Characterization of the double fusion (DF) firefly luciferase (Fluc) and green fluorescent protein (GFP) hP-MSCs. a Schematic representation of the DF reporter gene containing Fluc and GFP driven by an ubiquitin promotion. b, c BLI quantification showed increasing bioluminescence signals with cell numbers (R2 = 0.993). d hP-MSCs are strongly positive for GFP on fluorescence microscopy. e CS-IGF-1C hydrogel is biocompatible in vitro.
