title: Development of a diploid cell line from fetal calf lung for virus vaccine production.
abstract: Details of isolation and replication of a fetal calf diploid cell (FCDC) is given. From the karyological point of view, the fairly large number of chromosomes existing in metaphase spreads made counting rather tedious. Lack of practical classification was another problem which made reference to individual chromosomes difficult. By increasing the population doubling of this cell, a tendency of telocentric chromosomes to undergo centric fusion was observed. Susceptibility of FCDC to different viruses is described.
