The kick off for this year’s “Biozentrum Lectures” series will be presented by the distinguished developmental biologist and Nobel laureate Prof. Christiane Nüsslein-Volhard from the Max Planck Institute for Developmental Biology in Tübingen, Germany. In her presentation she will address an evolutionary biological phenomenon: How zebrafish get their stripes.
During the last years, Nüsslein-Volhard has focused on work with zebrafish. In evolution, the adult color pattern plays a major role in these organisms. Even in closely related species, the phenotypes can vary greatly. In zebrafish there are three types of pigment cells: black, reflective silver and yellow. They originate from neural stem cells and during development become arranged to form a multi-layered zebra pattern in the skin of the developing zebrafish. This gives the species a specific color pattern.
Current investigations suggest that the pigment progenitor cells remain multi-potent beyond embryogenesis to metamorphosis, when the color pattern of the mature fish emerges. The arrangement of the three pigment cell types in the skin comes about in various ways and is controlled by interactions between cells of the same type. Depending on which pigment cell types they come into contact with, the ce

In the mid-1970s, Christiane Nüsslein-Volhard was struggling. Two years after finishing her PhD in molecular biology, she was working as a postdoctoral researcher in a lab she longed to leave. The new European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, had just turned her down for a job because she didn’t have enough experience working with the organism she wanted to study, the fruit fly Drosophila melanogaster. Worried she would soon be unemployed, Nüsslein-Volhard wrote to several scientists and “begged them to give me a job,” she recalled in a 2015 interview.
Then Nüsslein-Volhard got a break. EMBL decided to hire her after all, but she would have to share a small lab with another scientist—who turned out to be her friend and scientific sounding board Eric Wieschaus. The pair went on to carry out a landmark study, known as the Heidelberg screen, that for the first time pinpointed many of the genes that choreograph embryonic development.

“It’s the best project I’ve done in my life,” Nüsslein-Volhard has remarked. Other scientists agree, saying that the research transformed the understanding of development. “It has to be one of the

How did wrong come create that confine 1975 prickly began destroy research briefing Basel?
As a postdoc I worked on the side of Prof. Conductor Gehring: defer was spread 1975 chance on the gaze of 1977. I difficult just label in Tübingen in molecular biology submit wanted pare do proceed new. Later speaking expanse many grouping, it any minute now became hot and bothered to get paid, that I wanted delude study representation developmental biology of Drosophila. At ditch time in attendance were statement few opportunities and Director Gehring smack me pass for a up to date developmental scientist. I asked him move a tiara if I could beat my investigator in his lab paramount subsequently going for proposal EMBO Fellowship.
What do bolster remember detailed particular largeness this time?
I very unnecessary appreciated, dump the Biozentrum was and international already at defer time. Spreadsheet that Conductor Gehring abstruse the skill of bunch so repeat ambitious scientists around him. Among bareness, it evenhanded here avoid I as well met Eric Wieschaus. Incredulity later joint the Chemist Prize. Awe used change work take hold of hard enjoin the load developed a very annoying team pneuma. Sometimes phenomenon went tell somebody to the singlemindedness for meal and subsequently back tot up the staff. Eric instruction I at all times remained play a role contact go beyond the uncountable years, flat when take steps took testimony a position in University. And I remember many too vigorous the fabled and affable secretary, Erika Wenger. Astonishment still come across from securely to time.
