Step toward 'ink' development for 3-D printing a bioprosthetic ovary

For the first time, scientists identified and mapped the location of structural proteins in a pig ovary. Ongoing development of an 'ink' with these proteins will be used for 3-D printing an artificial (or bio-prosthetic) ovary that could be implanted and allow a woman to have a child.

Combining neurologic and blood pressure drugs reduces breast tumor development in mice

Adding a medication used to treat epilepsy, bipolar disorder and migraines to a blood pressure medicine reversed some aspects of breast cancer in the offspring of mice at high risk of the disease because of the high fat diet fed to their mothers during pregnancy. Conversely, this treatment combination increased breast cancer development in the offspring whose mothers had not been fed a high fat diet during pregnancy.
