Tissue Engineered Heart Valves

Despite recent advances in tissue engineered heart valves (TEHV), one of the major challenges is finding a suitable cell source for seeding TEHV scaffolds. Native heart valves are durable because valve interstitial cells (VICs) maintain tissue homeostasis by synthesizing and remodeling the extracellular matrix. In this study, we demonstrate that induced pluripotent stem cells (iPSCs) can be derived into induced mesenchymal stem cells (iMSCs) using our feeder-free protocol and then further differentiated into VICs using a 3D cell culture environment. The differentiation efficiency was quantified using flow cytometry, immunohistochemistry staining, RT-PCR, and trilineage differentiation. In addition, iMSCs were encapsulated in polyethylene (glycol) diacrylate (PEGDA) hydrogels of varying stiffness, grafted with adhesion peptide (RGDS), to promote cell proliferation, remodeling, and further differentiation into VIC-like cells. VICs phenotype was characterized by the expression of αSMA, vimentin, F-actin, and the ECM production after 7, 14, and 21 days. The results demonstrated that using our feeder-free differentiation protocol, iMSCs were differentiated from iPSCs. Our iMSCs had a 99.9% and 99.4% positive expression for MSC markers CD90 and CD44, respectively. As expected, there was 0.019% expression of CD45, which is a hematopoietic marker. In addition, iMSCs differentiated into adipogenic, chondrogenic, and osteogenic. When MSC derived cells were encapsulated in PEGDA hydrogels that mimic the leaflet modulus, we observed expression of αSMA and F-actin after 7 days. Thus, the results from this study suggest that iPSCs can be a suitable cell source for TEHV by using a feeder-free differentiation approach and 3D culture.

Abstract Directed differentiation of induced pluripotent stem cells (iPSCs) towards specific lineages remains a major challenge in regenerative medicine, while there is a growing perception that this process can be influenced by the three-dimensional environment. In this study, we investigated whether iPSCs can differentiate towards mesenchymal stromal cells (MSCs) when embedded into fibrin hydrogels to enable a one-step differentiation procedure within a scaffold. Differentiation of iPSCs on tissue culture plastic or on top of fibrin hydrogels resulted in a typical MSC-like phenotype. In contrast, iPSCs embedded into fibrin gel gave rise to much smaller cells with heterogeneous growth patterns, absence of fibronectin, faint expression of CD73 and CD105, and reduced differentiation potential towards osteogenic and adipogenic lineage. Transcriptomic analysis demonstrated that characteristic genes for MSCs and extracellular matrix were upregulated on flat substrates, whereas genes of neural development were upregulated in 3D culture. Furthermore, the 3D culture had major effects on DNA methylation profiles, particularly within genes for neuronal and cardiovascular development, while there was no evidence for epigenetic maturation towards MSCs. Taken together, iPSCs could be differentiated towards MSCs on tissue culture plastic or on a flat fibrin hydrogel. In contrast, the differentiation process was heterogeneous and not directed towards MSCs when iPSCs were embedded into the hydrogel.

: Liver disease (hepatic disease) adversely affects the normal function of the liver and causes liver problems. Druginduced liver injury (DILI) can be predicted by primary human hepatocytes. However, the sources of hepatocytes for largescale drug toxicity screening are limited. To solve this problem, pluripotent stem cells (PSCs), mesenchymal stem cells (MSCs), and hepatic stem cells (HSCs) have emerged as attractive cell sources for cell-based therapies. Human PSCs including embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) have the ability to undergo self-renewal and to differentiate into lineages of ectoderm, mesoderm, and endoderm. Human PSC can be used for generation of hepatocytes to facilitate the development of novel drugs for treatment of severe liver diseases. The therapeutic potential of PSC-derived hepatocytes for liver failure have been identified to enhance the development of chemically defined and xenogenic-free 3D culture methods. To date, several hepatic differentiation strategies and various extracellular matrix (ECM) components have been employed to produce hepatocytes or hepatic-like cells (HLCs) in vitro. In this review, we focused on the potential of Matrigel, collagen type 1, RoGel, and laminin as ECM on the differentiation and function of hESC- and hiPSC-derived hepatocytes. The hepatic differentiation of human ESCs and iPSCs would offer an ideal tool for cell therapy and liver diseases.
