According to reports, an Israeli research team has succeeded in cultivating a pair of artificial organs, also known as "organoids", from the cells of some mice.
This microscopic biological organ is manufactured with the aim of gaining insight into the development and function of male infertility, addressing male infertility and advancing male infertility.
According to statistics, the number of couples fighting infertility is increasing year by year. According to official data from the Ministry of Health, Labor and Welfare, 41 in 4 couples are undergoing infertility**. However, the specific causes of male infertility are not well understood.
Professor Nitzangonen from Bar-Ilan University in Israel said at a press conference: "These artificial products are very promising and can provide a basis for developmental and functional research, and it is expected that they will be applied to sexual development disorders and male infertility in the future." ”
Artificial "sperm organs" are microscopic artificial organs made by cell culture, and their tubular structure resembles a real **.
An artificial organ is a miniature organ that functions like a human organ and can be cultured from cells in the laboratory to study organ development and disease.
The study was published in the International Journal of Biological Sciences (January 12, 2024). The researchers removed juvenile ** cells from newborn mice and cultured them.
Jingqi is one of the male *** officials, also called **, mainly producing male germ cell sperm and male hormone testosterone.
The culture cycle of mouse ** cells is 9 weeks. Theoretically, this is enough to complete the sperm production and hormone secretion process.
While we don't know if this artificial sperm organ is actually capable of producing sperm, the researchers have observed signs of incipient sperm cell production.
The success of this study was made possible by the fact that the researchers succeeded in creating an environment in which the maturation of the sperm organs and the growth of the seminiferous ducts were possible.
In fact, most miniature organs are made according to the early stages of the organ, so this kind of mature artificial** is very rare.
In the future, we plan to use human cells to create sperm-like bodies.
It is worth mentioning that the "artificial sperm organ" created this time was actually cultured from just a group of mouse cells.
While this microbial organ is very promising as a model for studying organ development, Professor Nitzangonen believes that similar artificial** will be created from human cells in the future.
According to Professor Goning, one in three adolescent boys who have undergone chemistry** or radiation*** will be infertile.
If we consider that 85% of children with cancer will become adults, their reproductive ability will be greatly affected, but the current method of repairing children's reproductive function is not very successful, therefore, this research successfully made "artificial sperm organs", and it is also expected to make similar artificial organs from the cells of prepubertal boys in the future, adding new hope for future medical research and **.
