Skip to comments.Missing parts? Salamander regeneration secret revealed
Posted on 05/20/2013 7:20:34 PM PDT by Redcitizen
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.

Beat me to it!
My brother had his thumb cut off from an accident at a construction site. He was up on a ladder handling some cables (he’s an electrician) and, due to someone dropping something, the cables sped loose and took his thumb right with it.
I gave him the thumbs up when I saw him that day.
i saw a thing where a guy lost his thumb in an accident then lost his foot in another but they put his big toe where his thumb used to be
“i saw a thing where a guy lost his thumb in an accident then lost his foot in another but they put his big toe where his thumb used to be”
I seem to remember something like that. I told him that was the solution to his missing-thumb problem too.
Me and my man...atee.
are you saying it would save huge manatee and whales all in one breath
I see a family resemblance...
Was his name... Tony?
So did he get his thumb reattached? LOL at giving him thumbs up.
By a nose!
A friend of mines nephew was working on a cat and ended up sticking his hand in the fan. They are going to put his big toe where his thumb was.
Maybe this information can be combined with scaffolding technology.
Reminds. Me of when my friend (and employer) got in an awful motorcycle wreck. He didn’t know what from where for an extended period.
Anyway, they had a wax board in his room “ your nurses name is ______’ your doctors name is ______”.
The fun was Today’s date is______”
One of his daughters, , to my chagrin at the time, used to wait until he nodded off for a few minutes, then change the date. .....
It took me awhile to see the humor, but damn...that was LOL stuff.
Nah, his name is Larry. They couldn’t reattach the thumb. It was too messed up. He’s still working though. He had previously just gotten a promotion, and so now they sit him at a desk organizing and planning, and when he goes out he still manages to make it work. He didn’t sue.
His boss later told him “Well, at least now you can’t sit around with your thumb up your ***”! A friend of his also said “Hey, man, I wanna play thumb war with you!” The thumb incident led to great fun!
LOL, that does sound fun!
I’ve since thought, who would I rather have visit me in the hospital—the dour serious relative, or one that will screw with my mind a bit....
shoulda gave him a hand...
In other news his hands finally fit real nice in oven mitts...
I’ll take the one that will screw with my mind.
I can’t stand dour people in a hospital setting.
“In other news his hands finally fit real nice in oven mitts...”
LOL I am going to tell him that!
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.
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.
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!
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.
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”.
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.
Anything is possible, but without your big toe you cannot walk with that foot.
I cannot imagine giving up the ability to walk unaided for a missing thumb.
But then, I've seen just about everything lately, so...
I know a guy who put his head where his ass is, and became President.
Regeneration? That axolotl one’s immune system...
I’ve regrown my brain, twice.
And some cannot look away.
Or vice versa.
I live in a world full of geckos, who constantly lose tails to each other, my cats, doors, whatever.
Since a lot of them prefer to stay in their own little patch of turf, it is fascinating to see the tails grow back. They start out very stubby, but extend out and eventually achieve the same shape as the original. Only the coloring often does not match. Maybe they lost the color chip?
that happens a lot
