A Kyoto University study suggests modern blood and immune cells arose about 700 million years ago alongside the first multicellular animals, showing that macrophage-like cells and key immune pathways trace to unicellular ancestors; the gene FOS and other developmental pathways appear inherited from those ancient microbes, offering a shared biological legacy across vertebrates and potential insights into disease origins.
Researchers mapped the evolution of blood cells across animals, revealing a 700‑million‑year link between modern blood cells and unicellular ancestors. Macrophages show the strongest similarity to these early cells, and the FOS gene traces back to a unicellular origin, suggesting first blood cells arose as multicellular life emerged. Over time, mast cells, T cells, red blood cells, and B cells branched from these roots. The new method reconstructs a 700‑million‑year blood‑cell family tree and could help study disease origins, including cancer.
Researchers at the University of Cambridge have developed a lab-created embryo-like structure called 'hematoids' that can produce human blood cells, mimicking early embryonic blood development, with potential applications in understanding blood disorders and regenerative therapies.
Scientists have created embryo-like structures from stem cells in the lab that can produce human blood cells, opening new avenues for regenerative medicine and understanding early human development, with potential applications in treating blood disorders and customizing therapies using a patient's own cells.
Researchers from the Wellcome Sanger Institute have discovered that the seemingly useless yolk sac in human embryos actually plays a crucial role in the development of the immune system. By sequencing RNA strands from human yolk sac cells, the researchers created a detailed atlas of the tissues, revealing that the yolk sac is responsible for producing the first blood cells and contributing to various important early functions. The study also identified significant differences between human yolk sac tissues and those in typical lab models, providing valuable insights into early human development and potential applications in disease research and tissue engineering.
