Professor Rob Cross, Professor of Mechanochemical Cell Biology at Warwick Medical School, said: «Every cell in our bodies contains a railway network, a system of tiny tracks called microtubules that run between important destinations inside the cell and allow cargo to be carried from one place to another.

Every cell in our bodies contains a railway network, a system of tiny tracks called microtubules that run between important destinations inside the cell and allow cargo to be carried from one place to another, reports Professor Rob Cross, Professor of Mechanochemical Cell Biology at Warwick Medical School.

If you imagine the female egg cell (and later, the fertilized egg) as a spherical planet with its own intrinsic biological geography, then certain characteristics of that cell — the location of protein molecules or RNA messages or biochemical traits like pH or even the internal connective structures called microtubules — will be more prominent in certain regions, like one hemisphere as opposed to the other, or near the surface rather than near the core.

Normally, tau proteins help to stabilize the hollow tubes called microtubules that help give cells their shape.

Using this biologically accurate model of how dynein moves the microtubules within the axoneme, Ingber and Reilly created a short film called «The Beginning,» which draws parallels between sperm swimming toward an egg and spaceships flying toward a planet in space, giving an artistic bent to a scientific topic.

The axoneme's movement is accomplished via rows of motor proteins called dyneins that are attached along the microtubules and exert force on them so the microtubules «slide» past each other, which then causes the entire axoneme and sperm tail to bend and move.

The protein assembly line consists of microtubules that serve as train tracks on which the raw materials — including messenger RNA (mRNA)-- are carried to the protein - making machinery, called ribosomes.
