Single-cell protein-expression map of bone marrow reveals stromal cell subset selection with stress

Project description:We identified CD73+ bone marrow stromal cells as hematopoietic niche candidates. To further validate our finding, we tested the functional role of CD73 during bone marrow transplantation using CD73-/- mice. We evaluated the transcriptome of transplanted WT hematopoietic stem and progenitor cells from WT or CD73-/- recipient mice and found changes in metabolic, cell cycle and signaling genes.

Predicting the therapeutic efficacy of MSC in bone tissue engineering using the molecular marker CADM1

Project description:Mesenchymal stromal cells (hMSCs) are advancing into the clinic but the therapeutic efficacy of hMSCs faces the problem of donor variability. In bone tissue engineering, no reliable markers have been identified which are able to predict the bone-forming capacity of hMSCs prior to implantation. To this end, we isolated hMSCs from 62 donors and characterized systematically their in vitro lineage differentiation capacity, gene expression signature and in vivo capacity for ectopic bone formation. Our data confirms the large variability of in vitro differentiation capacity which did not correlate with in vivo ectopic bone formation. Using DNA microarray analysis of early passage hMSCs we identified a diagnostic bone-forming classifier. In fact, a single gene, CADM1, strongly correlated with the bone-forming capacity of hMSCs and could be used as a reliable in vitro diagnostic marker. Furthermore, data mining of genes expressed correlating with in vivo bone formation represented involvement in neurogenic processes and Wnt signaling. We will apply our data set to predict therapeutic efficacy of hMSCs and to gain novel insight in the process of bone regeneration. Our bio-informatics driven approach may be used in other fields of cell therapy to establish diagnostic markers for clinical efficacy.

Human Bone Marrow Stromal Cells cultured on polymer scaffolds with varied properties

Project description:Microarray analysis was used to evaluate expression differences from a single donor human bone marrow stromal cells (hBMSCs) as a function of varied polymer-based tissue engineering scaffolds. The results revealed that gene expression patterns of hBMSCs grouped according to scaffold. A library of scaffolds prepared from polycaprolactone (PCL) or poly D,L-lactic acid (PDLLA) was sythesized and cultured with hBMSCs for 14 days with RNA extracted from cells on Day 1 and Day 14. Gene expression analysis was performed using BRB ArrayTools. GF = gas foam, SC = spun coat, BNF = big nanofiber, SNF = small nanofiber, FFF = free-form fabricated, TCPS = tissue culture polystyrene, TCPS+OS = tissue culture polystyrene with osteogenic supplements. The 72 arrays data was used previously in the publication: Kumar et al. The determination of stem cell fate by 3D scaffold structures through the control of cell shape, Biomaterials (2011) 32, 9188-9196. A companion data set of 24 arrays was submitted separately to GEO as GSE50744 and will be referenced to Baker et al.

Human Bone Marrow Stromal Cells cultured on 3D nanofiber scaffolds or 2D films

Project description:Microarray analysis was used to evaluate expression differences from a single donor human bone marrow stromal cells (hBMSCs) as a function of varied polymer-based tissue engineering scaffolds. These scaffolds include polycaprolactone (PCL) nanofibers (PCL_NF), films (PCL_SC), poly D,L-lactic acid (PDLLA) nanofibers (PDLLA_NF), films (PDLLA_SC), tissue culture polystyrene (TCPS) and TCPS with osteogenic supplements (TCPS_OS). The results revealed that scaffold structure was able to significantly affect gene expression, with nanofiber scaffolds inducing similar gene expression patterns to hBMCSs cultured with osteogenic media.

Craniofacial periosteum-derived cells as source for bone tissue engineering

Project description:The development of alternatives for autologous bone grafts is a major focus of bone tissue engineering. To produce living implants, the use of skeletal stem and progenitor cells (SSPCs) are envisioned as key ingredients. SSPCs can be obtained from bone marrow, adipogenic tissue, dental pulp and periosteum. Human periosteum-derived cells (hPDCs) exhibit a number of progenitor characteristics and have well-documented in vivo bone formation capacity. Here, we have characterized and compared hPDCs derived from tibia with new sources of hPDCs, i.e. from maxilla and mandible (craniofacial hPDCs, as a potential source for tissue engineered implants for craniofacial applications.

Engineering endochondral ossification using Sonic Hedgehog for bone regeneration

Project description:Endochondral ossification (EO) is the natural route for the regeneration of large and mechanically challenged bone defects. Regeneration occurs via a fibrocartilagenous phase which turns into bone upon vascularization and the formation of a transient collagen type X extra cellular matrix. These two critical initiator of EO are mediated by Hedgehog proteins. We investigated a tissue engineering approach using Sonic Hedgehog (Shh) as a pleiotropic factor regulating the in vitro formation of a vascularized bone tissue precursor for in vivo endochondral bone formation. The tissue engineered graft was formed using human mesenchymal stem cells and prevascularized using human umbilical vein endothelial cells. We show that Shh induced, in vitro, the maturation of the engineered vascular network along with the expression of collagen type X which resulted, in vivo, in an improved vascularization and the rapid formation of large amounts of osteoids through EO. Osteoids further matured into, currently unmatched, clinically relevant amount of lamellar bone including osteoclasts, bone lining cells and bone marrow-like cavities. This result suggests that Hh is a master regulator of EO allowing for the formation of complex tissues with considerable therapeutic potential for bone regeneration. The effect of Cyclopamine on expression of Hedgehog, angiogenesis and axon guidance marker genes was analyzed by seeding a coculture of 92% hMSCs and 8% huvEC supplemented or not in cyclopamine, for 12 days

Global MicroRNA Profiling in Human Bone Marrow Skeletal-Stromal or Mesenchymal-Stem Cells Identified Candidates for Bone Regeneration.

Project description:Bone remodeling and regeneration are highly regulated multistep processes involving posttranscriptional regulation by microRNAs (miRNAs). Here, we performed a global profiling of differentially expressed miRNAs in bone-marrow-derived skeletal cells (BMSCs; also known as stromal or mesenchymal stem cells) during in vitro osteoblast differentiation. We functionally validated the regulatory effects of several miRNAs on osteoblast differentiation and identified 15 miRNAs, most significantly miR-222 and miR-423, as regulators of osteoblastogenesis. In addition, we tested the possible targeting of miRNAs for enhancing bone tissue regeneration. Scaffolds functionalized with miRNA nano-carriers enhanced osteoblastogenesis in 3D culture and retained this ability at least 2 weeks after storage. Additionally, anti-miR-222 enhanced in vivo ectopic bone formation through targeting the cell-cycle inhibitor CDKN1B (cyclin-dependent kinase inhibitor 1B). A number of additional miRNAs exerted additive osteoinductive effects on BMSC differentiation, suggesting that pools of miRNAs delivered locally from an implanted scaffold can provide a promising approach for enhanced bone regeneration.
