Uptake of 45 calcium and 85 strontium by bone in tissue culture.
Embryonic chick calvaria were cultured alive and after killing by various procedures. The uptakes of45Ca and85Sr were measured and it was found that both live and dead calvaria discriminated against strontium in favour of calcium. The discrimination in live bone at 37° was usually higher than that in dead bone or that in live bone cultured at 4°. However, discrimination did not approach the physicochemically predicted level, which suggests that discrimination against strontium is modified by ...Expand abstract
