Sections were first fixed in 4% paraformaldehyde for 15 min. After that they were treated with 0.1% Triton X-100 for 1h and afterwards blocked by goat serum for 1h at room temperature. Specimens were incubated with primary antibodie of Cx43 (Santa Cruz, sc13558, lot# k2408, 1: 100) diluted with PBS for 3h at 37°C. After washing 3 times with PBS, specimens were incubated with secondary antibody 1:500 Alexa Fluor 594 conjugated anti-mouse (Invitrogen) for 1h at room temperature. Finally all sections were covered with cover slip and observed under confocal microscope. Cx43 immunoreactivity at the gap junctions in each image was quantified and normalized to the area of the respective cardiomyocyte using Image-Pro Plus 6.0 (Media Cybernetics, Bethesda, MA, USA). The relative Cx43 immunoreactivity levels of 18M, OVX or OVX+E2 rats that were presented in the column were normalized to 6M or Sham group.

Cells were seeded on 15‐mm glass coverslips (Paul Marienfeld GmbH & Co. KG, Lauda‐Königshofen, Germany) to proper confluent, fixed with 4% paraformaldehyde for 10 min, and permeabilized with 0.05% Triton X for 5 min. The fixed cells were incubated with blocking buffer (3% BSA in PBS) at room temperature for 1 h, with primary antibodies (diluted in 1% BSA in PBS) overnight at 37 °C, and then incubated with secondary antibodies for 1 h at room temperature in the dark. The primary antibodies used include anti‐E‐cadherin (#610182) from BD Transduction Laboratories; antivimentin (#M7020) from Dako; and anti‐β‐Catenin (#8480) from Cell Signaling Technology (Danvers, MA, USA). Secondary antibodies are Alexa Fluor 488‐conjugated anti‐mouse (#A11029) and Alexa Fluor 594‐conjugated anti‐mouse (#A11032) from Invitrogen (Carlsbad, CA, USA). For F‐actin staining, rhodamine phalloidin (#R415; Life Technologies) was used directly after blocking. The stained coverslips were mounted onto glass slides using Vectashield mounting medium with DAPI (#H‐1200) from Vector Laboratories (Burlingame, CA, USA). Images were taken using Nikon (Minato, Tokyo, Japan) A1R confocal microscope. To quantify immunofluorescence (IF) expression of E‐cadherin and vimentin, mean fluorescence intensity was measured by using the automated measurement function in the nikon software.

Immunocytochemistry was used to detect osteocalcin and aggrecan localization in control and scaffolds after 21 days of osteogenic and chondrogenic differentiations, respectively. Likewise, cells were also immunostained by neural-specific markers β-III tubulin and MAP2 after 6 days of neuronal induction. Cells were fixed, permeabilized, and blocked as mentioned earlier and incubated with Alexa Fluor 488-conjugated rabbit polyclonal anti-osteocalcin (1:100; Biospes, China) overnight at 4°C. Similarly, overnight incubations at 4°C with the antibodies rabbit polyclonal anti-aggrecan (1:100; Biospes), mouse monoclonal anti-β-III tubulin (1:100; Santa Cruz, USA), and mouse monoclonal anti-MAP2 (1:100; Santa Cruz) were followed by 4 hour incubation with iFluor® 488-conjugated anti-rabbit (1:200; Biospes), FITC-conjugated anti-mouse (1:200; Santa Cruz), and Alexa Fluor 594-conjugated anti-mouse (1:200; Invitrogen) secondary antibodies, respectively, at room temperature in darkness. After PBS washing, the coverslips were mounted on glass slides with DAPI ProLong Gold antifade solution (Invitrogen). All images were obtained using the same photographic parameters of exposure and speed in an inverted fluorescence microscope (Carl Zeiss) with Axio Vision 4.0 image analysis system.

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.
