Polyvinyl alcohol/gelatin hydrogels regulate cell adhesion and chromatin accessibility

Project description:Cell adhesion is known to heavily influence cell migration and wound healing. A number of cell adhesion molecules and their roles has been extensively studied. However, the changes of global chromatin accessibility and gene expressions correlated with cell adhesion is still unclear. Here we prepared a series of PVA/Gelatin hydrogels to handily regulate cell adhesion by adjusting gelatin concentration and found that cell adhesion area and the ratio of non-circular cells were increased with the increasement of gelatin concentration while cell circularity was decreased. Our results showed that widespread chromatin accessibility was increased with increasing expression level of histone deacetylase 11 (Hdc11) under poor cell adhesion. Meanwhile, one branch of MAPK pathway - ERK 1/2 which involved in mechanotransduction signaling was also found in the enrichment analysis of downregulated genes. This work provided a handy method to regulate cell adhesion and these findings deepen our understanding of the cell adhesion process and its associated chromatin accessibility.

Culturing C2C12 myotubes on micromolded gelatin hydrogels accelerates myotube maturation

Project description:We report that differentiation of the C2C12 myoblast line on patterened hydrogels results in the increased expression of muscle sarcomere genes and more closely models expression changes that happen in in vivo muscle differentiation than do C2C12 myoblasts cultured on unpatterened substrates.

Single cell analysis of iPSC-derived cortical organoids in biofunctionalized gelatin hydrogels

Project description:Human neural organoid models have become an important tool for studying neurobiology. In this work, we compared Matrigel to an N-cadherin peptide-functionalized gelatin methacryloyl hydrogel (termed GelMA-Cad) for culturing cortical neural organoids. Specifically, we compare five materials: (1) Matrigel, (2) GelMA-Cad with high crosslinker (HC), (3) GelMA-Cad with low crosslinker (LC), (4) GelMA HC and (5) GelMA LC. We determined that both mechanical properties and peptide presentation can tune cell fate and diversity in gelatin-based matrices during differentiation. Of particular note, cortical organoids cultured in GelMA-Cad produce higher numbers of neurogenic and ciliated radial glia and upper-layer excitatory neurons—an important population for modeling neurodegenerative disease—compared to GelMA and Matrigel controls.

Polyvinyl alcohol expanded mouse HSC cultures (scRNA-Seq)

Project description:We previously reported a polyvinyl alcohol-based mouse hematopoietic stem cell (HSC) culture protocol that efficiently expanded transplantable HSCs for at least a month ex vivo (Wilkinson et al., Nature 2019). Here, we investigated the molecular consequences of oxygen concentration on 28-day ex vivo HSC cultures using single cell RNA-seq
