Cost-effective storage solution for delivering umbilical cord with efficient isolation of mesenchymal stem cells

Mesenchymal stem cells (MSCs) represent a promising therapeutic candidate for treating many diseases. However, their proliferation and therapeutic abilities decline during the aging process and disease development. Therefore, fetal MSCs derived from the umbilical cord (UC) attract more attention. Storing and delivering the UC is one critical step for efficient MSC isolation. Although the culture medium-based solution is suitable for UC storage, it is not feasible for large-scale preparation because of its high price. Thus, we demonstrate here that a simple solution containing a pH buffering reagent, calcium, magnesium and glucose could be used as a cost-effective storage solution for UC delivery and efficient MSC isolation.
