Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...

Formation of the energy-producing machinery in the proximal tubule of the nephron is an essential step in differentiation. The authors show that mitochondrial localization depends on LRRK2, the ...

Then researchers placed blastoids and embryos donated after infertility treatments inside the little device and watched it ...

Researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells. University of Pittsburgh ...

The team placed blastocysts—embryos 5-6 days after fertilization that were donated following IVF procedures—onto the ...

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation, or hematopoiesis—a first for the field. In an article ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

Implantation, one of the most poorly understood phases of early human development, occurs in the depths of the womb, at a ...

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 ...
