Cells were grown on 35-mm cell culture dishes with glass bottoms (NEST, Wuxi, China). Cells were fixed with 4% paraformaldehyde for 30 min. Fixed cells were washed and permeabilized with 0.1% Triton X-100 for 10 min. Cells were blocked with goat serum for 30 min and incubated with the anti-β-catenin antibody (1:100, 8480S, CST) overnight at 4 °C. After washing with PBS, the cells were subsequently incubated with Alexa Fluor® 488-conjugated anti-rabbit IgG antibody (1:1000, ab150077, Abcam) for 1 h. The nuclei were stained with DAPI (62248, Thermo Scientific). Images were acquired using a Zeiss LSM710 confocal microscope (Zeiss, Germany) at 400× magnification.

The sampled fetus or placenta tissues were frozen in OTC compound in cryomolds. On the other hand, sampled skeletal muscles were fixed on a corkboard with tragacanth gum and then frozen in isopentane at the temperature of liquid nitrogen. 8-μm-thick cryo-tissue sections were prepared using a cryostat, fixed with acetone for 5 min, and subjected to immunofluorescence staining as follows. After washing with PBS, tissue sections were incubated with 0.5% Triton-X (Sigma-Aldrich) in PBS for 10 min for permeabilization, washed with PBS, blocked using Blocking One Histo (NACALAI TESQUE, Kyoto, Japan) for 15 min, incubated with primary antibodies (rabbit anti-GFP and mouse anti-dystrophin, 1:100 diluted, Abcam, Cambridge, UK), washed, and incubated with Alexa-Fluor 488-conjugated anti-rabbit IgG antibody (1:200 diluted, Abcam) and Alexa-Fluor 588-conjugated anti-mouse IgG antibody. The immunostained tissue sections were observed under a confocal laser scanning fluorescence microscope (FV1200, Olympus, Tokyo, Japan) and Cell Sens Standard software (FV1-ASW, Olympus).

One month after dorsal root crush injury, rats were euthanized with pentobarbital sodium and perfused with 4% PFA. Under a stereomicroscope, spinal cords with attached roots and DRG tissues were collected from perfused rats. Subsequently, tissues were postfixed in 4% PFA for 24 h, and cryoprotected in 30% sucrose (wt/vol) for at least 48 h at 4 °C. The tissues were then embedded in OCT (Sakura, Finetek, USA), cryosectioned using a cryostat, and mounted onto slides. Spinal cord and DRG tissues were cryosectioned at thicknesses of 25 µm and 15 μm, respectively. After blocking in 5% BSA with 0.1% Triton X-100 for 1 h, sections were incubated with primary antibodies at 4 °C overnight. Secondary antibodies were applied for 2 h at room temperature. The following primary antibodies were used: mouse anti-CGRP (1:1000; Abcam); rabbit anti-laminin (1:2000; Abcam); and IB4 conjugated with DyLight 649 (1:500; Vector). The corresponding secondary antibodies were used as follows: Alexa Fluor 488-conjugated anti-rabbit IgG antibody (1:1000; Abcam) and Alexa Fluor 594-conjugated anti-mouse IgG antibody (1:1000; Abcam). Images were acquired by confocal microscopy (Zeiss 710) and analyzed using ImageJ software.

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.
