bio unit 2 2014 june question

can someone plz explain the question i sent.. the answer is pluripotent .. but the question says that the stem cell is extracted from the human heart cell and any stem cells found in the human body is no longer pluripotent cos they cant technically give rise to allll the body cells . theyre only capable of diffrentiating into a limited number of cell types so theyre multipotent so based on this i picked cardiopotent as i asumed its a form of multipotency but why is it wrong

Even when cell are said to be SPECIALIZED, cells have the PROPERTY OF POTENCY so they remain Unspecialzed and divided ..
So always, there are some amount of cells that are PLURIPOTENT

yesss true. but their they are specilazed to a limited number of cells.. pluripotent cells which are present in the embryo specilaize into alll body cells... so how are the stem cells extracted from the body pluripotent .. they cant be :frown:

Read the question.....CAREFULLY
It does not say anything here about specialisation.

PLURIPOTENT cells can give rise to all cell types EXCEPT A NEW EMBRYO...so these CELLS ARE NOT SPECIALIZED

TOTIpOTENT cells can even make a whole embryo

since the cell is taken from the body it is no longer pluripotent :frown:

why not??
They divide while maintaining the undifferenciated state.
They have NO HAYFLICK LIMIT

i mean thy cannot divide into every single cell type so theyre multipotent.. did u see what i sent

I know the difference dude...
But understand the question and ADOPT to the question
According to your question, it is PLURIPOTENT as they have not give a answer as MULTIPOTENT
