You are not wrong, this mouse is not long ago, the joint development of 3D printing ovarian Northwestern University Mccormick College of Applied Science and engineering and Feinberg School of medicine was born.
The first step: the mouse ovaries removed, isolated follicles and those that can produce hormone cells.
The second step: the basic structure of the new material to print out the ovarian 3D, and isolated follicles and the cell into the "new house".
The third step: to print out the ovary transplanted back into mice, these artificial ovary in mice ", to connect to the body pitch camp", but also in the new eggs in the ovaries gradually mature.
Finally, 7 mice in 3 with new ovarian eggs row of normal pregnancy, gave birth to a healthy baby. In order to make a distinction, before these young eggs had gene editing, will send the green fluorescence.
The future, this technique can help some to restore fertility in women. For example, some young women suffering from cancer, in the chemotherapy and radiotherapy before their ovaries removed some tissue preserved, such as cancer cure, put a new print back. Ovary
This black technology is a new medicine -- "regenerative medicine" (regenerative medicine), the use of alternative organ transplantation, biological engineering, create organ structure and function, and restore health. "Regenerative medicine" from the name to the research target, are full of strong sense of science fiction. At present, researchers have made use of ears. 3D printing technology of trachea, spinal cord, endometrium, are now trying to print the heart or liver.
The ovarian structure 3D to print out: a gelatin layer of 15 mm x 15 mm
"The field of regenerative medicine", some of the China projects are at the forefront of the world.
Study on genetic and developmental biology, Institute of Academy of Sciences China regenerative medicine research center director Dai Jianwu team, engaged in the research of regenerative medicine for more than 10 years. From 2013 onwards, they and the Nanjing Gulou Hospital cooperation, using stem cells composite scaffold, scar repair of the endometrium. The latest data, there have been 13 women gave birth 14 healthy babies, and 6 fetuses is pregnant.
Maybe one day, the human baby will by 3D printing the womb.
However, you think this is all? Let's put up a brain hole. The future, 3D printing can print all human organs? These organs can be assembled into a complete person?
