What You Learned About Cell Division Is Probably Wrong

If you adopt high school biology, you have probably learned about the Cell Department: an important process in all life is officially known as mitosis. For more than a hundred years, students have learned that during mitosis, a parent’s cell becomes round before the two daughters of the same size and size are divided into cells. A new study, however, can re -write many biology textbooks.

Researchers have revealed that mitosis is not always featured in cell round (when a parent’s cell becomes round), which means that as a result, the girls cells are not always symmetrical, or they carry the same function. Detail in one of their jobs Study Published on Thursday in the Journal of Science, and the Cell Department has an important impact on diseases like cancer.

“Students have learned that when a cell is divided, it will create a uniform circular shape. Our study shows that it is not so easy in real living organisms,” Shane Harbert, co-leader of the study, said Shane Herbert, a university, at a university, a university, a university. StatementThe

In the new study, researchers observed the arterial structure in the zebrafish embryos. The growth of new ships consists of slow-moving cells led by a single fast-moving cell. When the lead cell is mitosis, it does not have rounded or experienced. The incomplete section allows it to form two separate cells: a slow dynamic cell and a fast-moving cell take the lead in place of parent cells. Previously, scientists were originally associated with the incomplete cell department with special cells called stem cells.

“Using transparent 1 day old zebrafish fetus allows us to study a dynamic process like cell division inside living organisms,” Manchester University’s Cardiovascular Sciences, co-leader and Holi Lovegrovo said. “So we have been able to make movies of this basic cell behavior and do this reveal the exciting new aspects of how tissues grow”

Furthermore, researchers have noted whether the parent’s cell size can determine whether its section will be symmetrical or incomplete. For example, they observed that short and larger cells are more likely to become round and two similar girls were more likely to be divided into cells. In contrast, long and thin cells have not “round” and as a result, the incompletely divided.

To further investigate it, Herbert, Lovegrov and their colleagues manipulated the size of human parents’ cells through micropatoring. “Micropatoring allows us to produce microscopic patches of certain sizes of proteins, which cells may be stuck,” The first author of the study of the University of Biological Science University, and a post-dictoral research associate Georgia Hulames explained. “The cells will then take the size of the patch this is that this is therefore to change the size of our cells and to check how these sizes will affect the next cell section.”

Herbert said, “Before our research is divided, the cell size can fundamentally indicate that any cell is round and importantly, if its daughters are symmetrical or uneven in size and function,” said Herbert.

As a result, scientists can one day control the size of their parent’s cells and be able to create cells with different functions. More extensively, their analyzes suggest that incomplete sections play an important role in creating different tissues and organ. Studies also have an important impact on diseases like cancer, where incomplete divisions can carry out the behavior of potential cells with the progress of cancer.

In the meantime, our thoughts are with all the students, parents and school administrators who have to spend extra money on the updated textbook soon.
