Different osteogenic differentiation behavior of canine mesenchymal stem cells derived from bone marrow and dental pulp: the proteomics profile

ABSTRACT: Although various sources of cMSCs show similar characteristics, they are different in osteogenic potential due to their original cellular sources. Thus, this study was designed to globally explore and analyze the in vitro differentiation potential and behavior of canine bone-marrow derived mesenchymal stem cells (cBM-MSCs) and canine dental pulp stem cells (cDPSCs) toward osteogenic lineage. Global study of an in vitro osteogenic differentiation potential of the isolated cells was performed using proteomic-based analysis through mass spectrometry with dimethyl labelling method at day 7 and 14 post-induction, comparing with undifferentiated cells. The obtained results could be used as a comprehensive data and principal knowledge of the osteogenic differentiation potential of cBM-MSCs and cDPSCs in vitro and the trend of MSC-based tissue engineering for osteogenic regenerative therapy, concentrating on cMSCs application.

Utilization of canine mesenchymal stem cells (cMSCs) for regenerating incorrigible bone diseases has been introduced. However, cMSCs harvested from different sources showed distinct osteogenicity. To clarify this, comparative proteomics-based systems biology analysis was used to analyze osteogenic differentiation behavior by cMSCs harvested from bone marrow and dental pulp. The results illustrated that canine dental pulp stem cells (cDPSCs) contained superior osteogenicity comparing with canine ...[more]

Project description:We have previously reported that the deficiency of p53 alone or in combination with Rb (Rb-/- p53-/-) in adipose-derived MSCs (ASCs) promotes leiomyosarcoma-like tumors in vivo. Here, we hypothesized that the source of MSCs and/or the cell differentiation stage could determine the phenotype of sarcoma development. To investigate whether there is a link between the source of MSCs and sarcoma phenotype, we generated p53-/- and Rb-/-p53-/- MSCs from bone marrow (BM-MSCs). Both genotypes of BM-MSCs initiated leiomyosarcoma formation similar to p53-/- and Rb-/-p53-/- ASCs. In addition, gene expression profiling revealed a link between p53- or Rb-p53-deficient BM-MSCs and ASCs and muscle-associated sarcomagenesis. These data suggest that the tissue source of MSC does not seem a crucial factor in the development of a particular sarcoma phenotype. To analyze whether the differentiation stage defines the sarcoma phenotype, BM-MSCs and ASCs were induced to differentiate towards the osteogenic lineage, and both p53 and Rb were excised using Cre-expressing adenovectors at different stages along osteogenic differentiation. Regardless of the level of osteogenic commitment, the inactivation of Rb and p53 in BM-MSC-derived, but not in ASC-derived, osteogenic progenitors gave rise to osteosarcoma-like tumors which could be serially transplanted. This indicates that the osteogenic differentiation stage of BM-MSCs imposes the phenotype of in vivo sarcoma development, and that BM-MSC-derived osteogenic progenitors rather than undifferentiated BM-MSCs, undifferentiated ASCs or ASC-derived osteogenic progenitors, represent the cell of origin for osteosarcoma development. To analyse whether the BM-MSC and Fat-MSC (ASC) differentiation stage may define the sarcoma phenotype, RbloxP/loxPp53loxP/loxP BM-MSCs and ASCs were induced to differentiate towards the osteogenic lineage and both Rb and p53 were excised with adenoviral vectors expressing the Cre-recombinase gene (Ad-CMV-Cre) at different stages (day 0 and 10) along osteogenic differentiation. NSG mice were inoculated subcutaneously with 5M-CM-^W10^6 mutant cells. Animals were killed when tumors reached 1 cm3 or 150 days after infusion. Some of the obtained tumors were mechanically disaggregated to establish ex vivo MSC-transformed cell lines. Gene expression analysis was performed using: WT BM-MSCs and ASCs, Rb-/-p53-/- BM-MSCs and ASCs previously differentiated to the osteogenic lineage for 10 days and a tumor cell line derived from p53-/-Rb-/- BM-MSC differentiated to the osteogenic lineage for 10 days.

BM-MSC and ASC cultures were established from 3 mouse strains: (a) WT, (b) p53loxP/loxP and (c) p53loxP/loxP RbloxP/loxP. The corresponding mutant cells were generated by excision of the LoxP-flanked sequences by infection of all MSC cultures with adenoviral vectors expressing the Cre-recombinase gene (Ad-CMV-Cre). NSG mice were inoculated subcutaneously with 5×10^6 mutant cells. Animals were killed when tumors reached 1 cm3 or 150 days after infusion. Some of the obtained tumors were mechanically disaggregated to establish ex vivo MSC-transformed cell lines. Gene expression analysis was performed using BM-MSCs and ASCs from all genotypes, as well as tumor cell lines derived from p53-/- and p53-/-Rb-/- BM-MSC and ASC cultures.
