The career choices of cells
How does an embryonic stem cell decide if it becomes a heart cell or a kidney cell? That’s the question computational biologist Maria Mircea studied for her PhD research. She looked at the inside of individual cells to analyse how they change. This is what she discovered.

A tail with a twist: how the tokay gecko grows a completely new body part
When the tokay gecko loses its tail, a new one grows from resident stem cells at the stump. Each tissue type - muscle, bone, blood vessels and skin - develops from specific stem cells. This discovery by Luthfi Nurhidayat holds potential implications for advancing regenerative medicine in humans. Nurhidayat…

Physics in the picture: cancer cells as an explosion of fireworks
When you think of physics, do you think only of complicated formulas? You’re not the only one. Therefore, every year, the Leiden Insitute of Physics organises the LION Image Award to show another side of physics: beautiful images about intriguing science. The winner of the 2022 photo competition captured…

Bacteria without cell wall gobble up DNA from environment
A bacterium hiding from the immune system and picking up bits of DNA from its environment. The result: gaining new traits, such as better protection against antibiotics. Fortunately, we have not found such a damning scenario yet. However, PhD student Renée Kapteijn did find the first clues, which…

How cells talk by pulling on a fibre network
Mechanics play a larger role in blood vessel formation, and other developmental biology, than previously thought. Cells appear to respond to mechanical signals, such as pressure. Through the extracellular matrix, a network of fibrous proteins, cells can supposedly exchange those mechanical signals over…

Stiffness and viscosity of cells differ in cancer and other diseases
During illness, the stiffness or viscosity of cells can change. Tom Evers demonstrated this by measuring such properties of human immune cells for the first time. ‘The stiffness of certain cells could be a way to make a diagnosis,’ Evers said. He defended his thesis on March 26th.

A unique defence: Bacteria lose cell wall in the presence of virus
Bacteria temporarily live without their cell wall if dangerous viruses are near. A remarkable feature, as the cell wall is a sturdy barrier against threats. Still, the discovery has a logical explanation ánd might be of a consequence for fighting pathogenic bacteria, according to Véronique Ongenae,…

Women’s Day for Biology students
‘It was not always accepted, but I just wanted to be a researcher. Now, I am as happy as can be.’ It is one of the quotes from the International Women’s Day presentation for Biology students. Seven women, working as researchers and teachers at the CML, IBL, and Naturalis, shared their experiences with…

Young, sleeping memory cells are crucial in fighting a reinfection
Researchers from the Netherlands Cancer Institute, the Leiden University Medical Center (LUMC) and Oncode have created a tracking system that can reveal how often cells have divided. This allowed them to find a yet undiscovered population of immune cells: young memory cells that behave like stem cells.…
