Human iPSC-Derived Mesodermal Precursor Cells and Differentiated Cells

Cells, cell culture methods, and cell culture media compositions useful for producing and maintaining iPSC-derived cell lines that are of higher purity and maintain cell type integrity better than current iPSC-derived cell lines are disclosed. Human induced pluripotent stem cells (hiPSCs) can be generated by reprogramming somatic cells by the expression of four transcription factors. The hiPSCs exhibit similar properties to human embryonic stem cells, including the ability to self-renew and differentiate into all three embryonic germ layers: ectoderm, endoderm, or mesoderm.

Simple, Field-Usable Fluorescence-Based Isothermal LAMP Assay for the On-Site Diagnosis of Malaria

CDC researchers have developed improved Loop-Mediated Isothermal Amplification (LAMP) assays for the nucleic acid-based diagnosis of malaria in field settings. The approach employs Plasmodium genus-specific LAMP primers and a portable tube scanner to run the LAMP reaction and measure fluorescence signal (e.g., SYBR green) as a measure of DNA amplification in real time. Using this platform, the researchers were able to detect several different species of the human malaria parasites.

Local Positioning System for Position-Time-Condition Correlation, Data-logging and Analysis

This CDC-developed technology describes an automated system for monitoring worker hazard exposures by recording data about where and when hazards occur in a workplace or other environment. This allows the hazards to be avoided and harmful exposures and risks reduced. This field-tested technology consists of an integrated, hand-held electronics instrument and software system that will precisely correlate multiple exposure levels with position coordinates of the user and features real-time data acquisition.

MDCK-based Reporter System for Detection of Influenza Viruses, Antiviral Drug Screening, and Analysis of Neutralizing Antibodies

CDC researchers have developed a Madin-Darby Canine Kidney (MDCK) reporter cell line that is exceptionally permissive for influenza virus replication and provides a highly specific, sensitive approach for the simultaneous detection and isolation of influenza viruses. Simplified antibody neutralization assays and high-throughput antiviral drug screening can also be easily and efficiently implemented using this reporter system.

Improved Acoustic Plethysmograph System for Noninvasive Measurement of Pulmonary Function

CDC researchers have developed a novel acoustic whole body plethysmograph (AWBP) that allows measurement of tidal volume in lab animals, independent of gas compression in the lung. This system provides particular advantages over the traditional whole body plethysmograph (WBP) when measuring model animals with increased gas compression due to increased airway resistance or increased acceleration in the breathing pattern.

Focused Electrostatic Collection of Aerosol Particles for Chemical Analysis by Spectroscopic Techniques

This CDC-developed technology is an aerosol preconcentration unit (APU) designed for use with spectroscopic detection techniques, including emission, Raman, or infrared spectroscopies. Most existing pulsed microplasma techniques, such as laser-induced breakdown, for aerosols rely mainly on filter-based collection and suffer from poor accuracy, precision, and detection limits and require long sample collection times.

AMA1-RON2 Complex-Based Vaccine Against Malaria

This technology relates to a malaria vaccine composed of a protein complex of Apical Membrane Antigen (AMA1) and rhoptry neck protein 2 (RON2) with an adjuvant. AMA1 is a crucial component of the Plasmodium invasion machinery and is a leading candidate for antimalarial vaccine development. AMA1-based vaccines have shown ability to block red cell invasion in in vitro assays, but protection has so far not translated to in vivo human infections.

Novel Epstein-Barr Virus Vaccines

Epstein-Barr Virus (EBV) is the causative agent of infectious mononucleosis and is associated with certain types of cancers, such as Hodgkin's lymphoma, Burkitt's lymphoma, gastric carcinoma, and nasopharyngeal carcinoma. There are currently no vaccines against EBV on the market and there is only supportive treatment available for EBV infection.
