The transcripts of the Grand Jury testimonies about the shooting of unarmed teenager Michael Brown by Ferguson police officer Darren Wilson.

Urn, I guess I'll preface it with this. Within a skin sample, there's a variety of cellular elements meaning different types of cells that are present within our bodies and, urn, at times there is a cell called melanocyte. It's our cell that's responsible for producing pigment.

That particular cell when it makes its pigment, it kind of gives it away to another cell type, which is called a keratinocyte. In this particular cell at the junction between the dermis where I was telling you guys that connective tissue layer is, it's at the bottom part of the legitimate skin layer.

These two cells are kind of in contact with each other and they communicate. So the melanocyte makes the pigment, gives it to the keratinocyte, which kind of absorbs it and then it kind of allows skin to kind of display its pigmented characteristics.

And the particular sample that I received to look at independently, there are keratinocytes there, but they are not picking up a lot of pigment.

So in my personal opinion, this particular skin fragment has to be from an area of the skin that is not highly pigmented. There is a few places on the body, especially for someone whose skin is of a pigmented nature, where you can have a more likely pigmented type skin.

And I'd like to show you, if you look on the back side of my hand here, if I looked under a scope on a piece of my skin under the microscope, I would see more pigmented keratinocytes present, but on this side of my hand it is more lightly pigmented, they are not going to be as prominent or being as significant.

So saying all of that, the fact that that's specimen that I do have, there aren't a lot of pigmented keratinocytes. So I suppose that this fragment is coming from an area where the skin is lightly pigmented.
