(m) uses of stem cells in research and medicne

How can stem cells be used to treat heart diesease

When muscle tissue is damaged due to heart attack

Some success already

What diabetes can it help treat

TYPE 1 DIABETES

Body destroys insulin producing cells in pancreas

What type of degeneration can it help treat and how?

MASCULAR DEGENERATION

responsible for causing blindness in elderly and diabetics

Currently research is being done of stem cell treatment for this

What already is stem cells being used to treat?

Burns

S.c grown on biodegradable meshes can produce new skin

What type of disease can stem cells be used for

Neurological diseases

Alzheimer’s disease

Parkinson’s disease (caused by death of dopamine)

What law was changed slightly to do with embryos

Used to be donated but now it’s legal to be made in the lab as a source of stem cells

What moral objections are there

Removal of embryos can be the destruction of embryos

Life begins at conception = murder

What overcomes the moral objection but what is downside of it?

Use of umbilical cord stem cells

However these are multi potent not pluripotent like embryonic stem cells

So restricts the usefulness

What else can be used apart from embryonic stem cell and umbilical. Cod ?

What is downside?

Adult stem cell

But they dont divide as well um.stem cell

More likely to have mutations

What is iPSC s

Induced pluripotent stem cells

These are adult stem cells that are genetically modified to act like embryonic stem cells and are pluripotent

What is the advantage to using plant stem cells

The use of plant stem cells dont raise the same ethical issues of animal cells
