hi Ikenna :-)
In 1961, Canadian scientists James E. Till and Ernest McCulloch were the first to demonstrate the existence of stem cells in mouse bone marrow.
They defined two main properties of stem cells:
a. Self-renewing of cells
b. Differentiate into more functional cell
