The Effects of Growth on the Cell Diameter, Cell Number and Nucleic Acid Content of the Skeletal Muscles of Chicks

Abstract

Several workers have indicated that the number of cells increases during embryonic growth, but that the multiplication of skeletal muscle fibers does not take place after birth. Since, however, skeletal muscle fibers are multi-nucleated, this result does not eliminate the possibility that nuclear division takes place in the skeletal muscle of the growing chicks.
