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

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 ...

Stanford Medicine pediatric hematologist Agnieszka Czechowicz, MD, Ph.D., has devoted her research career to improving ...

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 ...

Understanding how these cells develop and function is like decoding a complex puzzle. “By perfecting stem cell methods that mimic the development of the normal blood stem cells found in our bodies we ...

How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the ...

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.

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 ...

A chronological map of the fetal brain reveals when key cells emerge and provides clues about autism and cancer.
