Question 20

STEMCELLSPotentialTherapiesusingStemCells

turn back into different cell type than the resident tissue it was replenishing

Question 22

embryonic stem cell therapies ?

Answer 22

dystrophy, heart disease, and vision/hearing loss.

Question 23

human adult stem cell were used in the first successful bone marrow transplant

Answer 23

in 1968

Question 24

What are Embryonic Stem Cells?

Answer 24

Embryonic stem cells are specialized cells derived from 3-to-5-day-old human embryos that are obtained through in-vitro fertilization in a laboratory setting

Question 25

What are Embryonic Stem Cell Injections?

Answer 25

Embryonic stem cell injections are a form of regenerative medicine. Embryonic stem cells can be injected, implanted, or transplanted into a person to repair dysfunctional, diseased, or injured tissue. The cells can be manipulated to develop into distinct types of cells, such as blood cells, nerve cells, or heart muscle cells. For example, if an individual is suffering from a defective heart muscle, embryonic stem cells can be injected into the defective heart muscle to help in repairing it.

Question 26

Why are Embryonic Stem Cells Known as Specialized Cells?

Answer 26

Embryonic stem cells can change into any type of cell in the body. Under favorable conditions, embryonic stem cells can divide to form specialized cell types with a distinct function, such as heart muscle cells, brain cells, blood cells, or bone cells. No other cells in the human body have the natural ability to produce new cell types as embryonic stem cells

Question 27

How do Embryonic Stem Cell Injections Help Treat Diseases?During an embryonic stem cell injection procedure, stem cells are first developed into specific adult cell types. These matured cells are then used to restore tissue that is damaged due to injury or disease. This type of stem cell injection treatment could be utilized to:

Answer 27

•Produce insulin to treat patients with diabetes •Produce healthy heart muscle cells after a heart attack •Replace neurons damaged by Alzheimer’s disease, Parkinson’s disease, spinal cord injury, or stroke •Treat bone-joint injuries, ligament-tendon injuries, osteoarthritis, cartilage defects •Restore damaged organs or tissues

Question 28

Why is There Such an Interest in Embryonic Stem Cell Injections and Therapy?

Answer 28

There is a great deal of interest in embryonic stem cell injections and stem cell therapy research as they facilitate in understanding: •How diseases occur by observing how stem cells develop into distinct cells in heart muscle, bones, and other organs •Safety and effectiveness of new drugs by testing on stem cells before using them on people. •Generation of healthy cells to replace unhealthy cells by guiding stem cells to become specific cells to repair and regenerate unhealthy or damaged tissues

Question 29

What are the Advantages of Embryonic Stem Cells Over Adult Stem Cells?

Answer 29

Some of the advantages of embryonic stem cells over adult stem cells include: •They contain 10 times more stem cells than adult stem cells from bone marrow. •They rarely contain any infectious diseases and are less likely to be rejected than adult stem cells. •They are free from any abnormalities whereas adult stem cells are likely to contain irregularities due to environmental risk factors such as toxins and errors acquired by the cells through replication. •They have a natural ability to produce new cell types but adult stem cells cannot be manipulated to generate distinct cell types. •The versatility of embryonic stem cells facilitates in regenerating and repairing diseased organs and tissue
