Do all types of human tissue regenerate?

[Alfred001]

I'm having my small intestine biopsied soon and thinking about it got me curious about whether the small chunk they will be taking out will regenerate?

 

I seem to recall reading that all kinds of human tissue regenerate, is that true? Obviously if someone gets a large enough cut they need stitches for it to heal, if they have their arm amputated another one won't grow, but does the statement that all types of tissue regenerate hold true when it comes to tiny nicks like biopsy type nicks?

There's a difference between "regeneration" and growing back tissue. Your chunk of your intestine will grow back, while an amputated arm won't. Unlike salamanders, we lose the kind of embryonic regeneration we had in the womb that would let us actually regenerate a lost limb, various tissues, bone and all.

 

Apparently we do have all the right apparatus to induce embryonic cell regeneration just like the salamander, but we lose the ability shortly before birth. We're making strides towards being able to switch this back on. Imagine regrowing teeth your whole life.

Of course, faster with proper nutrition. ie. avoiding processed food.

Any evidence for this claim,. considering processed is quite a broad term.

Eat a head of lettuce per day for a week and then look at your nails at the end of the week. Then decide for yourself.

[Ringer]

That's not a very scientific way to go about it. What if I don't clean my nails that week, what if I didn't clean my nails the week before? What is in lettuce that would increase keratin production? What if the lettuce is processed? etc, etc, etc.

Since when do nails grow from the tips?

*Keep in mind that different tissues have different characteristics.. for example neurons don't 'grow back' which is why degenerative diseases are so damaging, also tendons and ligaments usually have a low blood supply which makes it harder for them to repair..

Eat raw potatoes for a week and see if you still think processing is a bad idea.

If that doesn't change your mind, have a go at raw cassava or cashew nuts.

Raw meat is not generally considered a healthy option.

 

 

Most human tissue will regenerate to at least some degree.

Teeth don't.

The small cuts made by things like biopsy samples do regenerate.

I believe the liver is best at it.But your heart or brain cannot.Even small brain damagae or small damage to the heart the body cannot repair it self same with the spine.

Do not exactly know what do you mean by regenerate.

Everything in the human body can heal itself except the heart and brain.
