Quantifying c-Kit+ Cells in Colon

After the mice of each group were sacrificed, the proximal colon was collected immediately, fixed with 10% formalin, embedded in paraffin, sectioned to a thickness of 5 mm, deparaffinized and submitted to hematoxylin and eosin (H&E, Sigma-Aldrich, Shanghai, China) staining. Immunohistochemistry was performed using a previously described method (Huang et al., 2019 (link)). Briefly, 3 μm sections were deparaffinized in xylene and rehydrated in graded alcohol. After quenching endogenous peroxidase activity and blocking non-specific binding, the sections were incubated with a rabbit monoclonal antibody [EPR22566-344] against c-Kit (Abcam, ab256345) overnight at 4°C and then incubated with the secondary antibody goat anti-rabbit IgG (H + L) HRP (ab0101, Abways) at room temperature for 30 min. Finally, the slides were incubated with reagents from the Avidin-Biotin Complex Kit (Vector Laboratories, Inc., Burlingame, USA) and a 3,3′-diaminobenzidine kit (Tiangen, China) according to the manufacturer’s instructions. Images were captured with a Nikon Ci-S microscope and Nikon DS-U3 imaging system. The proportion of c-Kit-positive cells in the colonic muscle layer was determined using an image analyzer (Image-Pro Plus 6.0, Media Cybernetics, Inc., Rockville, USA).

Western Blot Analysis of Mouse Proteins

Total proteins were extracted from mouse tissues or cells using RIPA Lysis Buffer (#P0013B; Beyotime), following the manufacturer's instructions. A total of 30 μg of protein from each sample were boiled at 100°C for 5 minutes, separated through SDS‐PAGE, and transferred onto PVDF membranes (Millipore). The membranes were blocked with 5% lipid‐free milk for 1‐2 hours, incubated with primary antibodies diluted in TBST for 2 hours at room temperature, washed with TBST and incubated with secondary antibodies for 1 hour at room temperature. Protein abundances were determined by development with enhanced chemiluminescence (ECL) substrates (Millipore). GAPDH was used as an internal standard. Primary antibodies targeting c‐Kit (#ab256345; Abcam), P65 (#ab16502; Abcam), p‐P65 (#ab86299; Abcam), AKT (#9272; CST), p‐AKT (#4060; CST) and GAPDH (#ab8245; Abcam) were applied.

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.
