What you say makes good sense, as He does not stick around very well- it would tend to diffuse out through the cell walls.
I once spoke with a fellow involved in the deep sea diving business, and he claimed that vidicon cameras used in the deep habitats used to deteriorate in performance in a matter of days due to in-diffusion from the high pressure He atmosphere. They had to order custom vidicon tubes made of special glasses for which He diffusion was much lower.
