Method of cryopreserving stem cells |
摘要 |
A non-linear cooling cryopreservation method for improving cryopreservation protocols for cells that involves producing a simulation of cellular responses to a range of cooling parameters; determining optimal cooling parameters required to minimize cryoinjury to the cells using simulation of cellular responses and experimental results; and incorporating optimal parameters into the protocol. The simulation is based on mathematical models of cellular parameters. A non-linear cooling cryopreservation protocol for cryopreserving stem cells is also disclosed that does not require cryoprotectants. |

1. A method for cryopreserving stem cells, the method comprising:
providing isolated stem cells in a serum-free liquid culture medium; a. Cooling the stem cells to a first temperature between −5° C. and −15° C. and holding them for a first period of time between 1 and 30 minutes at said first temperature to generate ice outside of the stem cells; and thereafter b. Cooling the stem cells to a second temperature below −60° C. for storing the cells; wherein steps a and b are carried out in the absence of a permeating cryopreservant. |
