Biomaterial Applications in Cell-Based Therapy in Experimental Stroke

Representative images of in vivo and ex vivo detection of hyaluronan-acid (HA) hydrogel. (a)Magnetic Resonance Imaging (MRI) weighed in T2, hydrogel detected at different time points (days one, seven, and fourteen after administration). (b) Cresyl violet staining of HA hydrogel acquired two weeks after administration, noted in (×2) (b) and (c) (x10) magnification. These images demonstrate efficient local gel formation instead of liquid diffusion which would be due to a delayed polymerization after infusion and the in vivo stability of HA hydrogel.
