Paul Weiss conducted some experiments in 1927 in which his point of
departure was that amphibian lungs don't regenerate. He turned lungs
inside out and slid them onto skinned limbs; amputation stimulated
regeneration. The regenerates had a corium. The regenerate's corium,
Weiss concluded, was produced from the blastema, not the coruim in the
stump -- since the stump didn't have a coruum and, he assumed, lungs
don't regenerate.
Anyway, back in the 1950's, I tried unsuccessfully to find evidence for
or against Weiss's underlying assumption. Vorontsova and Liosner
notwithstanding, I'm still looking.
Here's the Weiss reference (sans accents):
Weiss, P. Die Herkunft der Haut in Extremitatenregenerat (Versuche mit
Hautprothesesen aus Lunge bei Triton cristatus). Roux's Archiv.
109:584-610
1927.
If you ever find a definitive answer, please let me know about it.

This is a follow up to the discussion copied below. I'd appreciate
any explicit and/or more recent references to lung regeneration,
especially in urodeles such as the axolotl? Thanks.
Yours, -Dick Gordon

Sandi and Jill,
I looked in some older literature to check on amphibian lung
regeneration and found mention of some positive results in the axolotl
and in Bufo by a Russian (Solopayev) in the 1950's. I can't find the
exact reference and the work is just mentioned in the book on
regeneration by Vorontsova and Liosner. They make the point that
Weismann examined lung regeneration in the 1890's and reported that it
did not occur, but the newer studies indicate he was wrong. Regeneration
apparently occurs very, very slowly.
I really don't think there have been any more recent studies on lung
regrow at all in the US or Europe, in amphibians or any other animals.

Hello all. We have a question about lung regeneration and we can't find
any references. Anyone out there have any ideas?
