Chinese scientists have developed a new low-cost technology for cell cryopreservation, which is expected to lead to a breakthrough in cell therapies treating blood diseases and some cancers. Cell therapy refers to transplanting cells into a patient after in vitro culture in order to repair or replace the damaged tissues or cells. The cryopreservation technology, allowing cells to stop metabolism at 80 C or 196 C below zero, could preserve their viability and functions for a longer time. A national patent has been granted for the new technology and the researchers have applied for a Patent Cooperation Treaty patent.
