On DMSO and its infleunce on Collagen and smooth muscle:
Prolonged exposure of cultured arterial smooth muscle cells to 1% dimethyl sulfoxide (DMSO) resulted in a remarkable increase in cytoplasmic microtubules and an appearance of bundle-like aggregates of microtubules associated with ribosomes

Microtubules form part of the cytoskeleton that gives structure and shape to a cell, serve as conveyor belts moving other organelles through the cytoplasm, are the major components of cilia and flagella,
and participate in the formation of spindle fibers during cell division (mitosis). Microtubules can function individually or join with other proteins
to create larger structures (e.g. cilia). These filaments are composed of linear polymers of tubulin, which are globular proteins, and can increase or decease in length by adding or removing tubulin proteins.
These straight, hollow
cylinders are found throughout the cytoplasm of all eukaryotic cells (prokaryotes don't have them) and perform a number of functions.

As I understand it till now, the microtobules are important to the cytoskeleton which also is important for the building of collagen structures.
This could mean that DMSO helps in building new collagen structures. These should be of the healthy kind which we might ensure with adequate enzymes and vitamins.
Tough this is only my amateur understanding.

Oner point that worries me a bit is the following quote:
[

"
The growth of bovine aortic smooth muscle and endothelial cells was studied after exposure to dimethyl sulfoxide (DMSO) or its major metabolite, dimethyl sulfone (DMSO2). Both compounds caused a dose-dependent
inhibition of cell growth as determined by [3H]thymidine incorporation and by counting the number of cells with time of exposure in culture.
..
It is concluded that the growth of smooth muscle cells was similarly inhibited by DMSO and DMSO2, but that smooth muscle cells were more susceptible than endothelial cells to the growth inhibitory effects of these compounds."
-- This states that bovine smooth muscle growth is inhibited under the influence of DMSO...

________
In a follow up study:
"Inhibitory effect of dimethyl sulfoxide on the proliferation of cultured arterial smooth muscle cells: relationship to the cytoplasmic microtubules."
..
"Our preliminary study has shown that dimethyl sulfoxide (DMSO) has an inhibitory effect on the proliferation of cultured arterial smooth muscle cells and promotes phenotypic modulation from the synthetic state to the contractile state. In the present study we have examined the effect of DMSO with special attention to relationship between cell growth and cytoplasmic microtubules."
..
" These results suggest that DMSO inhibits DNA synthesis of cultured smooth muscle cells by stabilizing cytoplasmic microtubules."
_________________________
This might mean that using DMSO to expand and heal collagen is very usefull while it isnt for smooth muscle.
This might give some connection to the TGC Theory which states simplified that you have to concentrate on smooth muscle exercises or Tunica exercises to grow the whole dick. (smooth muscle fills the space that the tunica gives)
-------
This study on the other hand sounds good for smooth muscles.

"Synthetic activity of collagen types was examined in cultured arterial smooth muscle cells during modulation from synthetic to contractile phenotype by treatment with dimethyl sulfoxide (DMSO). Smooth muscle cells of rabbit thoracic aorta cultured with a 1% supplement of DMSO for 8 days (DMSO group) predominantly exhibited cellular features of the contractile type with abundant microfilaments and a distinct basement membrane. "
..
"Type analysis of the collagenous protein by SDS-PAGE and subsequent fluorography disclosed a markedly
increased ratio of type IV/I collagen*1 and a slightly increased type V/I collagen ratio, as compared with those of controls. A decrease of type III collagen production in DMSO-treated cells probably due to their lower cell density was also recognized"
...
(*1 does this mean the type IV or the typoe I did go up?)
___________

-> DMSO has influence in upping type IV collagen which we dont want(we want type 1 or two)
quote:
"Such an enhancement of type IV collagen synthesis appears to be expressed as a result of the phenotypic changes of smooth muscle cells to the contractile state modulated by DMSO."
_________
Well I hope someone can follow my thoughts and has some ideas..
DMSO sure helps but I want to find out when and where it helps best. If it inhibits smooth muscle grow then it might not be usefull for everyday application.
