Figure 4From: Effect of different freezing rates during cryopreservation of rat mesenchymal stem cells using combinations of hydroxyethyl starch and dimethylsulfoxideEffect of HES with different molecular weight distributions on MSCs cryopreservation. Viability of MSCs after cryopreservation with 10% HES of different molecular weight distributions (109–609) in combination with DMEM or FCS, measured 3 days after thawing (A) and by methylene blue staining after osteogenic differentiation for 14 days (B). Alkaline phosphatase activity of cryopreserved MSCs after osteogenic differentiation for 14 days (C).Back to article page
