Over Time

Adipose tissue presents an appealing alternative to bone marrow as a source of mesenchymal stem cells (MSC). However, in order to enhance cell proliferation and differentiation, 3-dimensional (3-D) culture may be required. A 3-D culture has benefits due to its more in vivo-like environment. Further, to form a functional tissue, a scaffold material is required to ensure proper shape and allow for efficient delivery of nutrients and growth factors. Alginate, a resorbable hydrogel, is a potential injectable scaffold for fat and bone tissue engineering due to its high biocompatibility, gelation with calcium and slow dissolution in a physiologic environment. In the present study, we examined the viability, gene expression and morphology of MSC, isolated from porcine adipose (ADSC) and bone marrow (BMSC), during osteogenic and adipogenic differentiation in a 3D alginate hydrogel environment for 0, 7 and 14 days (d). ADSC and BMSC were infused into alginate hydrogels, which polymerized upon the addition of Ca+2 ions. Both stem cell types were differentiated into osteoblasts using 0.1 μm dexamethasone, 10 mm beta glycerophosphate and 50 μm ascorbic acid, whereas adipocytes were differentiated using 10 μm insulin, 1 μm dexamethasone, and 0.5 mm IBMX. Osteogenic differentiation was confirmed using alkaline phosphatase, Von Kossa, and alizarin red S staining and adipogenic differentiation was confirmed using Oil Red O. Cell viability and proliferation was quantified using the MTT assay. Gene expression was measured using qPCR. The morphology of ADSC and BMSC differentiated toward osteogenic lineages changed with both cell types forming osteogenic nodules over time. The nodules formed by ADSC were larger in diameter than those formed by BMSC. Unlike the osteogenic cells that formed nodules, the ADSC and BMSC differentiated into adipogenic cells showed no significant changes in cell size or aggregation. Gene expression results indicated increased PPARG expression in BMSC with time whereas ADSC showed a peak of expression on day 7 and then decreased. ADSC showed increased (14-fold) PPRG expression when compared with BMSC. ADSC had 160-fold less expression of ALP than BMSC. BMSC showed a 16-fold higher expression level of BGLAP than ADSC. ADSC showed a 15.8% higher expression than BMSC for COL1a1. Both ADSC and BMSC showed similar trends SPARC expression, but BMSC had a 12-fold higher expression of SPP1 than ADSC. In summary, both types of mesenchymal stem cells successfully differentiated into both lineages and maintained viability in the hydrogel over time. In conclusion, alginate is a viable scaffold material for the differentiation of mesenchymal stem cells for tissue engineering applications. These results allow for future studies using the pig as an in vivo fat and bone tissue engineering model. This research was supported by the Illinois Regenerative Medicine Institute.

Tissue Repair And Regeneration

Mesenchymal stem cells (MSCs) exhibit high proliferation and self-renewal capabilities and are critical for tissue repair and regeneration during ontogenesis. They also play a role in immunomodulation. MSCs can be isolated from a variety of tissues and have many potential applications in the clinical setting. However, MSCs of different origins may possess different biological characteristics. In this study, we performed a comprehensive comparison of MSCs isolated from bone marrow and skin (BMMSCs and SMSCs, resp.), including analysis of the skin sampling area, separation method, culture conditions, primary and passage culture times, cell surface markers, multipotency, cytokine secretion, gene expression, and fibroblast-like features. The results showed that the MSCs from both sources had similar cell morphologies, surface markers, and differentiation capacities. However, the two cell types exhibited major differences in growth characteristics; the primary culture time of BMMSCs was significantly shorter than that of SMSCs, whereas the growth rate of BMMSCs was lower than that of SMSCs after passaging. Moreover, differences in gene expression and cytokine secretion profiles were observed. For example, secretion of proliferative cytokines was significantly higher for SMSCs than for BMMSCs. Our findings provide insights into the different biological functions of both cell types.

Marrow Mesenchymal Stem Cells

Biocompatible scaffolding materials play an important role in bone tissue engineering. This study sought to develop and characterize a nano-hydroxyapatite (nHA)/collagen I (ColI)/multi-walled carbon nanotube (MWCNT) composite scaffold loaded with recombinant bone morphogenetic protein-9 (BMP-9) for bone tissue engineering by in vitro and in vivo experiments. The composite nHA/ColI/MWCNT scaffolds were fabricated at various concentrations of MWCNTs (0.5, 1, and 1.5% wt) by blending and freeze drying. The porosity, swelling rate, water absorption rate, mechanical properties, and biocompatibility of scaffolds were measured. After loading with BMP-9, bone marrow mesenchymal stem cells (BMMSCs) were seeded to evaluate their characteristics in vitro and in a critical sized defect in Sprague-Dawley rats in vivo. It was shown that the 1% MWCNT group was the most suitable for bone tissue engineering. Our results demonstrated that scaffolds loaded with BMP-9 promoted differentiation of BMMSCs into osteoblasts in vitro and induced more bone formation in vivo. To conclude, nHA/ColI/MWCNT scaffolds loaded with BMP-9 possess high biocompatibility and osteogenesis and are a good candidate for use in bone tissue engineering.

Marrow Mesenchymal Stem Cells

Abnormal gene expression is frequently observed in nuclear transfer (NT) embryos and is one of the suggested causes of the low success rates of this approach. Recent study has suggested that adult stem cells may be better donor cells for NT, as their less differentiated state may ease epigenetic reprogramming by the oocyte (Kato et al. 2004 Biol. Reprod. 70, 415-418). In the present study, we investigated the expression profile of some selected genes involved in the development of the pre-implantation embryos of in vivo- and NT-derived origin using bone marrow mesenchymal stem cells (MSCs) and porcine fetal fibroblasts (pFF) as donors. Isolated population of MSCs from porcine bone marrow were characterized by cell-surface antigen profile (CD13pos, CD105pos, CD45neg, and CD133neg) and by their extensive consistent differentiation to multiple mesenchymal lineages (adipocytic, osteocytic and chondrocytic) under controlled in vitro conditions (Pittenger et al. 1999 Science 284, 143-147). Primary cultures of pFF from a female fetus at <30 days of gestation were established. for NT, donor cells at 3-4 passages were employed. Embryos cloned from MSCs showed enhanced developmental potential compared to pFF cloned embryos, indicated by higher rates of blastocyst formation (15.3% � 4.8 and 9.0% � 3.9, respectively) and total cell number (31.5 � 7.2 and 20.5 � 5.4, respectively) in Day 7 blastocysts. Total RNA was extracted from pools (triplicates) of 10 embryos each of 8-cell, morula, and blastocyst stages of in vivo and NT origin using Dynabeads� mRNA DIRECT" kit (Dynal, Oslo, Norway). Reverse transcription was performed with a Superscript" III cDNA synthesis kit (Invitrogen, Carlsbad, CA, USA). Real-time PCR was performed on a Light cycler� using FastStart DNA Master SYBR Green I (Roche Diagnostics, Mannheim, Germany). The expression profiles of genes involved in transcription (Oct-4, Stat3), DNA methylation (Dnmt1), de novo methylation (Dnmt3a), histone deacetylation (Hdac2), anti-apoptosis (Bcl-xL), and embryonic growth (Igf2r) were determined. The mRNA of H2a was employed to normalize the levels. Significant differences (P < 0.05) in the relative abundance of Stat3, Dnmt1, Dnmt3a, Bcl2, and Igf2r were observed in pFF NT embryos compared with in vivo-produced embryos, whereas embryos derived from MSCs showed expression patterns similar to those of in vivo-produced embryos. However, Oct-4 and Hdac2 revealed similar expression profiles in NT- and in vivo-produced embryos. These results indicate that MSC-derived NT embryos had enhanced embryonic development and their gene expression pattern more closely resembled that of in vivo-produced embryos. Hence, less differentiated MSCs may have a more flexible potential in improving the efficiency of the porcine NT technique.

Mesenchymal stem cells derived from human bone marrow (hBM-MSCs) are utilized in tendon tissue-engineering protocols while extra-embryonic cord-derived, including from Wharton’s Jelly (hWJ-MSCs), are emerging as useful alternatives. To explore the tenogenic responsiveness of hBM-MSCs and hWJ-MSCs to human Growth Differentiation Factor 5 (hGDF-5) we supplemented each at doses of 1, 10, and 100 ng/mL of hGDF-5 and determined proliferation, morphology and time-dependent expression of tenogenic markers. We evaluated the expression of collagen types 1 (COL1A1) and 3 (COL3A1), Decorin (DCN), Scleraxis-A (SCX-A), Tenascin-C (TNC) and Tenomodulin (TNMD) noting the earliest and largest increase with 100 ng/mL. With 100 ng/mL, hBM-MSCs showed up-regulation of SCX-A (1.7-fold) at Day 1, TNC (1.3-fold) and TNMD (12-fold) at Day 8. hWJ-MSCs, at the same dose, showed up-regulation of COL1A1 (3-fold), DCN (2.7-fold), SCX-A (3.8-fold) and TNC (2.3-fold) after three days of culture. hWJ-MSCs also showed larger proliferation rate and marked aggregation into a tubular-shaped system at Day 7 (with 100 ng/mL of hGDF-5). Simultaneous to this, we explored the expression of pro-inflammatory (IL-6, TNF, IL-12A, IL-1β) and anti-inflammatory (IL-10, TGF-β1) cytokines across for both cell types. hBM-MSCs exhibited a better balance of pro-inflammatory and anti-inflammatory cytokines up-regulating IL-1β (11-fold) and IL-10 (10-fold) at Day 8; hWJ-MSCs, had a slight expression of IL-12A (1.5-fold), but a greater up-regulation of IL-10 (2.5-fold). Type 1 collagen and tenomodulin proteins, detected by immunofluorescence, confirming the greater protein expression when 100 ng/mL were supplemented. In the same conditions, both cell types showed specific alignment and shape modification with a length/width ratio increase, suggesting their response in activating tenogenic commitment events, and they both potential use in 3D in vitro tissue-engineering protocols.

The pig is an ideal species for use in tissue engineering studies targeted towards repair of bone and cartilage defects. Novel collagen-glycosaminoglycan hydrogel (CG) scaffolds have shown promise for supporting bone and cartilage growth from mesenchymal stem cells. In order to determine the suitability of these scaffolds for use in porcine model systems for bone and cartilage tissue engineering, we have begun to investigate the behaviour of porcine mesenchymal stem cells on this material. The purpose of this study was to determine whether mesenchymal stem cells from adipose (ASC) and bone marrow (BMSC) form bone on a CG scaffold material. Primary BMSC and ASC from 6-month-old Yorkshire pigs were cultured in Dulbecco’s Modified Eagle’s Medium (DMEM) with 10% fetal bovine serum. The ASC and BMSC were then trypsinized at passage 4 or 5 and used to seed ~4-mm-diameter CG scaffolds with 2 million cells/scaffold. Scaffolds were seeded by suspending the cells in medium that had been equilibrated for 30 min, and then placing the CG scaffold into the medium. This method of seeding was determined to be most effective in previous experiments. Scaffolds were then cultured for 7 days in DMEM followed by 21 days in osteogenic media. At the conclusion of the incubation period, the diameter of the scaffolds was measured, and they were fixed with 4% paraformaldehyde and cryosectioned. Then, 10-µm sections were stained with Alizarin Red to assay for mineralization, a hallmark of osteogenic differentiation. Both ASC- and BMSC-loaded scaffolds showed Alizarin Red staining throughout the section after incubation, demonstrating that both undergo osteogenesis on the scaffold material (n = 4). During osteogenic differentiation, scaffolds seeded with both ASC and BMSC showed a decrease in diameter. Unseeded scaffolds showed no decrease in size when in media. The BMSC scaffolds demonstrated a more extensive decrease in size than ASC. The average diameter of ASC loaded scaffolds after differentiation was 2.49 ± 0.39 mm, and that of BMSC-loaded scaffolds was 1.47 ± 0 0.18 mm (n = 3, P < 0.05, Student’s t-test). This suggests a differential ability of ASC and BMSC to break down and metabolize the scaffold matrix, and may indicate that one cell type may be preferable to the other for repairing osteogenic defects using these scaffolds. Current experiments underway will analyse expression of matrix-degrading enzymes to determine the source of the difference between cell types in scaffold shrinkage during differentiation. We will also quantify mineralization in ASC- v. BMSC-loaded scaffolds and assay gene expression of osteogenic markers to determine if there is a difference in osteogenic potential between sources of mesenchymal stem cells on these scaffolds.

Previous data support adipose-derived stem cells as an alternative to bone marrow as a source of adult stem cells for therapeutic purposes. The aim of the present study was to directly compare the transcriptome of adipose-derived (ADSC) and bone marrow-derived (BMSC) mesenchymal stem cells prior to differentiation and during in vitro osteogenic and adipogenic differentiation. The ADSC and BMSC were harvested from 3 adult pigs and differentiated in vitro into adipocytes and osteocytes for up to 4 weeks. Prior to differentiation and at differentiation day 2, 7, and 21, cells were harvested and RNA extracted for transcriptomics analysis by a 13 263 oligo 70-mers array (Sus scrofa AROS V1.0 with extension; Operon). Data were normalized by Lowess and statistical analysis was run using ANOVA with Benjamini-Hochberg false discovery rate (FDR) correction. Data mining was carried out using Ingenuity Pathway Analysis and David. Using an FDR of <0.05 for overall tissue effect and a post-hoc correction of P < 0.001, we observed 65 differentially expressed genes (DEG) between ADSC and BMSC before starting differentiation (0.66% of unique genes in the array). Functional analysis uncovered significant enrichment of extracellular matrix genes with direct roles in cell adhesion, migration, movement, and morphology. When the interaction cell type × differentiation × time was assessed, we observed >2 000 DEG with an FDR <0.05. This large number was mostly due to time effects. When pair-wise comparisons between cell types for each time point during the same differentiation were performed (post-hoc P < 0.001), we observed a strikingly low number of DEG. The number of DEG was lower between cell types in osteogenic (<100 DEG) compared with adipogenic (<200 DEG) differentiation. We observed significant enrichment (FDR-corrected P-value cut-off <0.05) of functions related to metabolism, antigen presentation, angiogenesis, and cell cycle in both differentiation conditions. We also observed an overall greater induction of the enriched functions in ADSC and a decrease in BMSC during adipogenic differentiation and the opposite during osteogenic differentiation except for metabolism, which appeared to be larger in ADSC in all cases. Among the significant enriched functions of DEG between the 2 differentiations, we observed enrichment of genes involved in metabolism, cell death, cell-to-cell signalling, and antigen presentation in ADSC during adipogenic compared with osteogenic differentiation. In BMSC we observed enrichment of functions related to cell death, antigen presentation, and lipid metabolism in osteogenic v. adipogenic differentiation. Overall data uncovered a high similarity at the transcriptional level between ADSC and BMSC both prior to differentiation and during differentiation. Those data support ADSC being particularly similar to BMSC. This work was support by the Illinois Regenerative Medicine Institute (IDPH # 63080017).

Collagen type I and tenomodulin proteins, detected by immunofluorescence, confirming the greater protein expression when 100 ng/mL were supplemented. In the same conditions, both cell types showed specific alignment and shape modification (fibroblast-like) with a Lenght/Width ratio increase at value higher than 1, suggesting their response in activating tenogenic commitment events, and they both potential use in 3D in vitro tissue engineering protocols.
