RNA-Seq analysis used to explore the bone-froming mechanism of microbially catalyzed biomaterials

ABSTRACT: We developed a microbial catalytic concept and strategy to prepare calcium carbonate with micro/nanostructures on the surface of bioceramics to improve bone-forming bioactivity. It involves three processes: bacterial adhesion on biomaterials, production of carbonate assisted with bacteria, nucleation and growth of calcium carbonate nano-crystals on the surface of bioceramics. The microbially catalyzed biominerals exhibited relatively uniform micro/nanostructures on both 2D and 3D CaSiO3 bioceramics. The descriptive analysis of RNA-sequencing revealed that the topographic and chemical cues presented by microbially catalyzed micro/nanostructures could stimulate the biological processes including adhesion, proliferation and differentiation. The study offers a microbially catalytic concept and strategy of fabricating micro/nanostructured biomaterials for tissue regeneration.

Meta-omics analysis of microbially induced carbonate precipitation at a CO2 rich geyser in Utah

Project description:Microbially induced carbonate precipitation (MICP) refers to the biogeochemical process in which calcium carbonate is precipitated by altering the local geochemical environment (Mortensen et al. 2011). These alterations occur as a by-product of common microbial metabolic activities by increasing the local carbonate content as well as pH thereby saturating the solution in respect to carbonate. To better understand the microbial ecology of MICP on a community level in natural environments, we chose to evaluate microbial communities derived from travertine adjacent to Crystal Geyser (CG), Utah. CG is a cold-driven, CO2 rich geyser which is surrounded by colorful travertine that has been suggested to be generated through microbial processes. We used a cultivation-independent, multi-omics approach combined with geochemical measurements to investigate metabolic pathways and physiologies potentially involved in MICP at CG. We collected samples from the top 20 cm of travertine adjacent to Crystal Geyser, Utah in November 2019 and June 2021 (38.9384° N, 110.1354° W) wearing gloves at all times. We sampled 1 m away from the borehole (CG-1) and 10 m away from the borehole (CG-10). We preserved all collected samples in RNAlater-like solution (Menke et al., 2017, Front. Microbiol. 8) in a 1:10 sediment: RNAlater-like solution ratio as previously validated (Jensen et al. (2021, Micro. Spec. 2021, 9:2)

Differential gene expression of RNA extracted from A549 cell line cultured with Amorphous Calcium Carboante (ACC) or without

Project description:Amorphous calcium carbonate (ACC) is a non-crystalline form of calcium carbonate, which is composed of aggregated nano-size primary particles. Here, we wanted to evaluate how ACC affects gene expression in a human lung cancer cell line (A549).

Cholecalciferol and Calcium Carbonate in Treating Patients With Colon Cancer That Has Been Removed by Surgery

Project description:RATIONALE: The use of cholecalciferol and calcium carbonate may keep colon cancer from coming back in patients with colon cancer that has been removed by surgery. PURPOSE: This randomized clinical trial is studying two different doses of cholecalciferol to compare how well they work when given together with calcium carbonate in treating patients with colon cancer that has been removed by surgery.

Surface topography enhances differentiation of mesenchymal stem cells towards osteogenic and adipogenic lineages

Project description:Surface topography impacts on cell growth and differentiation, but it is not trivial to generate defined surface structures and to assess the relevance of specific topographic parameters. In this study, we have systematically compared in vitro differentiation of mesenchymal stem cells (MSCs) on a variety of groove/ridge structures. Micro- and nano-patterns were generated in polyimide using reactive ion etching or multi beam laser interference, respectively. These structures affected cell spreading and orientation of human MSCs, which was also reflected in focal adhesions morphology and size. Time-lapse demonstrated directed migration parallel to the nano-patterns. Overall, surface patterns clearly enhanced differentiation of MSCs towards specific lineages: 15 um ridges increased adipogenic differentiation whereas 2 um ridges enhanced osteogenic differentiation. Notably, nano-patterns with a periodicity of 650 nm increased differentiation towards both osteogenic and adipogenic lineages. However, in absence of differentiation media surface structures did neither induce differentiation, nor lineage-specific gene expression changes. Furthermore, nanostructures did not affect the YAP/TAZ complex, which is activated by substrate stiffness. Our results provide further insight into how structuring of tailored biomaterials and implant interfaces - e.g. by multi beam laser interference in sub-micrometer scale - do not induce differentiation of MSCs per se, but support their directed differentiation.
