Morphometric Analysis of Particulate Fractions from Rat Liver
The morphological evaluation of fractions isolated by a variety of centrifugation methods has, until recently, been a qualitative one, based essentially on subjective impressions of small samples whose representativeness was not known. The lack of quantitative information about components of these fractions severely limited the usefulness of these morphologic data and made correlation with biochemical results rather difficult. In response to this situation, Baudhuin et al., and later Baudhuin and Berthet presented a method which circumvented previous problems and gave quantitative results directly comparable to those obtained by other methods. This method has been used in recent investigations concerned with the role of the lysosomal system in cellular autophagy carried out in this laboratory.
