The nature and content of lytic bodies and the localization of acid phosphatase (AcPase)
activity were investigated in mammotrophic hormone-producing cells (MT) from rat anterior …

Cell junctions have been investigated in the amphibian epidermis, a stratified squamous
epithelium, and compared to those described previously in simple columnar epithelia of …

The glomerular basement membrane was subjected to digestion with specific enzymes to
