Factors influencing the growth of normal and malignant cells in fluid culture media

摘要: In a former communication (Ludford, 1933,) attention has been directed to differences in the growth of mouse tumours plasma and serum. With aim elucidating tire significance these differences, further series experiments have carried out, which brought light new facts necessitating revision my conclusions, as well those previous investigators who worked with fluid media, At same time insight gained into complexity factors influence It found that different strains transplantable exhibit individual when grown serum, even strain show marked from time. Also, both. type its extent are influenced by source serum is derived, is, whether it homologous or heterologous. describing will be necessary therefore deal separately. Concerning this tumour I am unable add anything account published paper 1933). Neither nor rat possible yet obtain good outgrowths sarcoma cells. Pure diluted serum; without, embryo extract; young old rats, male female, both pregnant non-pregnant; also types cover slips all tried without influencing growth.
