What You Learned About Cell Division Is Probably Wrong

If you receive high school biology, you probably obtained information about the cell department: it is officially called mitosis in all forms of life. For more than a hundred years, students become spherical in the parent cell before dividing the same size and the form of the form in the mitosis. A new study, but can rewrite many biology textbooks.

Researchers always turn on the cells (when parent cell spherical), the resulting girl cells are not always symmetrical and did not carry the same function. Their job is detailed in a learn It was published in the magazine on Thursday and conducts important influences to understand the cell section in diseases such as cancer.

“When the students are divided into a cell, it will create a single spherical form. statement.

In the new study, researchers observed the formation of blood vessels in zebrain embryos. The growth of new ships consists of slow moving cells, led by a fast-moving cell. When the lead cell mitosis lives, he did not experience spherical or experience. Asymmetric section, allowed two different cells: a cell moving cell and a fast-moving cell, a cell that moves a fast moving in place of parental cell. Previously, scientists were mainly associated with the Asymmetrical Cell Branch with specialized cells called stem cells.

“Transparent 1-day zebrafish embryos allows you to learn a dynamic process as a cell section in a living organism,” said Holly Lovegrove, the author of the research and the teacher of cardiovascular sciences at Manchester University. “Therefore, we will make the films of this fundamental cell behavior and discover the interesting new aspects of how tissues grow.”

In addition, researchers said that the division of the form of a parent cell could determine whether it is symmetrical or asymmetric. For example, they observed that shorter and wider cells are spherical and divided into two similar girls. On the contrary, the longer and delicate cells were not “rounded” and as a result of asymmetrically divided.

To explore this, Herbert, Lovegrove and colleagues to manage the size of human parental cells through micropatertning. “Micropatertning allows cells to create special shape microscopic patches of proteins where cells can be pasted,” he said, the First Author of the Research and the University of the School of Manchester Biological Sciences. “The cells will then take a picture of the patch. Therefore, it allows you to change the shape of cells and how these forms affect the subsequent cell division.”

“Our research shows that the image of the cell can be found in the form of the cell before the division, or that it can be directly directly or as symmetrical or asymmetric,” Herbert said.

As a result, scientists can create cells with different functions by managing the form of parental cells one day. They show that their analysis plays an important role in creating different tissues and bodies of asymmetric units. The research has an important impact on diseases such as cancer, there can lead to different cell behavior related to an asymmetric section, related to cancer.

Meanwhile, all our thoughts may have to spend all the students, parents and school administrators, to spend excessive tutorials soon.
