Egg cells do not pass their waste in the same way as other cells

Human eggs seemed to withdraw their garbage more slowly than other cells, which helps them to avoid wearing and tightening – and explain why they lived longer.
Every woman was born with the last number of egg cells, or oocytes, which should live for about five decades. For cells, that is an unusual time. Although some human cells, like brains and eyes, can live as much as you do, most have more processes that allow them to cause them to reduce them in the long run.
It should recycle cells in their proteins as a form of needed home care – but it will come at a cost. The energy consumed in this process can generate molecules called reactive species of oxygen, or ros, which causes random injury to the cell. “This is the damage that occur in the background all the time,” as Elvan Böke to the center for Genomic Regulations in Spain. “The more ros have, more damage with.”
But healthy eggs seem to prevent this issue. To find out why, the böke and his companions study the harvested eggs at the bottom of a microscope. Cells are placed in a liquid with fluorescent dyes, binding cellular components, called lysosome, acting as “plants recycling”, as Gabriele Zaffagnini At the University of Cologne in Germany.
The bright dye revealing waste of rubbish in human eggs is less active than the same components of other cells in small mammals, such as mice. Zaffagnini and his colleagues say it can be a form of self preservation.
Leaving their garbage disposal mechanism can be one of the many ways in the egg egg cells achieve their long lives, as Zaffagnini. Böke thinks to avoid injury, human oocytes “put a brake at all”. If all cell processes run slowly in egg egg cells, he says, it can result in the lowest levels of harmful ros, and therefore not risky damage.
Because the delay in the process of recycling the protein seems to help the egg cells to keep their health, fail to do what can be explained what are some of the oocytes. “The way I see it is, it can be an explanation why the oocytes of man really turns dysfunctional after an hour,” as Emre Seli at the Yale School of Medicine. “It can be a sign of advanced assessment of all things wrong with the oocytes of man,” he said.

Evaluating egg health in this way can improve fertility treatment. “We know that protein damage is important for cell safety, so 100 percent affect fertility,” says Böke. He pointed to study focused on healthy eggs; He said the job to compare cells with eggs from people affected by complications with fertility continuously. “If there is a high rose in the cell, there are poor results of IVF,” he said.
Egg egg cells are not yet understood, because it is difficult to study. “(They) hard to work with, because the sample limit is an issue,” says Böke. Seli says this obstacle is a “large layer” of the problem, which also includes regulations that restrict the study of egg cells and lack of funds.
If these difficulties can be understood, Zaffagnini says, there may be “odd” results. “It’s so amazing,” he said.
