Figure Lengend Snippet: Cell and extracellular matrix (ECM) composition of mCSs formed in ULA U-well plates and PDL-coated plates. ( a , b ): Images of mCSs stained by endothelial cell (EC) marker (CD31, red), progenitor cell markers (c-Kit, red; Sca-1, red; Oct4, red), smooth-muscle cell marker (SMA, green), mesenchymal markers (CD105, red; CD90, green; CD73, green), and ECM proteins (COL I, green; FN, green). Nuclei were stained with DAPI. Yellow arrows indicate positive staining. ( c ) Bar plot of a positive staining cell fraction per nuclei within the mCS slice, n = 3, * p < 0.05. ( d ) Bar plot of fluorescence intensity signal normalized per mCS slice area, n = 3, ** p < 0.01. SMA—smooth muscle actin, COL I—collagen type I, FN—fibronectin.
Article Snippet: The EDCs were trypsinized, washed in ice-cold FASC buffer (5% FBS, 0.1% sodium azide in Ca 2+ , Mg 2+ -free DPBS), and incubated with primary antibodies to CD105 (#120404, Biolegend, San Diego, CA, USA), Sca-1 conjugated with PE/Cy7 (E-AB-F1191UH, Elabscience, Wuhan, China), CD90 conjugated with FITC (E-AB-F1283UC, Elabscience), CD31 (#553370; BD, San Diego, CA, USA), and CD45 conjugated with PE (E-AB-F1136UD, Elabscience) or with isotype IgGs for 30 min on ice.
