Sandwich-like Microenvironments to Harness Cell/Material Interactions

1Center for Biomaterials and Tissue Engineering, Universitat Politècnica de València, 2Division of Biomedical Engineering, School of Engineering, University of Glasgow, 3Biomedical Research Networking Center in Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN)


JoVE 53090

The following protocol describes the procedure to assemble sandwich-like cultures to be used as an intermediate stage between bi-dimensional (2D) and three-dimensional (3D) cellular environments. The engineered systems can have applications in microscopy, biomechanics, biochemistry and cell biology assays.

A Novel Culture Model for Human Pluripotent Stem Cell Propagation on Gelatin in Placenta-conditioned Media

1Department of Biomedical Science, Graduate School of Medicine, Korea University


JoVE 53204

This protocol provides a simple and efficient way to propagate human pluripotent stem cells (hPSCs) using only conditioned media derived from the human placenta in a gelatin-coated dish without additional exogenous supplementation or hPSC-specific synthetic substrata.

Kidney Regeneration in Adult Zebrafish by Gentamicin Induced Injury

1Nephrology Division, Department of Medicine, Massachusetts General Hospital, 2Basic Sciences Division, Fred Hutchinson Cancer Research Center, 3Department of Genetics, Harvard Medical School


JoVE 51912

Here we present a reliable method to study adult kidney regeneration by inducing acute kidney injury by gentamicin injection. We show that injury is dependent on gentamicin dosage and environmental temperature using in situ hybridization to label lhx1a+ developing new nephrons.

Probing High-density Functional Protein Microarrays to Detect Protein-protein Interactions

1Department of Genetics, Stanford University, 2Stanford Center for Genomics and Personalized Medicine, Stanford University


JoVE 51872

Using protein microarrays containing nearly the entire S. cerevisiae proteome is probed for rapid unbiased interrogation of thousands of protein-protein interactions in parallel. This method can be utilized for protein-small molecule, posttranslational modification, and other assays in high-throughput.

HPLC Measurement of the DNA Oxidation Biomarker, 8-oxo-7,8-dihydro-2’-deoxyguanosine, in Cultured Cells and Animal Tissues

1Environmental Health Science and Research Bureau, Health Canada


JoVE 52697

The goal of this protocol is the detection of the DNA oxidation marker, 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxo-dGuo) by HPLC-ED, in DNA from cultured cells or animal tissues.

Adapting the Electrospinning Process to Provide Three Unique Environments for a Tri-layered In Vitro Model of the Airway Wall

1Division of Drug Delivery and Tissue Engineering, University of Nottingham, 2Laboratory of Biophysics and Surface Analysis, School of Pharmacy, University of Nottingham, 3Division of Immunology and Allergy, School of Molecular Medical Sciences, University of Nottingham, 4Division of Respiratory Medicine, School of Clinical Sciences, University of Nottingham, 5NIHR Respiratory Biomedical Research Unit, University of Leicester, 6School of Sport, Exercise, and Health Sciences, Loughborough University


JoVE 52986

Advancements in biomaterial technologies enable the development of three-dimensional multi-cell-type constructs. We have developed electrospinning protocols to produce three individual scaffolds to culture the main structural cells of the airway to provide a 3D in vitro model of the airway bronchiole wall.

Gene Transfection toward Spheroid Cells on Micropatterned Culture Plates for Genetically-modified Cell Transplantation

1Graduate School of Medicine, Laboratory of Clinical Biotechnology, The University of Tokyo, 2Graduate School of Engineering, Department of Materials Engineering, The University of Tokyo, 3Graduate School of Engineering, Department of Bioengineering, The University of Tokyo


JoVE 52384

This protocol describes a cell transplantation system using genetically modified, injectable spheroids. Cell spheroids are cultured on micropatterned culture plates and recovered after gene introduction using polyplex nanomicelles. This system facilitates prolonged transgene expression from the transplanted cells in host animals while maintaining the innate function of the cells.

Microbead Implantation in the Zebrafish Embryo

1Department of Biological Sciences, University of Notre Dame


JoVE 52943

The zebrafish is an excellent model system for genetic and developmental studies. Bead implantation is a valuable tissue manipulation technique that can be used to interrogate developmental mechanisms by introducing alterations in local cellular environments. This protocol describes how to perform microbead implantation in the zebrafish embryo.
