Why do some organs lack the ability to heal?

I ahve heard that when the heart is damages it leaves a permanent scar and that you can't generate heart cells . is that true. If so, why?

It was previously commonly thought that the heart cannot repair itself. However, new research is showing that protein can help repair the heart. http://health.yahoo.com/news/61546

Scarring prevents bloodloss but also somehow prevents regeneration.

Yes, at the moment it does, but in the near future I believe this will be a solved problem.

Guess it's probably just because cardiac muscles don't have satellite cells (meaning they are thus unable to regenerate) which is why it was previously thought that the heart cannot repair itself i guess :shock:

That and the fact that heart cells can not divide

It is because their cells are far-developed or full-developed. More developing cells, so they lose their regeneration capacity. The full-developed cell for instance is neuron. The far-developed cell for instance muscles. And yes broken heart cells cannot be replaced by similar daughter cells because the new ones will affect the mechanism of the well-arranged and well-organized contraction-relaxation of the heart.

hat's why if the organ is fail, it can't be replaced with a new one but only the regeneration of the tissue... :wink:

You are calling yourself 'heartless' ? Where's your heart gone if you don't have one ? :lol: :lol:
