Placentas require specialized freezing technologies, including antifreeze and liquid nitrogen, for long-term preservation.

“So, you have to develop technologies, and that's what we have done, to put antifreeze in that placenta such that you can then put them into liquid nitrogen. So, in other words, it's not what you have in your kitchen. I mean, this is minus 100, 200 degrees centigrade, so very, very cold.”

“if you put antifreeze in it, you could put the whole placenta in the freezer. Or what you could do, that's another that we have developed, we can pull cells out and make a second bag, and put the bag into the freezer.”
