Promotion of Spinal Cord Repair
Customer Says:Biogelx hydrogel is easy to prepare following the company’s protocols. Most importantly, the stiffness of the hydrogel can be tuned to be compatible to that of the central nervous system (CNS) tissue – this is very important for any biomaterial…
Stem Cell Differentiation
Customer Says:“The ability to generate hydrogels over a range of stiffnesses from a single material was a huge advantage for our metabolomics experiments as it allowed us to control stem cell growth and differentiation without the use of different media formulations,…
Improving Cartilage Phenotype from Differentiated Pericytes
Customer Says:“Having a biomaterial system that is able to influence phenotypic expression is hugely desirable as a replacement for chemically-induced differentiation methods, as being able to match the features of tissue produced in vitro to the required structure of the lost…

Controlling cancer cell fate using localized biocatalytic self-assembly of an aromatic carbohydrate amphiphile
This paper describes a simple carbohydrate amphiphile able to self-assemble into nanofibers upon enzymatic dephosphorylation. The self-assembly can be triggered by alkaline phosphatase (ALP) in solution or in situ by the ALP produced by osteosarcoma cell line, SaOs2. In the latter case, assembly and localized gelation occurs mainly on the cell surface. The gelation of the pericellular environment induces a reduction of the SaOs2 metabolic activity at an initial stage (≤7 h) that results in cell death at longer exposure periods (≥24 h). We show that this effect depends on the phosphatase concentration and thus, it is cell-selective with prechondrocytes ATDC5 (that express ~15-20 times lower ALP activity compared to SaOs2) not being affected at concentrations ≤ 1 mM. These results demonstrate that simple carbohydrate derivatives can be used in an anti-osteosarcoma strategy with limited impact on the surrounding healthy cells/tissues.
Probing the Metabolomics of Stem Cell Differentiation with Biomaterials
In this issue of Chem, Ulijn, Dalby, and co-workers have developed a novel peptide-based hydrogel platform as a screening tool for identifying metabolites that can bias differentiation of mesenchymal stem cells.
Stem Cell Fate Is a Touchy Subject
Uncoupling synergistic interactions between physio-chemical cues that guide stem cell fate may improve efforts to direct their differentiation in culture. Using supramolecular hydrogels, Alakpa et al. (2016) demonstrate that mesenchymal stem cell differentiation is paired to depletion of bioactive metabolites, which can be utilized to chemically induce osteoblast and chondrocyte fate.
