If the chromosomal number is reduced, eukaryotic cell division is classified as open orthomitosis In the mitotic metaphase (see below), typically the chromosomes (each containing 2 sister chromatids that developed during replication in the S phase of interphase) align themselves on the metaphase plate. Then, the sister chromatids split and are distributed between two daughter cells. In meiosis I, the homologous chromosomes are paired before being separated and distributed between two daughter cells. On the other hand, meiosis II ...

Almamater Knownfor Scientific career Fields Robert Remak (26 July 1815 – 29 August 1865) was a Polish embryologist, physiologist, and neurologist, born in According to historian Remak obtained his medical degree from Friedrich Wilhelm University in Berlin in 1838 specializing in neurology. Despite his accomplishments, because he was a His son References [ ] • Magner, Lois N. A history of the life sciences, p185 • Figlio, K.; Weindling, P. (June 1984).

An ascidian consisting of 24 cells. The stiffness of the cells preparing for cell division is measured with a micropipette. Credit: Benoit Godard / IST Austria During cell division, a parent cell divides into two daughter cells. Their new role and function depend on the orientation of the division plane. A crucial factor guiding this division orientation is the shape of the mother cell. Now, Professor Carl-Philipp Heisenberg and Benoit Godard, a postdoc in the Heisenberg lab, discovered that the dividing cell softens and thus becomes deformable by mechanical tension originating from neighboring cells, thereby explaining how tissue tension influences cell division orientation. "The neighboring A new model organism Investigating cellular interactions within a tissue is challenging. Due to the large number of cells involved, cause and effect are hard to disentangle. Therefore, Carl-Philipp Heisenberg utilized a unique model organism. Ascidians, small marine invertebrates, develop nearly identical to vertebrates but only consist of very few cells. Additionally, the cell's fate is set quite early. With fewer cells and a predetermined development, ascidians allow scientists to investigate the tissue dynamics more precisely. Observing dynamics cell shaping It is known for more than a century that cells tend to divide perpendicular to their long axis. Previously, cells undergoing division were thought to be stiff and thus insensitive to mechanical forces from their environment aff...
