Elastase involvement in extracellular and intracellular collagen degradation during postpartum involution of the uterus

Bull Exp Biol Med. 2003 Aug;136(2):206-8. doi: 10.1023/a:1026395613444.


The location of elastase in rat uterus during its postpartum involution was studied by electron histochemical method. Intense extracellular activity of the enzyme was detected: the reaction product was found on the cytolemma of smooth-muscle cells and, to a lesser extent, on the cytolemma of macrophages and fibroblasts and on adjacent collagen fibrils. The reaction product was also found in vacuoles with collagen in macrophages and fibroblasts.
