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 ...

Hematopoietic stem cells (HSCs) are the cornerstone of lifelong blood formation, arising during embryogenesis from specialised endothelial precursors in a process known as the ...

A study in mice has found that maternal gut microbiome composition during pregnancy has long-term effects on offspring stem cell growth and development. The researchers, headed by Parag Kundu, PhD, at ...

When stem cells are injected into thick tissues, they often clump together and die from lack of oxygen or nutrients, making ...

Stem cells work throughout our lives as a sort of handyman, repairing damaged tissues and renewing some normal ones, like the skin we shed. Scientists have come to understand much about how stem cells ...

Cells contain a blueprint in the form of DNA that dictates what they can make. This blueprint is converted into a message (mRNA), which is then converted into a protein. Although DNA remains the same ...

Microscopy image of a PGA at day 8 showing the early tissues supporting the embryo, including the amniotic sac and the yolk sac-like structures, surrounded by (extra-embryonic) mesoderm tissue.

Researchers have created a way to guide and control the development of stem cells into specific tissues and organs, opening the door to developing a means of one day tackling complex diseases like ...
