A principle of regulation of matrix metalloproteinase (MMP) activity has been introduced as the cysteine-switch mechanism of activation ( Springman et al. 1990 ). According to this mechanism, a critical Cys residue found in the auto-inhibitory propep

In the human stomach, the oxyntic epithelium includes numerous tubular invaginations consisting of short pits opening into long glands. The pit is lined by pit cells, whereas the gland is composed of three regions: the base, containing zymogenic cell

In the transformation of the cartilaginous epiphysis into bone, the first indication of change in the surfaces destined for resorption is the cleavage of aggrecan core protein by unidentified matrix metalloproteinases (MMPs) (Lee et al., this issue).

The formation of a secondary ossification center in the cartilaginous epiphysis of long bones requires the excavation of canals and marrow space and, therefore, the resorption of cartilage. On the assumption that its resorption requires the lysis of

Since we had subdivided the cell cycle into 11 stages--four for mitosis and seven for the interphase--and since we had experience in detecting DNA in the electron microscope (EN) by the osmium-amine procedure of Cogliati and Gauthier (Compt. Rend. Ac

The secretions of the mammalian stomach are produced by cells present in invaginations of the epithelium, which in the mouse are straight tubules referred to as "zymogenic units." These units comprise four regions, namely pit, isthmus, neck, and base

The Feulgen reaction has been utilized to localize DNA in nuclei throughout the cycle of mouse duodenal crypt cells using Epon-embedded 1 micron thick sections. The observed changes indicate that the 12.3 h long mitotic cycle of these cells can be su

Entero-endocrine cells and the rare cells named caveolated or brush cells have been examined in light microscopic radioautographs of the mouse corpus after various periods of continuous 3H-thymidine infusion. Moreover a search for immature forms and
