Abstract:
:The purpose of this study is to visualize topographical changes of serum proteins, albumin and immunoglobulin, passing through mouse glomerular capillary loops and their reabsorption in renal proximal tubules by immunohistochemistry in combination with our "in vivo cryotechnique". The "in vivo cryotechnique" was performed on left mouse kidneys under normotensive, experimentally acute hypertensive and heart-arrest conditions. The cryofixed tissues by the technique were routinely processed for freeze-substitution. Serial deparaffinized sections were stained with hematoxylin-eosine and immunostained with anti-mouse albumin, immunoglobulin G (IgG), kappa or lambda light chain and IgG1 heavy chain antibodies. Under the normotensive and heart-arrest conditions, albumin and IgG were clearly immunolocalized in blood vessels and slightly in apical cytoplasmic parts of some proximal tubules. Under the acute hypertensive condition, the albumin and kappa or lambda light chains, but not IgG1 heavy chain, were strongly immunolocalized in the apical cytoplasm of almost all proximal tubules. This study is the first in vivo visualization for glomerular passage of serum proteins and their transtubular absorption. Thus, the "in vivo cryotechnique" with freeze-substitution can be used for clarifying not only the functional morphology of living animal cells, but also in situ immunohistochemical localization of their components.
