Paraben esters and their salts are widely used as preservatives in cosmetics, personal care products, pharmaceuticals, and foods. We previously reported that parabens promoted adipocyte differentiation in vitro and increased adiposity but suppressed serum marker of bone formation in vivo. Here, we investigated the effects of parabens (methylparaben and butylparaben) on modulating cell fate of multipotent stem cell line C3H10T1/2. Both parabens modulated adipogenic, osteogenic, and chondrogenic differentiation of C3H10T1/2 cells in vitro...

Recent identification and isolation of suture stem cells capable of long term self-renewal, clonal expanding and differentiating demonstrate their essential role in calvarial bone development, homeostasis and injury repair. These bona fide stem cells express high level of Axin2 and are able to mediate bone regeneration and repair in a cell autonomous fashion. The importance of Axin2 is further demonstrated by its genetic inactivation in mice causing skeletal deformities resembling craniosynostosis in humans...

Growth factors such as transforming growth factor beta1 (TGF-β1), have critical roles in the regulation of the chondrogenic differentiation of mesenchymal stem cells (MSCs), which promote cartilage repair. However, the clinical applications of the traditional growth factors are limited by their high cost, functional heterogeneity and unpredictable effects, such as cyst formation. It may be advantageous for cartilage regeneration to identify a low-cost substitute with greater chondral specificity and easy accessibility...

Cartilage engineering remains a challenge due to the difficulties in creating an in vitro functional implant similar to the native tissue. An approach recently explored for the development of autologous replacements involves the differentiation of stem cells into chondrocytes. To initiate this chondrogenesis, a degree of compaction of the stem cells is required; hence, we demonstrated the feasibility of magnetically condensing cells, both within thick scaffolds and scaffold-free, using miniaturized magnetic field sources as cell attractors...

BACKGROUND: Cartilage tissue engineering is a growing field due to the lack of regenerative capacity of native tissue. The use of bioreactors for cartilage tissue engineering is common, but the results are controversial. Some studies suggest that microgravity bioreactors are ideal for chondrogenesis, while others show that mimicking hydrostatic pressure is crucial for cartilage formation. A parallel study comparing the effects of loading and unloading on chondrogenesis has not been performed...

Vascular calcification resulting from hyperphosphatemia is a major determinant of mortality in chronic kidney disease (CKD). Vascular calcification is driven by aldosterone-sensitive osteogenic transformation of vascular smooth muscle cells (VSMCs). We show that even in absence of exogenous aldosterone, silencing and pharmacological inhibition (spironolactone, eplerenone) of the mineralocorticoid receptor (MR) ameliorated phosphate-induced osteo-/chondrogenic transformation of primary human aortic smooth muscle cells (HAoSMCs)...

Aging is the most prominent risk factor triggering several degenerative diseases, such as Osteoarthritis (OA). Due to its poor self-healing capacity, once injured cartilage needs to be re-established. This process mighmight be approached bythrough resorting to cell-based therapies and/or tissue engineering. Human mesenchymal stem cells (hMSC) represent a promising approach due to their chondrogenic differentiation potential. Presently, in vitro chondrogenic differentiation of MSCs is limited by two main reasons: Aging aging of MSCs, which determines the loss of cell proliferative and differentiationed capacity and MSC-derived chondrocyte hypertrophic differentiation, which limits the use of these cells in cartilage tissue regeneration approach...

BACKGROUND: Mesenchymal stem cells derived from the synovial membrane (synovial MSCs) are a candidate cell source for regenerative medicine of cartilage and menisci due to their high chondrogenic ability. Regenerative medicine can be expected for RA patients with the inflammation well-controlled as well as OA patients and transplantation of synovial MSCs would also be a possible therapeutic treatment. Some properties of synovial MSCs vary dependent on the diseases patients have, and whether or not the pathological condition of RA affects the chondrogenesis of synovial MSCs remains controversial...

Inorganic phosphate (Pi) has been recognized as an important signaling molecule that modulates chondrocyte maturation and cartilage mineralization. However, conclusive experimental evidence for its involvement in early chondrogenesis is still lacking. Here, using high-density monolayer (2D) and pellet (3D) culture models of chondrogenic ATDC5 cells, we demonstrate that the cell response to Pi does not correlate with the Pi concentration in the culture medium but is better predicted by the availability of Pi on a per cell basis (Pi abundance)...

Worldwide, the most recognized musculoskeletal degenerative disease is osteoarthritis (OA). Sesamin, a major abundant lignan compound present in Sesamun Indicum Linn, has been described for its various pharmacological effects and health benefits. However, the promoting effects of sesamin on chondrogenic differentiation have not yet been observed. Herein, the aim of this study was to investigate the effects of sesamin on cell cytotoxicity and the potent supporting effects on chondrogenic differentiation of human amniotic fluid-derived mesenchymal stem cells (hAF-MSCs)...

The extracellular signal-regulated protein kinase 1/2 (Erk1/2) and p38 mitogen‑activated protein‑kinase pathways serve important roles in the regulation of osteogenic and chondrogenic differentiation in mesenchymal stem cells (MSCs). However, the exact mechanism remains unclear, and the effect is controversial. In the present study, the effects of Erk1/2 and p38 on the osteogenic and chondrogenic differentiation of dental pulp stem cells (DPSCs) were compared in vitro. The results indicated that inhibition of Erk1/2 is able to enhance the osteogenic differentiation of DPSCs and inhibit chondrogenic differentiation, whereas inhibition of p38 demonstrated the opposite effect...

Cartilage is an avascular, aneural, and alymphatic connective tissue with a limited capacity caused by low mitotic activity of its resident cells, chondrocytes. Natural repair of full thickness cartilage defects usually leads to the formation of fibrocartilage with lower function and mechanical force compared with the original hyaline cartilage and further deterioration can occur. Tissue engineering and regenerative medicine is a promising strategy to repair bone and articular cartilage defects and rehabilitate joint functions by focusing on the optimal combination of cells, material scaffolds, and signaling molecules...

Cartilage tissue engineering is emerging as a therapeutic approach for the repair and regeneration of cartilage tissue defects resulting from trauma and disease. It is still essential to explore approaches that employ combinations of ideal seed cells, biomaterials, and growth factors to repair defect areas because cartilage lacks spontaneous regenerative capabilities and traditional treatments do not fully satisfy clinical requirements. The purpose of this review is to summarize key advances in this area with an emphasis on adult stem cells because these cells possess a self-renewal ability and the potential for multi-directional differentiation when cultured under appropriate conditions, such as chondrocyte differentiation to synthesize cartilage-specific matrix proteins...

Orchestration of bone repair processes requires crosstalk between different cell populations, including immune cells and mesenchymal stem/stromal cells (MSC). Extracellular vesicles (EV) as mediators of these interactions remain vastly unexplored. Here, we aimed to determine the mechanism of MSC recruitment by Dendritic Cells (DC), hypothesising that it would be mediated by EV. Primary human DC-secreted EV (DC-EV), isolated by ultracentrifugation, were characterized for their size, morphology and protein markers, indicating an enrichment in exosomes...

Nanostructured materials have drawn a broad attention for their applications in biomedical fields. Ligand-modified nanomaterials can well mimic the dynamic extracellular matrix (ECM) microenvironments to regulate cell functions and fates. Herein, ECM mimetic gold nanoparticles (Au NPs) with tunable surface arginine-glycine-aspartate (RGD) density are designed and synthesized to induce the chondrogenic differentiation of human mesenchymal stem cells (hMSCs). The biomimetic Au NPs with an average size of 40 nm shows good biocompatibility without affecting the cell proliferation in the studied concentration range...

Tissue engineering using adult mesenchymal stem cells (MSCs), a promising approach for cartilage repair, is highly dependent on the nature of the matrix scaffold. Thermoresponsive, photocrosslinkable hydrogels were fabricated by functionalizing pepsin-soluble decellularized tendon and cartilage extracellular matrices (ECM) with methacrylate groups. Methacrylated gelatin hydrogels served as controls. When seeded with human bone marrow mesenchymal stem cells (MSCs) and cultured in chondrogenic medium, methacrylated ECM hydrogels experienced less cell-mediated contraction, as compared against non-methacrylated ECM hydrogels...

Cartilage tissue engineering is making progress but the competing available strategies still leave room for improvement and consensual overviews regarding the best combinations of scaffolds and cell sources are limited by the capacity to compare them directly. In addition, because most strategies involve autologous cell transfer, once these will be optimized, the resulting implants require individual quality control prior to grafting in order to emphasize patient-to-patient differential responsiveness to engineering processes...

With the aim to increase type II collagen content in the scaffold-free cartilage-like cell sheet using human bone marrow mesenchymal stem cells, we examined the effect of epigallocatechin-3-gallate (EGCG) addition to the chondrogenic medium for the cell sheet culture. The addition of EGCG (10 μM) increased the content of type II collagen 2-fold, while the addition did not markedly change the expression level of the genes encoding type II collagen and Sox 9. The reactive oxygen species level in the cells in cell sheets was thought to be too low to suppress the accumulation of type II collagen...

Tissue engineered constructs (TECs) based on spheroids of bone marrow mesenchymal stromal cells (BM-MSCs) combined with calcium phosphate (CaP) micro-particles and enveloped in a platelet-rich-plasma (PRP) hydrogel showed that aggregation of MSCs improves their ectopic bone formation potential. The stromal vascular fraction (SVF) and adipose-derived MSCs (ASCs) have been recognized as interesting MSC source for bone tissue engineering but their ectopic bone formation is limited. We investigated whether aggregation of ASCs could similarly improve ectopic bone formation by ASCs and SVF cells...

BACKGROUND: Microcarrier cultures which are useful for producing large cell numbers can act as scaffolds to create stem cell-laden microcarrier constructs for cartilage tissue engineering. However, the critical attributes required to achieve efficient chondrogenic differentiation for such constructs are unknown. Therefore, this study aims to elucidate these parameters and determine whether cell attachment to microcarriers throughout differentiation improves chondrogenic outcomes across multiple microcarrier types...
