Mesenchymal stromal cells(MSC)have shown their benefits in graft-versus-host disease(GVHD), with five unsettled matters: 1) MSCs expansion in medium with Fetal Bovine Serum(FBS)and its risk of xenoreaction;2) The number of cells indicated for therapy that is relatively high, with the need to optimize the expansion, number and time wise;3) The utilization of third party donors;4) Culture passage number(P);and 5) Source of the cells. This study was designed to determine the superiority of the Platelet Lysates(PL)over FBS on the expansion of MSC, the optimal cell’ plating density and days between each pass, and to investigate if donor total nucleated cells(TNC)obtained from the washouts of discharged bags and filters of hematopoietic stem cell transplantation(HSCT)can be expanded to be used at clinical grade. TNC were removed, plated and after the first passage were cultivated in different concentrations with FBS or PL, and the number of days to reach 80% of confluence was observed. Next, cultures with the same plating density were fed either with PL or with FBS and after seven days counted to analyze how much they had grown in that period. The proliferation of mesenchymal stromal cells in the presence of PL and SFB was averaged 11.88 and 2.5 times, respectively, in a period of 7 days. The highest concentration of plating cells using PL took less time to reach confluence as compared with the three lower ones. This study suggests that the PL is the best choice as a supplement to expand MSC and to allow the proliferation of enough number of MSC at P2 for clinical use.

Characteristics of Mesenchymal Stem Cells under Hypoxia

引用

CellBio 2013年第1期2卷 11-19页

作者： Bruna Amorin Ana Paula Alegretti vanessa de Souza Valim Annelise Martins Pezzi da Silva Maria aparecida Lima da Silva Felipe Sehn Lucia Silla Cell Technology Center Experimental Research Center Hospital de Clínicas de Porto Alegre-Porto AlegreRio Grande do Sul Brazil

Mesenchymal stem cells (MSC) are considered non-hematopoietic multipotent stem cells with self-renewal properties and the ability to differentiate into a variety of mesenchymal tissues. Optimal conditions for the culture of these cells have been the subject of investigation for several years. In particular, ideal oxygen tension levels have not been established in the literature. In physiological environments, oxygen tension may vary from 12% in peripheral blood to 1% in the deep zone of cartilage regions. In any case, oxygen tension is considerably lower in vivo when compared with the normal atmosphere of standard cell culture conditions (21%). The objective of this study was to review the literature available on MSC characteristics (cell cycle, survival, proliferation, differentiation, morphology, immunophenotype, cytogenetics) when cultured under hypoxic conditions. Our focus on optimal culture conditions is justified by the key role currently played by these cells in regenerative medicine.

Background: Mesenchymal stromal cells (MSC) are being tested for the treatment of immune diseases. MSC are present in several adult tissues which milieu may influence MSC behavior particularly under inflammatory conditions. Additionally, culture conditions also can modify cell function or state of activation. Methods: To address the influence of the MSC source on its characteristics, we studied a xenofree, platelet lysate supplemented MSC from dental pulp, adipose tissue and bone marrow, co-cultured with isolated T cells and PBMC subset, and studied the effect of culture animal or human supplements immunomodulatory effect. Results: All three sources were efficient in inhibiting T cells. Among all MSC sources, as also described by others, adipose MSC was capable to significantly induce Treg phenotype and decrease T CD8+. Furthermore, comparing fetal bovine serum and platelet lysate, results demonstrate that platelet lysate alone is capable to induce immunomodulatory phenotype. Additional studies have to be made to elucidate the PL immunomodulatory effect.
