FUNDAMENTAL STUDIES ON SYNOVIAL TISSUE IN TISSUE CULTURE

Tissue Culture Studies

The content of ribo- and desoxyribonucleic acids in chick heart cultures at regular intervals after implanting has been determined both with standard culture medium and with Tyrode's solution alone. With an inadequate medium, both nucleic acids dropped in a consistent manner but ribonucleic acid was affected to a much greater extent. When the medium was adequate for growth, both fractions rose ...

Tissue Culture Studies on Bacterial Hypersensitivity

1. Mononuclear exudative cells, obtained from tuberculous guinea pigs by the intrapleural injection of parowax, exhibited characteristic sensitivity to the toxic action of tuberculin when tested in tissue culture. 2. Experiments with these cells, practically free of body fluids, show conclusively that sensitivity to tuberculin is an inherent characteristic of mesenchymal cells from tuberculous ...

Cartilage Matrix Depletion by Rheumatoid Synovial Cells in Tissue Culture

Articular cartilage fragments were added to monolayer cultures of synovial membrane cells. After 3 wk of incubation, the cartilage fragments were examined histologically for metachromasia and basophilia, and for fluorescent staining using a rabbit antiserum to cartilage protein-polysaccharide. Cartilage incubated with cells derived from rheumatoid synovial membranes showed striking loss of meta...
