August 1920 in Roanoke im US-Bundesstaat Virginia geboren. Sie wuchs in ärmlichen Verhältnissen auf. Nachdem ihre Mutter bei der Geburt ihres zehnten Kindes gestorben war, zog ihr Vater mit den Kindern zu Verwandten auf eine Tabakplantage in Clover. Henriettas Familiengeschichte war eng mit der Geschichte der Sklaverei in den USA verbunden. Ihre Vorfahren hatten auf der Tabakplantage als versklavte Menschen gearbeitet. Zu ihren Vorfahren gehörte auch der Plantagenbesitzer Albert Lacks, der mehrere Kinder mit einer versklavten Frau hatte. Nach der Abschaffung der Sklaverei vermachte er einigen seiner schwarzen Nachkommen Land – darunter Henriettas Großvater."), ("p", "Henrietta teilte sich als Kind ein Zimmer mit ihrem Cousin David \"Day\" Lacks. Als sie 14 Jahre alt war, bekam sie das erste gemeinsame Kind. Wenige Jahre nach der Geburt des zweiten Kindes heirateten die beiden. Insgesamt bekamen sie fünf Kinder. Wie viele andere Familien ihrer Zeit führten sie ein einfaches Leben und arbeiteten hart. Obwohl die Sklaverei längst abgeschafft war, prägten Rassentrennung und soziale Ungleichheit das Leben schwarzer Amerikaner noch immer. Auch Henrietta sollte das später erfahren."), ("p", "Aus den ersten beiden Buchstaben ihres Vor- und Nachnamens entstand später der Name einer Zelllinie, die fast jeder Biologe kennt: HeLa."), ("h", "Wie kamen ihre Zellen ins Labor?"), ("p", "Als Henrietta Anfang 1951, nach der Geburt ihres fünften Kindes, wegen ungewöhnlicher Blutungen ins Krankenhaus ging, ahnte sie nicht, dass dieser Arztbesuch Medizin-Geschichte schreiben würde."), ("p", "Von ihrem Hausarzt wurde sie zur Untersuchung an das Johns Hopkins Hospital in Baltimore überwiesen. In den 1950er-Jahren war es das einzige Krankenhaus in der weiteren Umgebung, das Schwarze kostenlos behandelte. Dort stellte der Gynäkologe Howard W. Jones eine 2–3 cm große Geschwulst an ihrem Gebärmutterhals (Zervix) fest. Jones entnahm eine Gewebeprobe des Tumors, um ihn pathohistologisch zu untersuchen."), ("p", "Lacks wurde mit internen und externen Bestrahlungen therapiert. Während einer dieser Bestrahlungssitzungen entnahm Jones weitere Gewebeproben aus dem Gebärmutterhals. Diese Proben gab er an George Otto Gey weiter. Gey arbeitete seit Jahren daran, erstmals eine menschliche Zelllinie zu etablieren, die sich dauerhaft im Labor kultivieren ließ. Bisher waren alle Versuche daran gescheitert, dass die Zellen nach wenigen Teilungen abstarben."), ("p", "Gey isolierte einzelne Zellen aus dem Tumorgewebe und brachte sie in Kultur. Schon nach kurzer Zeit fiel auf, dass sich die Tumorzellen völlig anders verhielten, als alle zuvor untersuchten menschlichen Zellen. Sie teilten sich außergewöhnlich schnell und stellten ihr Wachstum nicht ein. Und da war sie, seine potentiell unsterbliche Zelllinie. Klingt nach Science-Fiction? Ist aber Zellbiologie."), ("p", "Während Forscher auf der ganzen Welt bald \"HeLa\" kannten, wusste kaum jemand, dass hinter diesen vier Buchstaben eine Mutter von fünf Kindern steckte. Dass Gey mit diesen Zellen etwas Außergewöhnliches entdeckt hatte, merkte er schnell. Was er damals allerdings noch nicht wusste: HeLa-Zellen würden in den kommenden Jahrzehnten millionenfach vervielfältigt, in Labore auf der ganzen Welt verschickt werden und zu einer der wichtigsten Grundlagen der modernen Medizin werden."), ("h", "Warum waren HeLa-Zellen so besonders?"), ("p", "Jahrzehnte später fanden Wissenschaftler heraus, warum normale menschliche Zellen nicht unbegrenzt wachsen können: Sie unterliegen der sogenannten Hayflick-Grenze."), ("p", "Normale menschliche Zellen sind keine Dauerläufer. Sie können sich nur etwa 40- bis 60-mal teilen. Danach ist Schluss. Dieses natürliche Limit nennt man die Hayflick-Grenze."), ("p", "Der Grund dafür liegt an den sogenannten Telomeren. Man kann sie sich wie die kleinen Plastikkappen an den Enden eines Schnürsenkels vorstellen. Sie schützen die Enden der Chromosomen. Mit jeder Zellteilung werden diese Schutzkappen jedoch ein kleines Stück kürzer. Irgendwann sind sie so weit abgenutzt, dass sich die Zelle nicht mehr sicher teilen kann – sie stellt ihr Wachstum ein oder stirbt ab."), ("p", "HeLa-Zellen spielen nach anderen Regeln. Durch Veränderungen, die unter anderem mit einer Infektion durch Humane Papillomviren (HPV) zusammenhängen, ist in ihnen das Enzym Telomerase dauerhaft aktiv. Es repariert beziehungsweise verlängert die Telomere immer wieder. Dadurch erreichen die Zellen die Hayflick-Grenze praktisch nicht und können sich nahezu unbegrenzt weiter teilen. Heute weiß man, dass Henriettas Tumor durch eine Infektion mit einem besonders aggressiven Typ des Humanen Papillomvirus (HPV-18) verursacht wurde. Das Virus veränderte die Zellen so stark, dass sie ihre normalen Kontrollmechanismen verloren."), ("h", "Was haben HeLa-Zellen in der Forschung bewegt?"), ("p", "Die HeLa-Zellen waren ein Durchbruch in der Forschung.

Genau dafür eigneten sich HeLa-Zellen perfekt. Kurz darauf wurden sie in großen Mengen gezüchtet und in Labore auf der ganzen Welt verschickt."), ("p", "Von da an waren sie praktisch überall dabei. Sie halfen Forschenden, Krebs besser zu verstehen, Virusinfektionen wie HIV zu untersuchen, Gene zu kartieren und neue Medikamente zu entwickeln. Sogar die Auswirkungen der Schwerelosigkeit auf menschliche Zellen wurden mit HeLa-Zellen untersucht. HeLa-Zellen fanden sogar außerhalb der klassischen Medizin Anwendung. Hersteller nutzten sie beispielsweise, um die Verträglichkeit von Pflastern, Klebstoffen oder Kosmetika zu testen. Die Aufklärung der Funktion der Polymerase-Enzyme gelang auch an HeLa-Zellen. Klingt also nach einer universellen Lösung für alles? Fast zu gut, um wahr zu sein. Und tatsächlich zeigte sich einige Jahre später, dass genau diese außergewöhnlichen Eigenschaften ein neues Problem schufen."), ("h", "Die dunkle Seite der HeLa Zellen"), ("p", "Je erfolgreicher HeLa-Zellen wurden, desto häufiger tauchten sie plötzlich dort auf, wo sie gar nicht sein sollten."), ("p", "Eine einzige HeLa-Zelle genügt, um eine andere Zellkultur nach und nach vollständig zu überwachsen. Viele Forschende bemerkten die Verunreinigung zunächst nicht. Jahre später stellte sich heraus, dass zahlreiche vermeintlich unterschiedliche Zelllinien in Wirklichkeit längst aus HeLa-Zellen bestanden. Dieses Problem ging als \"HeLa-Bombe\" in die Wissenschaftsgeschichte ein. Denn im Nachhinein konnte nicht mehr festgestellt werden, ob Experimente, die an humanen Zellen spezifischer Organe durchgeführt werden sollten, nicht doch an HeLa Zellen durchgeführt worden waren. Zahlreiche der an Zellkulturlinien erarbeiteten wissenschaftlichen Erkenntnisse wurden in Frage gestellt."), ("p", "Und auch die Nachkommen Henriettas waren bei der weltweiten Party zum wissenschaftlichen Erfolg nicht eingeladen. Damals wurde diese Gewebeprobe von Henrietta ohne Einwilligung entnommen. Sie wusste nicht einmal, dass mit ihren Zellen geforscht wurde.

Die Familie glaubte zunächst, man wolle sie auf Krebs untersuchen. Tatsächlich interessierten sich die Forschenden vor allem für ihre DNA. Mit ihrer Hilfe sollte eine genetische Karte der HeLa-Zellen erstellt werden, um so Marker zu finden, mit denen HeLa-Zellen eindeutig identifiziert werden konnten."), ("p", "Am Ende ist die Geschichte der HeLa-Zellen viel mehr als die Geschichte einer außergewöhnlichen Zelllinie."), ("p", "Sie erzählt von wissenschaftlicher Neugier, medizinischem Fortschritt und Entdeckungen, die Millionen Menschen das Leben verbessert haben. Gleichzeitig erinnert sie daran, dass Forschung nie losgelöst von den Menschen stattfinden darf, die sie überhaupt erst möglich machen."), ("p", "Vielleicht ist genau das die wichtigste Erkenntnis: Wissenschaft lebt davon, Gewissheiten immer wieder zu hinterfragen – manchmal sogar die eigenen."), ("p", "Und falls ihr nach dieser Geschichte Lust bekommen habt, noch tiefer einzutauchen, kann ich euch Rebecca Skloots Buch Die unsterblichen Zellen der Henrietta Lacks empfehlen.
