Very small embryonic-like stem cells (VSELs) are a rare and intriguing subpopulation of adult stem cells that exhibit molecular signatures reminiscent of embryonic stem cells. Identified in various ...

Haploid embryonic stem cell research explores the utilisation of cells that contain a single set of chromosomes to probe gene function with unprecedented clarity. This unique genomic configuration ...

Between 1998 and 2009, research being conducted using human embryonic stem (hES) cells expanded primarily using private funds because of restrictions on the use of federal funds for such research.

The stem cell-based embryo model and actual human embryos share many characteristics but are distinctly different. However, internationally, not everyone agrees on the definitions and what we should ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Researchers have succeeded in generating high-quality feline embryonic stem cells using sperm and eggs from testes and ovaries discarded during sterilization surgery. As different as they may seem, ...

Megan Molteni reports on discoveries from the frontiers of genomic medicine, neuroscience, and reproductive tech. She joined STAT in 2021 after covering health and science at WIRED. You can reach ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...
