The researchers concluded that correspondingly low temperature conditions can prevent hypoxic islet cell damage and that low levels of HMGB1 released from islets might reduce inflammatory responses after transplantation.
"Maintaining low temperature conditions during islet isolation should improve the efficacy of islet isolation in a clinical setting," said the researchers.

Altered oxygen metabolism associated with iPS cells derived from schizophrenic patient
Researchers found that neural cells derived from induced pluripotent stem cells (iPSCs) generated from skin fibroblasts of a schizophrenic patient demonstrated a twofold increase in extra-mitochondrial oxygen consumption as well as elevated levels of reactive oxygen species (ROS). Their work could contribute to a better understanding of schizophrenia's development as a neurodevelopmental disease, they said.
"Brain mitochondria play a key role in neuroenergetics," said study co-author Dr. Stevens K. Rehen of Brazil's National Laboratory for Embryonic Stem Cell Research. "They are essential regula
