Scientists grow real blood vessels inside tiny lab-made heart, lungs, liver

SMRTR summary

Researchers have made a breakthrough in growing blood vessels within lab-grown organs, addressing a key challenge in organoid development. Two separate teams successfully created mini-organs with integrated vascular networks, mimicking natural organ development more closely. This advancement allows for larger, more functional organoids that can better replicate real organ behavior, potentially revolutionizing disease research and drug testing.
