The number of Rous viral genomes in the cellular DNA from two subclones (RS2/3, RS2/6) derived from the same clone of hamster BHK-21 cells transformed by Rous sarcoma virus was determined by hybridization with viral complementary DNA made in vitro, and the capacity of the cellular DNA to infect (transfect) chicken embryo fibroblasts was compared before and after shearing this DNA to about the s...
PURPOSE The chicken embryo lens is a classical model system for developmental and cell biology studies. To understand the molecular mechanisms that underlie the morphological changes that occur during lens development, it is important to develop an effective gene transfer method that permits the analysis of gene functions in vivo. In ovo electroporation has been successfully used for introducin...
The expression of the myogenic regulatory factors (MRFs), Myf5, MyoD, myogenin (Mgn) and MRF4 have been analysed during the development of chicken embryo somites and limbs. In somites, Myf5 is expressed first in somites and paraxial mesoderm at HH stage 9 followed by MyoD at HH stage 12, and Mgn and MRF4 at HH stage 14. In older somites, Myf5 and MyoD are also expressed in the ventrally extendi...
