These experiments showed that phloridzin must pass the placenta, and make it highly probable that the physiological fatty infiltration is not derived from the tissue fat but some other source. Perhaps this other source is that postulated by Wesson in his explanation of the increasing fat-content of the embryonic body and the impermeability of the placenta to fatty acids. One of the statements which has entered the literature without much justification is that embryonic cells (and carcinoma cells too) will not show fatty infiltration when treated with phosphorus. This was said to be the case by Hess & Saxl who made in vitro experiments on guinea-pig and rabbit tissues (liver and kidney). Some years later.
