Nanofiber Spheres Carrying Cells Injected Into Wounds to Grow Tissue

Quote:
ScienceDaily (Apr. 17, 2011) — For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, but the cells live on to form new tissue.

A new approach to inject cells to form new tissues. Of course, we are still faced with the problem of whether or not the cells will be rejected (immune response), but we are one small step closer to getting them into the damaged tissue.

All they have to do is take one or more cells from your body and inject it in. Doctors once had this man who had almost no cartilage in his knee so they took some cartilage from another part of his body and put it in his knee. His body accepted it because it recognized it and took care of it until he had all the cartilage he needed at his knee.

That would be sweet if this was mainstream. Would be even better if doctors could grow your cartilage in a lab. biggrin.gif

Not all cells have this ability wink.gif

I think you may be thinking about Adult Stem Cells...

I think growing it in a lab then having it surgically implanted would be much more painful then just having it grow naturally.

The idea might be to take our own cells, urge them to replicate via administration of growth factors in vitro, then package them and administer them with the nano-spheres.

Though I'm at a bit of a loss as to why we can't simply inject the cells. Why do we need the nano-spheres? I mean, I'm not seeing how the spheres simulate a cell's natural living environment better than, say... my own body already does. Oh well.

Wow, I immediately thought of the cutscenes in Crysis 2, with those nano-viruses and the containing nanofiber weaves. biggrin.gif

The next step they need to get down is growing out own cells cheaply and quickly. Combined and you get epic heals.

Think back at when you were developing inside your mother's whomb wink.gif

Look into blastocyst if you don't know what I am referring too tongue.gif
