I can't see a thing in there except for the air cell. I'm on day 8 and thought "possibly" I could see some veins, but not positive. Everything looks dark and it's fairly porous. I've tried using different light sources, but so far haven't had any luck. I plan on giving it more time, but I'm at a loss and not quite sure what else to try.
