Cord clamping method may boost stem cells in preemies
NCT ID NCT07385326
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether the way doctors clamp the umbilical cord affects stem cell levels in preterm infants. 49 babies born between 28 and 36 weeks were randomly assigned to immediate clamping, delayed clamping, or cord milking. Researchers measured stem cell counts in blood samples after birth to see if any method led to higher levels.
