Metabolomics comparison of leukopenic and non-leukopenic mice reveals additional microbial products that may support hematopoiesis. (A) Experimental schematic of stool and serum collection for metabolomics. (B) Metabolites of interest generated from nontargeted metabolomics of stool. (C) The top enriched LIPEA pathway results from the fecal metabolomics. (D) Metabolites of interest generated from nontargeted metabolomics of serum. (E) The top enriched LIPEA pathway results from the serum metabolomics. FC, fold change. *P < .05, **P < .01, ***P < .001.
