Special Issue Information

Dear Colleagues,

The induced pluripotent stem cell (iPSCs) is a promising patient-specific cell source for tissue engineering. To overcome the limitations associated with stability, efficiency, and in vivo adaptability of traditional iPSC culture protocols, biomaterials can play critical roles in the iPSC field not only via the integration of biomaterials with existing iPSC in vitro expansion and differentiation culture strategies, but also by facilitating efficient iPSC transplantation. So far, with multidisciplinary efforts from stem cell biologists, materials scientists, and engineers, developing well-defined biomaterial substrates has unfolded the possibility of modulating the epigenetic state of iPSCs through nanoscale topographical cues, mechanical dynamics, and novel targeting gene delivery technologies.

In this Special Issue, we welcome articles with a strong focus on biomaterial-based in vitro and/or in vivo activation of iPSC for expansion and differentiation applicable in regenerative medicine. We will also be pleased to include the review articles concerning the state of the art and novel concepts in biomaterials for next-generation iPSC transplantation strategies. The Special Issue will cover a wide spectrum of research subjects including:

  • Novel biomaterial designs optimal for large-scale in vitro iPSC expansion and differentiation;
  • Nanotopographic modifications of scaffolds and mechanism of iPSC response to surface cues;
  • Intracellular delivery kinetics in reprogramming factor-loaded biomaterials;
  • Extracellular matrix patterning for epigenetic regulation of iPSCs;
  • Electrical/mechanical stimuli-based iPSC modulation;
  • 3D bioprinting consisting of iPSC and biomaterials.

The production and transplantation of functionally active human neurons is a promising approach to cell therapy. Biocompatible and biodegradable matrices that effectively promote the growth and directed differentiation of neural precursor cells (NPCs) into the desired neuronal types are very important. The aim of this study was to evaluate the suitability of novel composite coatings (CCs) containing recombinant spidroins (RSs) rS1/9 and rS2/12 in combination with recombinant fused proteins (FP) carrying bioactive motifs (BAP) of the extracellular matrix (ECM) proteins for the growth of NPCs derived from human induced pluripotent stem cells (iPSC) and their differentiation into neurons. NPCs were produced by the directed differentiation of human iPSCs. The growth and differentiation of NPCs cultured on different CC variants were compared with a Matrigel (MG) coating using qPCR analysis, immunocytochemical staining, and ELISA. An investigation revealed that the use of CCs consisting of a mixture of two RSs and FPs with different peptide motifs of ECMs increased the efficiency of obtaining neurons differentiated from iPSCs compared to Matrigel. CC consisting of two RSs and FPs with Arg–Gly–Asp–Ser (RGDS) and heparin binding peptide (HBP) is the most effective for the support of NPCs and their neuronal differentiation. Full article
