The University of Hawaii has created the first of its kind: A Frozen Coral Cell Bank. While these frozen cell banks already exist for seeds and plants in order to preserve them in the extremely unfortunate case that they would be needed – the University of Hawaii developed their frozen coral cell bank in order to preserve the biodiversity of the Hawaiian coral species.
Here’s how it works: Because frozen blanked cells are viable, the frozen material can be thawed in 1 to 50 or – in theory – even up to 1,000 plus years. Some of these cells have already been thawed out in the form of frozen coral sperm cells. They were successful in fertilizing coral eggs to produce developing coral larve according to a biologist named Mary Hagedron who works at the University.
So far, the Hawaiian coral cell bank has frozen sperm and embryotic cells from mushroom coral and rice coral.
