Much of the genome is made up of repetitive DNA sequences that trace back to ancient mobile elements, many of which have lost ...

Researchers in Japan have successfully generated lung cells similar to alveolar epithelial type 2 (AT2) cells from mouse embryonic fibroblasts without using stem cell technology. The AT2-like cells ...

When injected into mice with retinal disease, the special retinal blood cells integrated into the damaged tissue to ...

Northwestern Medicine scientists have discovered that one of the body's most fundamental biological processes—how red blood ...

New research from scientists at the Massachusetts Institute of Technology (MIT) describes a process for converting skin cells directly into neurons that bypasses the induced pluripotent stem cell ...

To create mouse-rat "chimeras," researchers injected rat stem cells into mouse embryos that lacked some genes for brain development. Creative Touch Imaging Ltd. / NurPhoto via Getty Images Scientists ...

What does it feel like to be a rat? We will never know, but some very unusual mice may now have an inkling. In a series of new experiments, bits of rat brain grew inside the brains of mice. Donor stem ...

Messenger RNA can travel between different types of stem cells through tunnel-like structures, as revealed by a new study. By studying interactions between mouse and human stem cells, they discovered ...

The mouse on the left is a chimeric with dark eyes and patches of black fur, a result of stem cells derived from a choanoflagellate Sox gene. The wildtype mouse on the right has red eyes and all white ...
