Deconvolution Software for Modern Fluorescence Microscopy

Description of Technology: This software invention pertains to Joint Richardson-Lucy (RL) deconvolution methods used to combine multiple images of an object into a single image for improving resolution in modern fluorescence microscopy. RL deconvolution merges images with very different point spread functions, such as in multi-view light-sheet microscopes, while preserving the best resolution information present in each image. RL deconvolution is also easily applied to merge high-resolution, high noise Start Printed Page 16349images with low-resolution, low noise images, relevant when complementing conventional microscopy with localization microscopy. The technique can be performed on images produced via different simulated illumination patterns, relevant to structured illumination microscopy (SIM) and image scanning microscopy (ISM) resulting in image qualities at least as good as standard inversion algorithms, but follows a simpler protocol that requires little mathematical insight. RL deconvolution can also be used to merge a series of several images with varying signal and resolution levels. This combination is relevant to gated stimulated-emission depletion (STED) microscopy and shows that high-quality image merges are possible even in cases where no explicit inversion algorithm is known.

Improved Methods To Measure Hyaluronan Acid

Description of Technology: The invention is directed to an improved method for measuring the amount of hyaluronan acid (HA) in a biological sample using an ELISA based system. HA is a disaccharide polymer that is expressed at elevated levels in patients afflicted with certain autoimmune diseases, including Graves' ophthalmopathy and rheumatoid arthritis. The amount and the length of HA present in a patient sample varies.

When compared to existing assays, the invention assay provides a more accurate and sensitive way to measure HA. Specifically, the first step in the invention assay involves determining the size range of the average molecular weight of HA in the sample. Next, the amount of HA in the sample is quantified using an ELISA system wherein HA binds to hyaluronan binding protein (HABP). Then, the binding results are compared against a control sample containing HA at an average molecular weight similar to that of HA in the sample being tested. Thus, the invention assay takes into account two variables that lead to significant errors in calculating the concentration of HA in a biological sample: (1) The wide range of HA particle sizes in a sample, and (2) differing binding efficiencies between HABP and HA at different particle sizes.

Potential Commercial Applications:

  • Diagnostic Test
  • Personalized Medicine

Competitive Advantages: More accurate and sensitive quantification of HA in biological samples when compared to commercially available ELISA kits.

Development Stage:

  • Early-stage
  • In vitro data available
  • Prototype

Human iPSC-Derived Mesodermal Precursor Cells and Differentiated Cells

Description of Technology: 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. Human iPSCs can be induced into any cell type and, since they can be maintained over many passages, they can serve as an almost unlimited source to generate cells from any given person. These properties make iPSC-derived cells a valuable product for cell therapies and toxicology or pharmaceutical high throughput screens. NIH investigators disclose an iPSC-derived mesodermal precursor cell line, positive for CD34 and CD31 expression, that may be used to produce at least four different cell types. When cultured under appropriate conditions, these mesodermal precursor cells can be used to produce hematopoietic stem cells, mesenchymal stem cells, smooth muscle cells, or unlimited functional endothelial cells.

Potential Commercial Applications:

  • The iPSC-derived mesodermal precursor cell (MPC) line described here can be used to produce hematopoietic stem cells, mesenchymal stem cells, smooth muscle cells, or unlimited functional endothelial cells.
  • The differentiated cells produced using the disclosed methods and MPC can be used for screening, as well as therapeutic applications.

Competitive Advantages: The mesodermal precursor cells have the ability to maintain their phenotype for extended periods without differentiating, when maintained under appropriate conditions.

Development Stage:

  • Early-stage
  • In vitro data available
  • In vivo data available (animal)

Silica Exposure Safety: Mini-Baghouse Systems and Methods for Controlling Particulate Release From Large Sand Transfer Equipment

Description of Technology: CDC scientists have developed an effective control for release of silica-containing dusts by using retrofitted mini baghouses for thief hatches on sand transfer trucks. Retrofit of the mini baghouses on sand transfer trucks will significantly reduce silica dust release and silica exposures in the workplace and surrounding community.

In the U.S., virtually every new oil and gas well is hydraulically fractured (HF) to stimulate well production. Each HF operation has 2-4 sand transfer trucks in use, and tens of thousands of pounds of sand are used for each stage of each multi-stage fracturing. Currently, there are no truck-mounted engineering controls for silica release at HF operations, posing an elevated risk of silica exposure to personnel and surrounding areas. CDC results have shown that silica workplace exposures at HF sites are completely uncontrolled at present (with the exception of personal respirator use), and silica exposures are likely to be the most significant and hazardous occupational chemical exposure on HF sites. Additionally, CDC field research has shown that personal breathing zone silica concentrations regularly exceed the maximum use concentration for both half-mask and full-face air purifying respirators. Use of this mini baghouse technology (multiple mini baghouse retrofits to sand trucks) will serve to limit release of silica dust, thereby diminishing silica exposure and increasing safety.

Potential Commercial Applications:

  • Controlling occupational exposure to silica, especially for work involving sand transfer trucks
  • Retrofitting currently operating heavy equipment
  • Gas and oil well-workers' well-being concern groups
  • Hydraulic fracturing operations situated near populated areas and associated insurers
  • Occupationally-mandated pneumoconiosis, and/or silicosis prevention programs for complying with safety regulations

Competitive Advantages:

  • Designed for retrofitting “thief hatches” of existing machinery
  • This technology will reduce silica exposure near hydraulic fracturing sites, helping to diminish one of the most hazardous exposure risks of such operations
  • Provides previously unavailable truck mounted engineering controls for silica release at hydraulic fracturing operations

Development Stage:

  • In situ data available (on-site)
  • Prototype

Dengue Vaccines: Tools for Redirecting the Immune Response for Safe, Efficacious Dengue Vaccination

Description of Technology: This CDC-developed invention relates to dengue vaccines that have been specifically developed for improved efficacy and directed immune response to avoid antibody-dependent enhancement (ADE) safety issues that, theoretically, may be associated with dengue vaccines and vaccinations. Dengue viral infection typically causes a debilitating but non-lethal illness in hosts. However, dengue hemorrhagic fever (DHF), the much more severe and life-threatening condition, is generally attributed to secondary dengue infections caused by a serotype different from the initial infection serotype by way of ADE. This effect, particularly notable in dengue viruses, should be given special consideration during vaccine design and construction.

This in vivo-validated technology provides a strategy and mechanism for increasing the safety of dengue vaccines and diminishing the likelihood of such Start Printed Page 16351vaccines inadvertently harming a recipient due to ADE-mediated effects. Any safe, effective dengue vaccine must produce well-balanced and tetravalent (for all four dengue serotypes) protective immunity. Despite decades of investigative effort there remains no effective, commercially available dengue vaccine and the greatest hurdle has been the difficulty of rapidly inducing this balanced immunity to all four dengue serotypes.

With this invention, CDC researchers have developed a cross-reactivity reduced dengue serotype 1 (DENV-1) DNA vaccine engineered to directly address ADE-related vaccine safety concerns. In vivo murine testing of wild-type and cross-reactivity-reduced vaccines demonstrated that this theoretical vaccine safety concern is real and that the cross-reactivity reduced DNA vaccine dramatically reduces dengue vaccination safety risk while increasing protective antibody responses. Properly developed and implemented, this novel vaccination strategy should help overcome this previously-unaddressed hindrance to dengue vaccine development.

Potential Commercial Applications:

  • Creation of a safe, efficacious and well-balanced dengue virus vaccine
  • Improving currently developed/developing dengue vaccines to mitigate potential antibody-dependent enhancement safety issues
  • Research tools for vaccine development programs for other flaviviruses, HIV

Competitive Advantages:

  • Murine in vivo studies indicating proof-of-principle, safety and efficacy
  • Addresses a long-standing “serotype immunity balancing” issue for dengue vaccine development
  • Presently there are no safe, effective commercially available dengue vaccines

Development Stage:

  • In vitro data available
  • In vivo data available (animal)
