Summary

Story summary

Researchers aim to grow Rh null blood in laboratories to address its scarcity.
Rh null blood is found in only 50 individuals globally and is compatible with all Rh types.
CRISPR-Cas9 gene editing has been used to replicate this blood type in the lab.
Large-scale production remains challenging as banks of rare blood are established without gene editing, alongside RESTORE and other trials.
