摘要：Somatic cell hybrids have been prepared at high frequency between the rat muscle cell line L6 and human fetal muscle cells. The hybrid cells express several human gene products including an antigen, 12E7, controlled by the human X chromosome, Thy-1, and several human isoenzymes. In addition, one clone (37-11) expresses a human muscle-specific surface antigen (5.1 H11) and, under appropriate conditions, can be induced to form myotubes. Upon myotube formation, this clone switches on the production of the human muscle-specific creatine kinase (ATP:creatine N-phosphotransferase, EC 2.7.3.2 ) M subunit. This is an example of developmental regulation of human muscle-specific genes in somatic cell hybrids.
