Librarians of lifeforms

Rather than experiment on a living patient, scientists studying the human body often work with cells that are grown artificially in flasks.

The Cell Services team have the biomedical equivalent of green fingers, nurturing billions of cells to keep each one uncontaminated and thriving.

They’ve filed away thousands of samples of cell types, storing them in vats of super-cold liquid nitrogen so they can be grown again one day. 

At any one time, the Cell Services team hold 6,000 cell lines in the Crick’s deep freeze tanks, ready for scientists to use.

Cell Services technicians use liquid nitrogen to put samples of cells into a state of hibernation. This vessel slowly chills cells in resilient tubes called cryovials, so that they survive the process and can be brought back to life when they’re needed.


Meet Thomas

Thomas Martinez was an experienced research technician when he joined the team but depended on his colleagues to teach him Cell Services protocols.

  • Quote Thomas

    Good technique is not enough. We need to really understand the processes of growing and studying cells. Attention to detail and thoroughness are crucial skills.


    Meet Fatemeh

    Working as a Laboratory Research Apprentice, Fatemeh’s role includes cell culturing and learning the correct laboratory equipment. Cell Services is also in charge of the cryogenic store, retrieving cells from liquid nitrogen for the Crick’s researchers. Before joining Cell Services Fatemeh worked alongside Flow Cytometry, learning how cells are used in various experiments from different labs.

  • Quote Fatemeh

    I enjoy everything in Cell Services as we have to multitask and work under pressure to provide accurate data and results. Because the quality of cells that Cell Services provides to scientists can have far reaching effects and impacts on experiments, it is an essential foundation of the Crick’s research.
