AI Thread Summary
The discussion centers on the diffusion of molecules from the endothelium of arteries to the surrounding muscle cells. It raises the question of whether muscle cells have similar membrane proteins as endothelial cells, which would facilitate this diffusion process. The mention of capillaries highlights their unique structure, consisting solely of endothelium, which may play a role in the diffusion dynamics being questioned. The inquiry reflects a curiosity about the cellular mechanisms involved in molecular transport between these two types of cells.

Hello guys,

This might be a stupid question but artery has an inner endothelium and muscle outside. So if molecules diffuse out from the endothelium do they diffuse out of the muscle cells as well. How is that done, do muscle cells have the same membrane proteins as endothelium? Thanks :smile:

Oh right I forgot about capillary which is just one endothelium. Sorry guys!

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
