Fig 1: Gene expression analysis to identify candidate genes encoding novel host environment factors supporting grafted neurons. (A) Schematic flowchart describing the selection process of candidate genes. (B-H) Gene expression levels of the 7 candidate genes selected, as represented by count per million, for (B) Apod, (C) Ctsd, (D) Ctss, (E) Lyz2, (F) Spp1, (G) Grn, and (H) Sparc. Data are represented as the mean ± SEM, n = 4, Mann-Whitney test; *P < .05.
