Functionally Characterized Human PBMCs: An Improved In Vitro Model of Human Immune Response

Alexei Miagkov, Ph.D., Senior Scientist, Immunology, ATCC
Recorded June 30, 2016

Abstract: Human Peripheral Blood Mononuclear Cells (PBMCs) contain many of the functional cell types of immune system, and are an ideal model to study the human immune response in vitro. Currently, PBMCs are being used in basic and clinical research areas including basic immunology and cell biology, infectious diseases, vaccine development, tumor immunology, and drug discovery. PBMC are also widely used for monitoring disease progression, designing personalized approaches to treatment, and predicting the occurrence of treatment-associated adverse events. The majority of PBMC applications rely on highly complex cell-based assays; however, phenotypic and functional variability of human PBMCs makes the development and validation of these assays difficult. Additionally, variations in cell collection and cryopreservation protocols can further affect PBMC properties. In this presentation, we demonstrate that pre-screening characterization of lot-specific functional activity of PBMCs is extremely useful for selecting cells to address individual experimental goals.

Key Points:

  • PBMCs play a critical role in modern biomedical research; however, the functional activity of these cells is highly variable
  • Many factors affecting PBMC variability, including genetic diversity and environmental pressure, are outside of researchers’ control
  • Conducting pre-screening and establishing PBMC functional activity profiles offers an attractive solution to address PBMC variability

Solving Identity Crisis in Animal Cells; Best Practices with DNA Barcodes and STR Analysis

Speakers: Yvonne Reid, Ph.D., Manager, Scientist, ATCC
Jason Cooper, M.S., Adjunct Professor, Community College of Allegheny County
Recorded March 31, 2016

Abstract: Animal cell lines are important in vitro systems and tools for scientists in diverse disciplines such as basic cell biology, genetic mapping, gene expression, and gene therapy. Animal cell line identity, which is a crucial first step in cell line authentication, is frequently underappreciated and ignored by most research scientists. Over the years numerous cell lines have been shown to be misidentified due, in part, to poor techniques and inadequate authentication protocols. It is estimated that the financial loss incurred by misidentified cell lines is in the millions of dollars. Animal cell line identity now requires a comprehensive strategy that employs several complementary technologies. Technological advances have given rise to improved capabilities. An overview of these technologies to include STR analysis for human cell line identity and CO1 for animal cell line identity will be presented.

Key Points:

  • Cell line authentication is critical to meet funding, quality control, and publication requirements
  • Short tandem repeat (STR) profiling is an accepted form of authentication that differentiates human cell lines
  • DNA barcoding complements STR profiling by providing species-specific identification

Barry R. Bochner, Ph.D., CEO & CSO, Biolog, Inc.
Recorded October 29, 2015 

Phenotype MicroArray (PM) technology allows a biologist to test thousands of phenotypes of a cell line in a single experiment to gain a comprehensive overview of the metabolism, physiology, and pathway fluxes. It provides phenomic and metabolomic information that is complementary to genomic or proteomic analysis and often more easy to interpret and more useful. The PM technology platform is applicable to a wide range of cells including bacterial, fungal, or animal and enables metabolic analysis in the context of genotype-phenotype studies. For example, it can be used for (1) analyzing cells with mutations to determine the metabolic and physiologic effects of genetic differences, (2) studying and defining cell metabolism and metabolic regulation, (3) understanding the interplay of environment and hormonal signals on cell metabolism and physiology, (4) optimizing cell culture conditions in bioprocess development and optimization, and (5) examining and maintaining the stability of cell lines. Specific examples and discoveries will be presented to illustrate the many uses of this cell phenotyping technology. Download Presentation (.pdf) View Recording.

Yvonne ReidSTR Profiling for Human Cell Line Authentication

Yvonne A. Reid, Ph.D., Manager/Scientist, Cell Biology
ATCC
Recorded September 10, 2015

Over the past few decades, much has been written about the misidentification of cell lines, primarily human cell lines. It is not unusual that studies of the ‘same’ cell lines performed by different laboratories often show different results using the same methodology. Thus far, numerous cell lines are known to be misidentified due, in part, to a lack of adequate testing. The financial loss incurred by using misidentified cell lines is estimated in the millions of dollars. Cell line authentication is crucial; however, the scientific community seems indifferent about the consequences or wanting to take steps in preventing it. The validity of scientific data demands that consistent and unequivocal verification of cell line identity is precise. To alleviate these concerns, the implementation of best tissue culture practices to include routine authentication of human cell lines by STR profiling is highly recommended by funding agencies, journal editors, and scientific societies.

Recorded September 11, 2014

Influenza remains one of the most significant infectious diseases worldwide, causing acute respiratory tract illnesses and accounting for 25% of infections that exacerbate chronic lung infections. To date, several epidemics and four major influenza pandemics have been recorded. Influenza viruses have caused an estimated 3 million cases of serious illness and around 500,000 deaths annually worldwide. Influenza infections are primarily and effectively controlled by vaccines that elicit protective immunity. Influenza viruses undergo rapid antigenic shift and drift that results in the emergence of new strains each year. Therefore, influenza vaccines need to be reformulated every year to match the circulating strains. In this webinar, we will provide an overview of the influenza virus and will explore the current treatment strategies for influenza infections. We will also highlight viral strains and associated materials offered by ATCC that can be used in influenza research or in the development and validation of novel preventative and therapeutic techniques.
