BB creatine kinase and myogenic differentiation. Immunocytochemical identification of a distinct precursor compartment in the chicken skeletal myogenic lineage. 1984

M M Robinson, and L S Quinn, and M Nameroff

Antisera specific for the B monomer of creatine kinase (B-CK), the M monomer of creatine kinase (M-CK), and muscle-specific myosin heavy chain (MHC) were used to investigate the biochemical characteristics of individual cells in primary myogenic cultures. Through the use of immunocytochemical techniques, in conjunction with 3H-thymidine autoradiography, it was determined that (1) all of the terminally differentiated myoblasts contained B-CK in addition to M-CK and MHC, (2) none of the cycling cells contained M-CK or MHC, (3) a fraction (7.5%) of the cycling cells contained B-CK, and (4) the cycling, B-CK positive cells divided once, and only once, and produced two terminally differentiated myoblasts. These results indicate that myogenic precursors in vitro are a phenotypically heterogeneous cell population and that the appearance of B-CK in cycling myogenic cells is a biochemical manifestation of a distinct precursor compartment in the chicken skeletal myogenic lineage.

D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick
D003402	Creatine Kinase	A transferase that catalyzes formation of PHOSPHOCREATINE from ATP + CREATINE. The reaction stores ATP energy as phosphocreatine. Three cytoplasmic ISOENZYMES have been identified in human tissues: the MM type from SKELETAL MUSCLE, the MB type from myocardial tissue and the BB type from nervous tissue as well as a mitochondrial isoenzyme. Macro-creatine kinase refers to creatine kinase complexed with other serum proteins.
