Abstract
AIM The aim of this study was to compare the properties of stem cells derived from "inflamed" and healthy periodontal ligament (PDL) tissues from patient-matched groups. MATERIAL AND METHODS Patient-matched stem cells derived from root-attached "inflamed" and healthy PDL tissues from six donors, termed I-PDLSCs and H-PDLSCs, respectively, were investigated with regard to their stem cell properties, immunomodulatory effects and capacity to form robust cell sheets for therapeutic applications. RESULTS We found that cells derived from both sources exhibited typical mesenchymal stem cell (MSC) characteristics. However, compared with H-PDLSCs, I-PDLSCs demonstrated an increased capacity to proliferate, a greater potential to migrate and a decreased capacity to differentiate into osteoblasts in vitro. When I-PDLSCs and H-PDLSCs were co-cultured with peripheral blood mononuclear cells, the MSCs derived from "inflamed" PDL tissues exhibited impaired immunomodulation. Although I-PDLSCs led to increased collagen type I, periostin and integrin β1 content in the matrix, the cell sheets formed by I-PDLSCs were dysfunctional due to their impaired osteogenic/chondrogenic differentiation and tissue regeneration. CONCLUSIONS These data provide additional evidence that I-PDLSCs are functionally compromised compared with H-PDLSCs. Nonetheless, their dominant abundance in the available tissues indicates that stem cells derived from damaged teeth extracted due to periodontitis warrant further exploration.

Enhanced angiogenesis in ischemic skeletal muscle after transplantation of cell sheets from baculovirus-transduced adipose-derived stromal cells expressing VEGF165. Stem Cell Res Ther 2015; 6:204. [PMID: 26503601 PMCID: PMC4620646 DOI: 10.1186/s13287-015-0199-6] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2015] [Revised: 09/28/2015] [Accepted: 10/06/2015] [Indexed: 12/15/2022] Open
Abstract
Introduction Cell therapy using adipose-derived stromal cells (ADSC) is an intensively developing approach to promote angiogenesis and regeneration. Administration technique is crucial and among others minimal constructs - cell sheets (CS) have certain advantages. Delivery of CS allows transplantation of cells along with matrix proteins to facilitate engraftment. Cells’ therapeutic potential can be also increased by expression of proangiogenic factors by viral transduction. In this work we report on therapeutic efficacy of CS from mouse ADSC transduced to express human vascular endothelial growth factor 165 a/a isoform (VEGF165), which showed potency to restore perfusion and protect tissue in a model of limb ischemia. Methods Mouse ADSC (mADSC) isolated from C57 male mice were expanded for CS formation (106cells per CS). Constructs were transduced to express human VEGF165 by baculoviral (BV) system. CS were transplanted subcutaneously to mice with surgically induced limb ischemia and followed by laser Doppler perfusion measurements. At endpoint animals were sacrificed and skeletal muscle was evaluated for necrosis and vessel density; CS with underlying muscle was stained for apoptosis, proliferation, monocytes and blood vessels. Results Using BV system and sodium butyrate treatment we expressed human VEGF165 in mADSC (production of VEGF165 reached ≈ 25-27 ng/ml/105 cells) and optimized conditions to ensure cells’ viability after transduction. Implantation of mock-transduced CS resulted in significant improvement of limb perfusion, increased capillary density and necrosis reduction at 2 weeks post-surgery compared to untreated animals. Additional improvement of blood flow and angiogenesis was observed after transplantation of VEGF165-expressing CS indicating enhanced therapeutic potential of genetically modified constructs. Moreover, we found delivery of mADSC as CS to be superior to equivalent dose of suspended cells in terms of perfusion and angiogenesis. Histology analysis of extracted CS detected limited proliferation and approximately 10 % prevalence of apoptosis in transplanted mADSC. Significant vascularization of CS and infiltration by monocytes were found in both – BV-transduced and control CS indicating graft and host interaction after transplantation. Conclusions Delivery of ADSC by subcutaneous transplantation of CS is effective for stimulation of angiogenesis and tissue protection in limb ischemia with a potential for efficacy improvement by BV transduction to express VEGF165.

Age-related decline in the matrix contents and functional properties of human periodontal ligament stem cell sheets. Acta Biomater 2015; 22:70-82. [PMID: 25922305 DOI: 10.1016/j.actbio.2015.04.024] [Citation(s) in RCA: 45] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2014] [Revised: 04/16/2015] [Accepted: 04/19/2015] [Indexed: 02/08/2023]
Abstract
In this study, periodontal ligament (PDL) stem cells (PDLSCs) derived from different-aged donors were used to evaluate the effect of aging on cell sheet formation. The activity of PDLSCs was first determined based on their colony-forming ability, surface markers, proliferative/differentiative potentials, senescence-associated β-galactosidase (SA-βG) staining, and expression of pluripotency-associated transcription factors. The ability of these cells to form sheets, based on their extracellular matrix (ECM) contents and their functional properties necessary for osteogenic differentiation, was evaluated to predict the age-related changes in the regenerative capacity of the cell sheets in their further application. It was found that human PDLSCs could be isolated from the PDL tissue of different-aged subjects. However, the ability of the PDLSCs to proliferate and to undergo osteogenic differentiation and their expression of pluripotency-associated transcription factors displayed age-related decreases. In addition, these cells exhibited an age-related increase in SA-βG expression. Aged cells showed an impaired ability to form functional cell sheets, as determined by morphological observations and Ki-67 immunohistochemistry staining. Based on the production of ECM proteins, such as fibronectin, integrin β1, and collagen type I; alkaline phosphatase (ALP) activity; and the expression of osteogenic genes, such as ALP, Runt-related transcription factor 2, and osteocalcin, cell sheets formed by PDLSCs derived from older donors demonstrated a less potent osteogenic capacity compared to those formed by PDLSCs from younger donors. Our data suggest that the age-associated decline in the matrix contents and osteogenic properties of PDLSC sheets should be taken into account in cell sheet engineering research and clinical periodontal regenerative therapy.
