21 August 2024 Three images of the cell at different stages of mitosis. In the left: round navy shape and irregular thick magenta line within it. In the middle: the same round shape with two irregular magenta shapes. On the right: Two round navy shapes connected with each other. Each of them holds shiny magenta-yellow clusters.

The forces behind chromosome repulsion and attraction during cell division

Science & Technology EMBL Heidelberg researchers discovered how a protein switches between repelling and gluing chromosomes during cell division. This helps the mother cell to divide the genome equally into two daughter cells and cluster chromosomes inside the daughter nuclei, ensuring a successful cell division.

ERC Consolidator Grants awarded to two EMBL researchers

EMBL AnnouncementsLab Matters Alba Diz-Muñoz and Arnaud Krebs from EMBL Heidelberg have received grants to work on projects that aim, respectively, to understand the cellular mechanics that control cell division and investigate the regulatory networks that govern transcription factor function.

Cell duplication

Science & Technology What looks like a pair of scary alien eyes is actually the final stage in the duplication of a cell. Cell duplication is preceded by a process called mitosis, in which the replicated chromosomes are separated into two new nuclei. Mitosis is the prerequisite for a cell to divide into two identical…

Stop and go

Science & Technology A traffic policeman standing at a busy intersection directing the flow of vehicles may be a rare sight these days, but a similar scene appears to still frequently play out in our cells. A protein called Lem4 directs a crucial step of cell division by preventing the progress of one molecule while…

1 April 2010 Each of these large images of dividing cells is composed of several microscopy images of human cells in which different individual genes were silenced. The smaller images are placed according to genes’ effects: images for genes that affect chromosomes make up the chromosomes (red/pink), while the mitotic spindle (green) is composed of images for genes that affect it.

Movies for the human genome

Science & Technology Name a human gene, and you’ll find a movie online showing you what happens to cells when it is switched off. This is the resource that researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and their collaborators in the Mitocheck consortium are making freely…

Researchers shed light on shrinking of chromosomes

Science & Technology A human cell contains an enormous 1.8 metres of DNA partitioned into 46 chromosomes. These have to be copied and distributed equally into two daughter cells at every division. Condensation, the shortening of chromosomes, allows the cell to handle such huge amounts of genetic material during cell…
