Missing parts? Salamander regeneration secret revealed
Live science ^ | 5-20-2013 | Tanya Lewis

Salamanders can regrow entire limbs and regenerate parts of major organs, an ability that relies on their immune systems, research now shows.

A study of the axolotl, an aquatic salamander, reveals that immune cells called macrophages are critical in the early stages of regenerating lost limbs. Wiping out these cells permanently prevented regeneration and led to tissue scarring. The findings hint at possible strategies for tissue repair in humans.

I’ll take the one that will screw with my mind.

I can’t stand dour people in a hospital setting.

A few years after my mom died, I went through a box she had in her closet (yes, it took a few years) anyway, I found a hand-made card from a 8 year old me that I made for her when she was in the hospital with ovarian cancer back in the sixties.

It said “ Have A Happy Operation”. LOL!

I had no idea back then. But she kept it.

Beats the first emergency doc that did my initial endoscope after my accident, and I heard him say as they were putting my out "Oy, he's f****d."

After my accident, and the 2 days in a coma, they moved me to regular ICU out of trauma care and I was alert and mentally functional until they mashed that little button.

Nurse came in and said my Mom had driven all the way to New Mexico because they were told I was going to die. And Mom wanted to see me.

I told the nurse to give me a minute, rolled my head to the side, crossed my eyes, and started drooling.

The nurse actually slapped my shoulder and called me an unkind name as she was laughing.

Hey. Being serious or whiney doesn't change the outcome. That's in God's Hands.

And laughter is the best medicine.

LOL!

I never thought about it from the patients angle.

That was hilarious!

If, may God Forbid, am ever in the hospital, I’m doing something just like that!

During that event and aftermath, the only unkind thing I did was when they had me strapped down and tubes down my throat and I was just coming out of the coma, and I woke up to CNN on the television.

I thought I had missed my destination and gone to Hell for a confused moment.

When I finally got their attention, I signalled that I wanted a pencil and they held a pad and I scrawled "TV EVIL!!!!" and the doc looked weird at me and told the nurse to turn off the TV. My brother laughed when the doc told him about it.

Otherwise, I tried to take as good care of the care staff as they took care of me. Being a problem patient wasn't going to get me better care, and they didn't deserve to get lashed at because I didn't feel well.

It worked for me.

Interesting if it can be applied to humans.

I wouldn't mind having a set of teef, a kidney and my spleen back, if they can make it work.

Tv Evil! LOL.

Jokes aside, you don’t sound like a problem patient at all. It seemed to me the staff already knew you a bit before you joked around..

I remember seeing stories about this but think it was the toe next to the big toe.

If you take the big toe there is serious implications to mobility/walking gate. Now if they took it off what used to be your foot, then mobility is probably already affected.

Bizarrely, I have ‘regrown’ finger tips, a frontal lobe, an entire ankle bone and whole top of my hand which were sheared off by a horse’s hooves.

There are virtually no scars anywhere that indicate I’ve ever been injured.

And you thought my user name was just “cute”.

8:)

One of my snake acquaintances lost his thumb to a Rattler bite and now has a big toe where it used to be.

If he’d bother to keep the nail trimmed, it might not look so freaky.

Yes, I’ve always thought your user name was cute,
but no, I never thought it was just cute.

You’d think he’d leave your personal life out of it and fix your medical problem...

I'm jealous. I've live an... 'exciting' life in a lot of ways, and I'm a virtual canvas of abstract art done in scar tissue.

Some folks look away when I take off my shirt.

Scars are interesting.

You must run into a lot of sissies.
