can someone.give a brief explanation.of multipotent stem cells? i read they are ready diffrentiated?

Posted from TSR Mobile

does anyone know where i can get the soft copy of biology revision guide book from?

you only need to know about totipotent and pluripotent stem cells.

multipotent stem cells can develop into many cells, except a few such as extra-embryonic cells, blood cells, etc

i want to check with u:
pluripotent can gv rise to most cell types and totipotent to all cell types...
ok now cells in a human body are pluripotent besides liver cells?
and embryonic cells are totipotent ryt?
I hate this section tbh....so check it for me

yes and yes
Nope, human body cells are differentiated apart from pluripotent stem cells found in places such as bone marrow
yes

not sure if I know which revision guide you're talking about

ok gv me 3 ethics related to stem cells...
and for e.g if they asked us why we can't replace a damaged liver using stem cell? its possible ryt? maybe coz of ethics and possible rejection/cancer ?

theres the issue of cloning, misuse of stem cells, the idea that most embyonic stem cells occur due to IVF, they can't give concent to research, they will get discarded if not used and their right to life removed

risk of rejection, mutations, difficult to specialise cells, surgical risks

Do you guys think that its gonna be as awful as unit 1? or nice cause unit 1 was hard?

thanks man! i thnk we almost covered everything regarding stem cells, isn't it?
one more question...what is cloning?
