Abstract:

BACKGROUND: General assessment of viability of umbilical cord mesenchymal stem cells during transport is not considered at home and abroad.   
OBJECTIVE: To explore the effects of different transportation conditions such as albumin and transport time on survival rate of umbilical cord mesenchymal stem cells. 
METHODS: Umbilical cord mesenchymal stem cells cultured in vitro were divided into experimental and control groups. Each of group contained 3.15×109/L cells in 3 mL normal saline. The experimental group contained 1% albumin in dark environment. The control group included two subgroups: dark preservation group with the absence of albumin and light preservation group with the presence of albumin. Cell counting, trypan blue staining and cell survival rate were compared at 0, 2, 4, 8, and 24 hours. 
RESULTS AND CONCLUSION: Compared with the control group, no cell loss was observed in experimental group (with the presence of albumin in the dark) and a 90% viability ratio was achieved at 8 hours. In the control group without albumin, loss rate reached 38.5% and survival rate reached 86% at 8 hours. Results revealed that 1% albumin predominantly improved cell survival rate in long-distance transport of umbilical cord mesenchymal stem cells. When transport time was more than 8 hours, cell loss rate increased and cell survival rate downregulated. Our experimental data demonstrated that umbilical cord mesenchymal stem cells preserved in normal saline consisting of 1% albumin placing in dark environment at 16 ℃ apply to clinical application criterion in 8 hours.
