Summary

Story summary

Researchers at the University of Cambridge have developed lab-grown cell clusters called hematoids that can produce human blood stem cells.
Hematoids mimic umbilical cord stem cells and differentiate into red and white blood cells.
They develop beating heart cells and generate blood within two weeks.
The method is more efficient than prior techniques requiring constant supplementation and, in Cell Reports, signals potential drug screening, blood disorder modeling, and regenerative therapies.
