Distribution of ZsGreen1 expression in the kidney following renal pelvis injection. Mice have been injected with ZsGreen1 messenger RNA or plasmid DNA by renal pelvis injection. At 24 h just after injection, the kidney tissues have been histologically analyzed with anti-ZsGreen1 antibody and CD324 (specified for tubular epithelial cells)-antibody staining. 7 of 11 Pharmaceutics 2021, 13, 1810 The stained sections were observed by confocal laser scanning microscopy.

Despite the fact that there were slight interindividual variations, there was no significant elevation of Cre and BUN levels right after the injection of mRNA compared considerable elevation of Cre and BUN levels immediately after the injection of mRNA or pDNAor pDNA with the sham-operated group (Figure four). Therefore, it truly is Therefore, it really is that the injection was safely compared together with the sham-operated group (Figure four). recommended suggested that the injection carried out, and also the injection injection volume (50 ) was within the limit to the renal was safely carried out, and thevolume (50 ) was within the tolerance tolerance limit to pelvis injection.injection. the renal pelvisFigure 4.

The blood was collected on day 1 injection of messenger RNA (mRNA) or plasmid DNA (pDNA). The blood was collected on day 1 and day 7 after the injection of naked pDNA, naked mRNA (Luc2), or mRNA-loaded polylplex nanomicelles. Serum Cre and BUN levels have been measured using a DRI-CHEM NX-700 analyser. Data are represented as mean + SD (n = 4).three.2.two. Histological Assessment right after Renal Pelvis Injection of Messenger RNA or Plasmid DNA The target kidney was assessed histologically 1 d right after the renal pelvis injection of naked DNA, naked mRNA, or mRNA-loaded nanomicelles, as well because the kidneys of sham-operated mice (Figure 5). Compared with the sham-operated mice, there had been some slight adjustments in the specimens of injection groups, like tubular dilatation, hyaline casts (head arrows in Figure 5), and mononuclear infiltration (circle location in Figure 5).
