Introduction: The olfactory neuro-epithelium has an intrinsic capability of renewal during lifetime provided by the existence of globose and horizontal olfactory precursor cells. Additionally, mesenchymal stromal olfactory cells also support the homeostasis of the olfactory mucosa cell population. Under in vitro culture conditions with Dulbecco modified eagle/F12 medium supplemented with 10% fetal bovine serum, tissue biopsies from upper turbinate have generated an adherent population of cells expressing mainly mesenchymal stromal phenotypic markers. A closer examination of these cells has also found co-expression of olfactory precursors and ensheathing cell phenotypic markers. These results were suggestive of a unique property of olfactory mesenchymal stromal cells as potentially olfactory progenitor cells.Objective: To study whether the expression of these proteins in mesenchymal stromal cells is modulated upon neuronal differentiation.Materials and methods: We observed the phenotype of olfactory stromal cells under DMEM/F12 plus 10% fetal bovine serum in comparison to cells from spheres induced by serum-free medium plus growth factors inducers of neural progenitors.Results: The expression of mesenchymal stromal (CD29+, CD73+, CD90+, CD45-), horizontal basal (ICAM-1/CD54+, p63+, p75NGFr+), and ensheathing progenitor cell (nestin+, GFAP+) proteins was determined in the cultured population by flow cytometry. The determination of Oct 3/4, Sox-2, and Mash-1 transcription factors, as well as the neurotrophins BDNF, NT3, and NT4 by RT-PCR in cells, was indicative of functional heterogeneity of the olfactory mucosa tissue sample. Conclusions: Mesenchymal and olfactory precursor proteins were downregulated by serum-free medium and promoted differentiation of mesenchymal stromal cells into neurons and astroglial cells.

Abstract Abstract 4737 Objective: To compare the difference of biological characteristics between human umbilical cord-derived mesenchymal stem cells (UC-MSC) cultured by serum free medium and fetal bovine serum-contained complete medium and to create a xenogeneic protein-free UC-MSC culture system. Methods: Healthy human umbilical cord segments were digested with collagenase. Umbilical cord-derived mesenchymal stem cells were cultured by serum free MesenCult-XF medium and FBS-based αMEM complete medium. We analysed the morphology, immunophenotype, expansion potential, trilineage differentiation potential, karyotype and immunosuppression of early passage of UC-MSC. Results: The average cell diameters of UC-MSC in suspension cultured by serum free medium and FBS-based medium are 26 (18–39) μm and 35 (20–61) μm, respectively. Cell expansion folds with serum free medium and FBS-based medium were (5.2±0.2) and (3.5±0.1) in the first five passage, respectively. The expansion potential of MSCs was significantly higher with serum free medium compared to FBS-based medium (P<0.05). A panel of markers as CD29, CD44, CD90, CD73, CD105 and HLA-ABC were expressed by human UC-MSC. Hematopoietic lineage markers CD34, CD45 and HLA-DR were not detectable on UC-MSC. The cpm were (4.57±0.14)×104, (2.04±0.16)×104 and(0.42±0.04)×104 when serum free medium cultured MSCs were added to the cultures at ratios MSCs/T cell of 1:100, 1:10 and 1:5. While the cpm were (4.57±0.14)×104, (2.04±0.16)×104 and(0.42±0.04)×104when serum free medium cultured UC-MSCs were added to the cultures. The immunosuppressive potential of serum free medium-cultured UC-MSC was higher than that of serum-contained medium cultured UC-MSC at three different ratios MSC/T cell (P<0.05). Conclusion Compare with serum-contained medium cultured early passage of UC-MSC, the cell diameter of serum free medium cultured MSCs was smaller and the expansion potential was higher. No xenogeneic proteins were presented in UC-MSC preparation when UC-MSC was cultured with serum free medium. Human UC-MSC suppresses T-cell proliferation in a dose-dependent manner. The immunosuppressive potential of UC-MSC was higher when cultured in serum free medium compared with FBS-based medium. Disclosures: No relevant conflicts of interest to declare.

Abstract Background: A long-term of peritoneal dialysis (PD) using a hypertonic PD solution (PDS) leads to patient’s peritoneal membrane (PM) injury, resulting in ultrafiltration failure (UFF) and PD drop-out. Our previous study shows that PD effluent-derived mesenchymal stromal cells (pMSCs) prevent the PM injury in normal rats after repeated exposure of the peritoneal cavity to a PDS. This study was designed to compare the cytoprotection between pMSCs and umbilical cord-derived MSCs (UC-MSCs) in the treatment of both PM and kidney injury in uremic rats with chronic PD.Methods: 5/6 nephrectomized (5/6Nx) Sprague Dawley rats were intraperitoneally (IP) injected Dianeal (4.25% dextrose, 10 mL/rat/d), and were treated with pMSCs or umbilical cord (UC)-MSCs (approximately 2×106/rat/wk, IP). Ultrafiltration was determined by IP injection of 30 mL of Dianeal (4.25% dextrose) with 1.5-h dewell time, and kidney failure by serum creatinine (SCr) and blood urea nitrogen (BUN). The structure of the PM and kidneys was assessed using histology. Gene expression was examined using quantitative reverse transcription PCR, and protein levels using flow cytometric and Western blot analyses.Results: We showed a slight difference in the morphology between pMSCs and UC-MSCs in plastic dishes, and significantly higher expression levels of stemness-related genes (NANOG, OCT4, SOX2, CCNA2, RAD21 and EXO1) and MSCs surface markers (CD29, CD44, CD90 and CD105) in UC-MSCs than those in pMSCs, but no difference in the differentiation to chondrocytes, osteocytes or adipocytes. pMSCs treatment was more effective than UC-MSCs in the protection of the MP and remnant kidneys in 5/6Nx rats from PDS-induced injury, which was associated with higher resistance of pMSCs than UC-MSCs to uremic toxins in culture, and more reduction of peritoneal mesothelial cell death by the secretome from pMSCs than from UC-MSCs in response to PDS exposure. The secretome from both pMSCs and UC-MSCs similarly inactivated NOS2 in activated THP1 cells.Conclusions: As compared to UC-MSCs, pMSCs may be more potently prevents PDS-induced PM and remnant kidney injury in this uremic rat model of chronic PD, suggesting that autotransplantation of ex vivo-expanded pMSCs may become a promising therapy for UFF and deterioration of remnant kidney function in PD patients.
