A formação de protuberâncias na superfície de uma célula é chamada "zeiose", do antigo termo grego para água fervente, mas as protuberâncias em si são agora chamadas bolhas. As bolhas podem ser a consequência do dano molecular direto ou indireto que prejudica a estruturação do citoesqueleto.

Os métodos sofisticados usados atualmente para cultura de células representam importante avanço nas ciências biológicas. Os cientistas hoje podem investigar não apenas órgãos ou organismos completos, mas a bioquímica e o comportamento de células isoladas e tipos de células. As análises bioquímicas de culturas em crescimento podem investigar, por exemplo, os mecanismos de duplicação celular, comunicação célula-a-célula, produção de energia celular ou reparo do DNA. Além disso, o desenvolvimento de poderosos microscópicos eletrônicos permite o estudo da morfologia celular, a forma das células isoladas.
