Are represented as mean SEM. Comparisons among 2 groups have been made utilizing a 2-tailed Student’s t test or Mann-Whitney test for parametric or nonparametric data, respectively. Comparisons amongst more than 2 groups were made using 1-way ANOVA followed by Tukey’s post hoc test or ANOVA for repeated measures followed by Tukey’s post hoc test as indicated for every single experiment. Information were regarded significant when P was less than 0.05. Study approval. All human tissue and cells applied in this study had been deidentified and IRB exempt. All breeding, surgical procedures, and animal experiments were authorized by the Institutional Animal Care and Use Committee at Vanderbilt University Health-related Center and performed in line with the Guide for the Care and Use of Laboratory Animals (National Academies Press, 2011).Author contributionsVDG, JYC, and DCN developed the research, performed experiments, analyzed data, and wrote the manuscript. NUC and ET designed research, performed experiments, and analyzed data. AEN and RSP supplied expertise and mice at the same time as reviewed the manuscript.
