  • Primary cilium under a transmission electron microscope (TEM)
    Rights: Tony Poole Published 22 July 2021 Size: 180 KB Referencing Hub media

    The primary cilium is a small organelle that acts like an antenna, co-ordinating information about the cell’s surroundings. At just 200 nm wide, the primary cilium is only just big enough to be viewed through an optical microscope, but its structure can be studied in detail by using a transmission electron microscope (TEM).

    Associate Professor Tony Poole uses TEM microscopes to unlock the mystery of how the primary cilium works. Tony’s story is an excellent example of the changing nature of scientific knowledge and how new information can change the way we think about things.
