Zellen und Zelllinien

Zu den bedeutendsten Entwicklungen der biologischen Forschung in den letzten 200 Jahren gehört die Einführung der Zellkultur. Mikrobenkulturen von Bakterien und Hefen in sterilen Medien ermöglichen das selektive Züchten monoklonaler Kolonien von Zellen. Aus diesen Kolonien können z.B. kompetente Zellen für Transformationen gewonnen werden. Bei der Anzucht tierischer Zellen in Wachstumsmedien wird zwischen ex vivo-Kulturen und immortalisierten Zelllinien unterschieden. Ex vivo-Kulturen werden direkt aus Blut oder Organen generiert und besitzen eine begrenzte Lebensdauer. Immortalisierte Zelllinien wie HeLa oder HEK 293T hingegen sind aus Tumorzellen abgeleitet und verfügen über Mutationen, dank derer sie dauerhaft proliferieren können.
