Serial, frozen sections (40 μm, coronal) were prepared as described above. For immunofluorescence staining of DCX and GFAP, free floating sections were incubated for 3 h in a blocking buffer consisting of 10% normal donkey serum and 0.3% Triton X-100 in PBS and subsequently overnight in 1% BSA, 0.3% Triton X-100 in PBS containing either a goat anti-DCX (Santa Cruz #SC8066; 1:250) or a rabbit anti-GFAP (Sigma #180063; 1:1000), respectively. After rinsing with PBS, the sections were blocked in the aforementioned blocking buffer for 3 h and incubated in the dark for 6 h with either secondary Alexa Fluor-594 donkey anti-goat IgG antibody (Life Technologies; 1:1000) or secondary Alexa Fluor-594 donkey anti-rabbit IgG antibody (Life Technologies; 1:1000). The sections were then rinsed in PBS. After the final PBS rinse, the sections were mounted on SuperfrostPlus slides (Fisher), allowed to dry at RT in the dark, coverslipped and stored at -20°C. The sections were imaged with Olympus IX81/DSU spinning disc confocal microscope.

To analyze the ASC cytokine expression, ASCs were cultured on the coverslips (VWR International) until confluence. The ASCs were then fixed with 4% paraformaldehyde (Alfa Aesar, Ward Hill, MA, USA) in PBS for 1 h, and treated with 0.1% Triton X-100 (Sigma-Aldrich) for 15 min. After blocking with 3% bovine serum albumin (BSA, Sigma-Aldrich) in PBS at room temperature for 1 h, the slides were incubated with rabbit polyclonal anti-vascular endothelial growth factor (VEGF) antibody (1:100 dilution, sc-507; Santa Cruz Biotechnology), goat polyclonal anti-insulin-like growth factor-1 (IGF-1) antibody (1:100 dilution, sc-1422; Santa Cruz Biotechnology), or rabbit polyclonal anti-hepatocyte growth factor (HGF) antibody (1:100 dilution, sc-7949; Santa Cruz Biotechnology) at 4°C overnight. After incubation with secondary antibody Alexa Fluor 594 goat anti-rabbit IgG antibody (1:200 dilution, A11012; Life Technologies) or Alexa Fluor 594 donkey anti-goat IgG antibody (1:200 dilution, A11058; Life Technologies) at room temperature for 1 h, cell nuclei were counterstained with 4¢,6-diamidino-2-phenylindole dihydrochloride (DAPI; Santa Cruz Biotechnology).
The images were taken with a fluorescence microscope (Zesis Axio observer Z1 Inverted microscope; Carl Zesis Canada Ltd., Toronto, ON, Canada).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
