Droplet microfluidics is combined with bio-orthogonal thiol–ene click chemistry to fabricate micrometer-sized, monodisperse fibrinogen-containing hyaluronic acid hydrogel microbeads in a mild, radical-free procedure in the presence of human mesenchymal stem cells (hMSCs). The gel beads serve as microniches for the 3D culture of single hMSCs, containing hyaluronic acid and additional fibrinogen for cell surface binding, and they are porous and stable in tissue culture medium for up to 4 weeks with mechanical properties right in the range of soft solid tissues (0.9–9.2 kPa). The encapsulation procedure results in 70% viable hMSCs in the microbeads after 24 hours of culture and a very high degree of viability of the cells after long term culture of 2 weeks. hMSCs embedded in the microniches display an overall rounded morphology, consistent with those previously observed in 3D culture. Upon induction, the multipotency and differentiation potential of the hMSCs are characterized by staining of corresponding biomarkers, demonstrating a clear heterogeneity in the cell population. These hydrogel microbeads represent a versatile microstructured material platform with great potential for studying the differences of material cues and soluble factors in stem cell differentiation in a 3D tissue-like environment at the single cell level.

Biomaterials Science

Biomaterials Science is an international high impact journal exploring the science of biomaterials and their translation towards clinical use. Its scope encompasses new concepts in biomaterials design, studies into the interaction of biomaterials with the body, and the use of materials to answer fundamental biological questions. Papers do not necessarily need to report a new biomaterial but should provide novel insight into the biological applications of the biomaterial. Articles that primarily focus on demonstrating novel materials chemistry and bring a molecular picture to bear on a given material’s suitability as a biomaterial are more suited to our companion journal, Journal of Materials Chemistry B. Biomaterials Science publishes primary research and review-type articles in the following areas: molecular design of biomaterials, including translation of emerging chemistries to biomaterials science of cells and materials at the nanoscale and microscale materials as model systems for stem cell and human biology materials for tissue engineering and regenerative medicine (Nano)materials and (nano)systems for therapeutic delivery interactions at the biointerface biologically inspired and biomimetic materials, including bio-inspired self-assembly systems and cell-inspired synthetic tools next-generation biomaterials tools and methods
