Cornell researchers have uncovered the genetic triggers that cause male and female bovine embryos to develop differently, as early as seven to eight days after fertilization. The breakthrough in basic ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

In a quiet lab at Cornell University, scientists have made a discovery that could reshape how we think about life’s earliest stages. Researchers found that male and female embryos begin developing ...

Researchers at Newcastle University in England report they have coaxed the first human sperm cells from embryonic stem cells, in a remarkable demonstration of how quickly the field of stem-cell ...

New research has mapped the cell types that specialize to form reproductive organs in both sexes, identifying key genes and signals that drive this process. The findings offer important insights into ...

A viral defense mechanism can be used to accelerate the creation of female stem cell lines in mice. The findings can boost efforts in medical research, drug testing, and regenerative therapies, ...

The International Society for Stem Cell Research (ISSCR) today announced the 10 most downloaded papers of 2025 from Stem Cell ...

These genes helped fuel faster cell division and quicker development. In contrast, female embryos activated genes tied to preparing for reproductive development and building immune system components.

ITHACA, N.Y. -- Cornell researchers have uncovered the genetic triggers that cause male and female bovine embryos to develop differently, as early as seven to eight days after fertilization. The ...
