Reproducibility in Research

Scope of the crisis

Concern over the rigor and reproducibility of biomedical research has raised concerns in recent years across academic and industry laboratories, biomedical journals, and government funding agencies. Numerous cases have been reported in which initial, promising results with a candidate drug could not be repeated in other labs.

The CellAssist brings new capabilities for reproducible cell, tissue, and suspension culture

Cell, tissue, and suspension culture has remained a largely manual process with inadequate tools for improving quantification and documentation. Fortunately, the CellAssist instrument provides many of the capabilities needed to improve rigor and reproducibility of cell, tissue and suspension culture and cell-based assays.

Title:

Comparative Analysis of Co-Cultured Amniotic Cell-Conditioned Media with Cell-Free Amniotic Fluid Reveals Differential Effects on Epithelial-Mesenchymal Transition and Myofibroblast Activation

Authors:

Sam Fagg, et al

Published:

biomedicines by MDPI

Quote:

“Myofibroblast activation is a cellular response elicited by a variety of physiological or pathological insults whereby cells initiate a coordinated response intended to eradicate the insult and then revert back to a basal state. However, an underlying theme in various disease states is persistent myofibroblast activation that fails to resolve.”

“Biomedical research needs upgraded standards for the monitoring, control and reporting of the environmental conditions of cells in culture.”

Good Science Needs Good Cells: Thrive Bioscience

Authors:

Thomas Forest Farb-Horch

Published:

Silicon Review, August 2020

Quote:

“As a result of customers having the CellAssist, when an experiment does not work as planned, a researcher can now review all of their cells and processes and understand why. This is key to good science. Because good science needs good cells.”

Title:

The costs of using unauthenticated, over-passaged cell lines: How much more data do we need?

Authors:

Peyton Hughes, Damian Marshall, Yvonne Reid, Helen Parkes & Cohava Gelber

Published:

BioTechniques, November 2007

Quote:

“Based on submissions to major cell repositories in the last decade, it is estimated that between 18% and 36% of cell lines may be contaminated or misidentified.”

Fixing problems with cell lines

Authors:

Published:

Science, December 19th, 2014

Quote:

“Despite the important role of cell, tissue and suspension culture in the study of biology and medicine, evidence has accumulated that cell lines are frequently misidentified or contaminated by other cells or microorganisms.”

“Analyses of a variety of tissue culture collections and cells sent to repositories for curation and storage from labs in the United States, Europe, and Asia suggest that at least 15% of cell lines are misidentified or contaminated (4, 5).”

Title:

The Economics of Reproducibility in Preclinical Research

Authors:

Jon R. Lorsch, Francis S. Collins, Jennifer Lippincott-Schwartz

Published:

PLOS Biology, June 5, 2015

Quote:

“The history of cell lines used in biomedical research is riddled with misidentification and cross-contamination events [29], which have been estimated to range from 15% to 36% [30].”

“Lifesaving therapies are being delayed, research budgets face increasing pressure, and drug development and treatment costs are rising. Improving reproducibility remains a critical cornerstone to solving each of these challenges.”

In cancer science, many “discoveries” don’t hold up

Authors:

Sharon Begley

Reuters, March 28, 2012

Quote:

“The reproduction of results is the cornerstone of science; yet, at times, reproducing the results of others can be a difficult challenge…. Despite using seemingly identical methods, reagents, and specimens, our two laboratories quite reproducibly were unable to replicate each other’s… cell [profiles]…. A set of data that was supposed to be completed in a few months took 2 years to understand and sort out”

Imaging in Developmental Biology: An Essential Tool with No Instructions

Authors:

Guillermo Marques, Thomas Pengo, and Mark A. Sanders

Published:

Journal of Biomolecular Techniques, December 2019

Quote:

“Imaging is a fundamental tool in biomedical disciplines… In our work at a major imaging core, we are often met with the situation in which the experiments our clients want to recreate are poorly described, making analysis and replication of the published literature difficult.”
