  <dc:description>&lt;p&gt;&lt;span&gt;A line of fibroblast cells has been established from tongue tissue of the bullfrog (&lt;/span&gt;&lt;i&gt;Rana catesbeiana&lt;/i&gt;&lt;span&gt;). The cells are near-triploid and were subcultured 57 times during the 2⅔ years of their existence. Some of their characteristics are described.&lt;/span&gt;&lt;/p&gt;</dc:description>
