16s rDNA data of fecal samples (30 samples from 5 groups)

Fecal microbiota transplantation from young donor mice rejuvenates hematopoietic stem cell in aged recipients by suppressing inflammatory signals while modulating gut microbiota and metabolites. The gut microbiota from healthy young donor mice (7-week-old) or aged donor mice (24-month-old) were transplanted into aged (24-month-old) recipient mice (FMT-young and FMT-aged group), separately. Aged mice treated with antibiotics (Antibiotics group), normal control aged mice (NC-aged group) and normal control young mice (NC-young group) served as experimental controls.
