Alteration in Fibroblasts Treated with Steroids in a Perfusion Chamber.

Abstract
The response of chick and mouse fibroblasts to adrenal and non-adrenal steroids was studied in a perfusion chamber. Desoxycorticosterone and steroids closely related to it caused great increase in the size of the cells. The nucleus and heterochromatic material within the nucleus showed particularly great increase in volume. There was an increase in the number of mitochondria and a tendency to lay down large numbers of fibers.
