Mice with 3D-printed ovaries give birth to live young

Here is an interesting development in the world of science: Mice have successfully reproduced after being implanted with bioprosthetic ovaries created with a 3-D printer, according to research published in Nature Communications.

Read a summary of the research in Mice Successfully Reproduce with 3-D Printed Ovaries in TheScientist online.

The research has important implications for cancer patients of child-bearning age whose cancer treatments have left them sterile.

Scientists create male mice with no Y chromosome

By Chloe Mitchell, ASAP/ASAS Intern

February 18, 2016 – A recent article in Science highlights new research from reproductive biologists at the University of Hawaii, Honolulu, who have produced male mice lacking a Y chromosome. Monika Ward and colleagues developed the engineered males from mice with a single X chromosome via genetic manipulation on the X chromosome and another chromosome. This led to the creation of male mice capable of immature sperm production. Read more »


Genomics for phenotype prediction and management purposes

By Samantha Kneeskern

January 11, 2016 – Genomic selection has been implemented worldwide in dairy breeding programs (Please read Genomic selection: A paradigm shift in animal breeding in Taking Stock). Reference populations or large sire calibration groups include bulls with highly reliable breeding values that are genotyped with high-density SNP-chip panels. Read more »
