good so that’s what we’re trying to do

good so that’s what we’re trying to do in the lab now we would never be able to

we could find the active ingredient we

we could find the active ingredient we might be able to use it and that’s what

might be able to use it and that’s what

might be able to use it and that’s what I was able to do we identified the

I was able to do we identified the

I was able to do we identified the active ingredient that causes wound

active ingredient that causes wound

active ingredient that causes wound healing in worms spirit and it’s named

this is fascinating to study it makes it

this is fascinating to study it makes it really expensive really tricky and

really expensive really tricky and

really expensive really tricky and really messy to make so we’d never be

really messy to make so we’d never be

really messy to make so we’d never be able to turn it into a pharmaceutical

able to turn it into a pharmaceutical

able to turn it into a pharmaceutical but maybe we don’t need the whole

but maybe we don’t need the whole

but maybe we don’t need the whole molecule maybe we just need a little bit

molecule maybe we just need a little bit

molecule maybe we just need a little bit of it and that’s what we tested in the

of it and that’s what we tested in the

of it and that’s what we tested in the lab a whole range of different bits of

lab a whole range of different bits of

lab a whole range of different bits of it in the lab we’re able to make it with

it in the lab we’re able to make it with

it in the lab we’re able to make it with amino acids and gluing them together bit

at a time to make it synthetically and thus allowed us to make these various

thus allowed us to make these various

thus allowed us to make these various different active molecules to test in

different active molecules to test in

different active molecules to test in our studies so then we ran out tests

our studies so then we ran out tests

our studies so then we ran out tests through some healing mouse winding tests

through some healing mouse winding tests

through some healing mouse winding tests here’s the mice or anesthetized and kept

this over days and watch those wounds

this over days and watch those wounds close and we measure how long it takes

close and we measure how long it takes

close and we measure how long it takes to get to 80% closure so here’s a

to get to 80% closure so here’s a

to get to 80% closure so here’s a baseline healing rate of 8.6 days of our
