Abstract
Summary
When 10-day-old chick embryo femora were cultured for 2 days in medium containing methyl or propyl paraben, there resulted an increase in dry weight as compared with femora cultured in the control medium. The methyl paraben concentrations found to stimulate growth were 10-5 and 10-6 M. Propyl paraben stimulated at 10-5 to 10-7 M. The effects of the two were not additive. It is suggested that these compounds may stabilize lysosomes.
