Larue Tissue Cultures of Spermatophytes
Introduction.-The literature concerning the growth of tissues of the higher plants has been reviewed by White2 so recently that it seems unnecessary to repeat it here. Suffice it to say that after a long series of unsuccessful attempts White3 developed a technique by which he was able to secure continuous growth of tomato roots in nutrient solutions. However, in one sense White's results were i...
متن کاملMetabolism of Tissue Cultures
By using radioactive isotopes in tissue cultures, the rate of permeation of substances into cells can be measured independently of concurrent metabolic reactions of these substances. Techniques of obtaining and analyzing data are described. Examples are given using radioactive potassium and phosphorus. Using cultures of chick embryo muscle, turnover time for cell potassium is 6 hours, and for c...
متن کاملCortisone on Tissue Cultures
NUMEROUS recent reports show that cortisone apparently exerts an inhibitory effect, both clinically and in experimental animals, on mesenchymal growth; the evidence on its effect upon epithelial cells is less conclusive. This work has been reviewed by Duke-Elder and Ashton (1951). The object of the experiments here reported is to elucidate the action of cortisone on growth in tissue cultures an...
متن کاملSynovial Tissue Cultures
A B S T R A C T The cellular infiltrate in the deeper layers of the rheumatoid synovium produces a substantial amount of immunoglobulin (Ig)G. Culture supernatants of synovial tissues from 31 patients with rheumatoid arthritis (RA) undergoing joint replacement or synovectomy have been analyzed for the subclass of IgG present. IgG3 was measured by separation with Staphylococcal Protein A chromat...
متن کاملThe Metabolism of Tissue Cultures
1. The metabolism of chick embryo tissues has been followed by analysis of the culture media after various periods of incubation in roller bottles. 2. The initial rate of glucose utilization is increased by increasing glucose in the medium from 100 to 500 mg. per cent. Total glucose used can be increased in the same way or by daily addition of small amounts. Glucose is used in greatest amount w...
