3mm Punch Biopsy

[gumbo]

I work in a lab that analyzes nerve fibers and wound healing. We routinely take shots under macro to analyze the rate of clotting, scabbing, and circumferential change to a circular wound 3mm wound.
Here is one of my thousands of wound images.

We also do stereo histology of 1/50th slices of these wounds, and stain for nerve fibers, both autonomic and sensory. I'll try to post one later.

so you cut the 3mm wound yourselves, out of interest with what?

 

[Fnord5]

Using this.

Do you have people that volunteer?

I had an 8mm punch biopsy on my cheek. Then pinched and stitched. The plug was fairly interesting to see... Now I just have a 1cm scar.

I hope you compensate your test subjects!

Our biopsy method is much more shallow than that. They are 3x1mm.
We are looking at interepidermal nerve fibers, not muscular tissue.

Here is a nice shot of some sweat glands wrapped around a hair follicle. These are actually mine, it was when we were working out the kinks of the new camera/scope. I have plenty of small scars on my legs from self-biopsies

Green is stained fluorescent VI Protein, you can see the nerve fibers attached to the glands themselves.
Yes. It's real.

I have had 6 punch biopsys for a clinical study involving psoriasis the ones from my legs have healed nicely over the years the ones from my midsection look like a vampire bite OO.
