The present invention relates to compositions and methods for inducing intestinal stem cell homeogenesis and/or regeneration within intestinal tissue expressing Robo1 through administration of a Rspo1 agent and a Slit2 agent. Administration of such agents results in, for example, binding of the Rspo1 agent and Slit2 agent with Robo1, resulting in, for example, binding of the CC3 motif of Robo1 with LRP6, resulting in phosphorylation of LRP6, and ultimately, induction of intestinal stem cell homeogenesis and/or regeneration. In certain embodiments, such administration of a Rspo1 agent and a Slit2 agent is used to protect and/or prevent intestinal tissue damage resulting from exposure to an intestinal tissue damaging event (e.g., radiation). The agents and related compositions additionally find use in diagnostic and research settings.
