The authors wish to provide clarifications and corrections to some inaccuracies in the published paper. Incomplete data was reported for the number of mice in each experimental group. The n for each group is provided in the following revised figure legend for Fig 2, along with clarification that 1.0 on the y-axis corresponds to 100% survival:

There was an error in statistical comparisons for the survival study due to the use of incorrect data on the number of mice in some groups. When the correct n-numbers for each experimental group are considered, the P values of Table 1 should be revised. Additionally, NA-BMCs are mislabelled as “naSCs” in one entry of the table. A corrected Table 1 is provided here.

We also provide a revised sentence for the Abstract with corrected n as follows: “Syngeneic NA-BMCs protected 83% of mice from death (n = 6, CD4+ donor chimerism of 5.8±2.4% [day 40], P < .001).”

All other data analysis employed the correct n numbers and is unaffected by this correction.

We also wish to clarify the statistical tests used to analyse the data by adding the following sentence to the Methods section on Statistical Analysis: “Analysis of survival curves was done using the log-rank test, analysis of other parameters with t-tests, the Mann–Whitney U test or the Holm-Sidak test.”

Finally, we provide additional information regarding the survival study as follows: mice were humanely euthanized by CO2 inhalation upon meeting certain criteria based on weight, mobility, texture of the fur, attitude, and skin appearance.

We apologize for any inconvenience resulting from the errors. These corrections do not change any conclusions or statements that are given in the publication.
