a Workflow: analysis of Ntn1flox/flox and CAGGS:CreERT2; Ntn1flox/flox mice 8 weeks after Cre induction for (be). b Representative flow cytometry plots of the LSK population of Ntn1flox/flox and Ntn1ΔCAGGS/ΔCAGGS mice. c Frequencies of bone marrow HSCs in Ntn1flox/flox and Ntn1ΔCAGGS/ΔCAGGS mice; n = 7 (flox)–10 (∆CAGGS), two independent experiments. d Cell cycle phase of HSCs derived from Ntn1flox/flox and Ntn1ΔCAGGS/ΔCAGGS mice; n = 8 (flox) and 10 (∆CAGGS), two independent experiments. e Relative expression of quiescence and activation related genes in HSCs derived from Ntn1flox/flox and Ntn1ΔCAGGS/ΔCAGGS mice; n = 6 (flox)–9 (∆CAGGS), two independent experiments. f Frequencies of bone marrow HSCs in Ntn1flox/flox and Ntn1ΔCAGGS/ΔCAGGS mice 5 months after Cre induction; n = 8 (∆CAGGS) and 12 (flox), three independent experiments. g Cell cycle phase of HSCs derived from Ntn1+/LSL-Rosa26-Ntn1 and Ntn1-OE mice; n = 8 (∆CAGGS) and 12 (flox), three independent experiments. h Workflow: competitive transplantation of CAGGS:CreERT2, Ntn1ΔCAGGS/ΔCAGGS and Ntn1-OE mice 5 months after Cre induction, analysed in (ik). i Representative FACS plots of peripheral blood leucocytes pre-gated on CD45+ cells at 16 weeks after transplantation. j Peripheral blood CD45.2+ chimerism during competitive transplantations; n = 13 (OE)–14 (Cre/∆CAGGS), two independent experiments. Analysis was done with two-way-ANOVA, multiple comparison with LSD Fisher’s test. k Bone marrow HSC CD45.2+ chimerism after 16 weeks of competitive transplantation; n = 12 (Cre)–13 (∆CAGGS/OE), two independent experiments. l Workflow: transplantation of 200 HSCs sorted from CAGGS:CreERT2 and Ntn1ΔCAGGS/ΔCAGGS mice at 5 months after Cre induction. m Frequencies of bone marrow HSCs 8 weeks transplantation; n = 6. For all panels, ±SD is shown. n indicates biological replicates. P value was determined by two-tailed t test unless stated otherwise. Source data are provided as a Source Data file.
