FIG. 11. Electropherograms of L D H isozymes reproduced at various stages of
cultivation of differentiating kidney mesenchyme in organ culture (upper part of the
figure). In nondifTerentiating explants n o such enzyme shift was observed. The ontogeny of the L D H isozyme pattern in developing kidney in vivo is depicted in the
lower part. Electropherograms drawn one below the other correspond on the time
scale.
