Would it be too disruptive to your study to inject a small amount of
cryomatrix intra-abdominally prior to freezing? I think the internal
organs, being small and fragile, are not sticking to one another
I also suspect there is quite a high fat component in there as well,
so with fat, a colder cutting temperature is generally better.
By the way, I haven't tried the intra-abdominal injection technique
myself. Let me know if you try it and how well it works. Good luck.
