Description

RS-246204 is a R-spondin-1 substitute compound that is able initiate small intestinal organoids without the use of the R-spondin-1 protein.

In Vitro

R-spondin-1 protein is added at a high concentration for the initiation and maintenance of the organoids. RS-246204 is a R-spondin-1 substitute that could promote the initial formation and growth of enteroids in the medium without R-spondin-1. The enteroids grown with RS-246204 had a similar differentiation capacity as well as self-renewal capacity as the enteroids grown with R-spondin-1. Furthermore, the RS-246204-derived enteroids could successfully produce the forskolin induced swelling and the organoid based epithelial to mesenchymal transition model[1].

In Vivo

RS-246204 significantly increased BrdU+ cells and body weight in the DSS induced colitis model. These results suggest that RS-246204 activates the R-spondin dependent pathway in Lgr5 stem cells, thereby enhancing proliferation or the anti-apoptotic effect, promoting regeneration of the intestinal epithelium and reducing the disease severity[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 0.5 mg/mL (1.47 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 0.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 0.5 mg/mL (1.47 mM); Clear solution

    This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Mice[1]

Seven-week-old C57Bl/6 mice are given a 2.5% dextran sulfate sodium treatment in drinking water for 5 days. RS-246204 (10 mg/kg in DMSO) is administered intraperitoneally at the end of the DSS exposure. The RS-246204 treatment is repeated every 24 h for 5 days. Daily assessments of disease activity are performed including measuring body weight and evaluating stool consistency. The mice are sacrificed the next day after the last injection of RS-246204. BrdU (50 mg/kg in saline) is administered intraperitoneally 24 hours before sacrifice[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
