Nitric Oxide-Releasing Polymers for Wound Healing

 A number of factors can play a detrimental role in the process of wound healing such as poor nutritional status, smoking, various drugs, cancer, and diabetes.  Wound healing impairment is a challenging clinical problem with no efficacious treatments currently available.  Nitric oxide (NO) has been shown to play a role in the process of wound healing by promoting both the proliferative and remodeling phases of healing. 

Generation of Artificial Mutation Controls for Diagnostic Testing

This technology relates to a method of generating artificial compositions that can be used as positive controls in a genetic testing assay, such as a diagnostic assay for a particular genetic disease. Such controls can be used to confirm the presence or absence of a particular genetic mutation. The lack of easily accessible, validated mutant controls has proven to be a major obstacle to the advancement of clinical molecular genetic testing, validation, quality control (QC), quality assurance (QA), and required proficiency testing.

Method of Producing Immortalized Primary Human Keratinocytes for HPV Investigation, Testing of Therapeutics, and Skin Graft Generation

One of the major limitations of using cultured keratinocytes for research studies is that primary keratinocytes senesce after a few passages. Keratinocytes from specific anatomical sites are also difficult to culture. Scientists at the NIH have demonstrated that primary keratinocytes, from several anatomical sites, when treated with a small-molecule inhibitor of the ROCK protein maintain a proliferative state and become immortal without genetic modification to the cells.

Next-Generation 5-HT-2B Serotonin-Receptor Antagonists for Anti-Fibrotic & Cardiopulmonary Therapy

This technology includes a family of small-molecule antagonists that selectively block the 5-HT2B serotonin receptor—an upstream driver of tissue-remodeling—to address fibrotic, cardiopulmonary and related disorders. Built on a conformationally-locked “(N)-methanocarba” nucleoside scaffold, the compounds show nanomolar potency, >30–400-fold selectivity over the closely related 5-HT2C receptor, and favorable oral bioavailability in rodents.

Selective A3 Adenosine Receptor Agonists for the Treatment of Chronic Neuropathic Pain and Other Conditions

This technology includes the creation and use of A3 adenosine receptor (A3AR)-selective agonists for treating chemotherapy-induced peripheral neuropathy, chronic neuropathic pain, rheumatoid arthritis, psoriasis, and other conditions. A3 receptors for adenosine are found in most cells and endogenous activation of the A3 receptors can result in apoptosis, thereby relieving the inflammation or targeting a tumor. A3AR agonists have been a promising strategy for the treatment of various diseases.

Polymer-Cast Inserts for Cell Histology and Microscopy

Three-dimensional (3D) cell cultures systems are important for studying cell biology because they provide in vivo-like microenvironments more physiologically relevant than two-dimensional (2D) culture systems. In 3D culture systems, cells are grown in culture matrixes and turn into spheroids and organoids later processed for downstream analysis by microscopy and histology techniques. The processing of 3D cultures for analysis by microscopy or histology is laborious and time-consuming due to incompatibility of the 3D culture vessels and the microscopy and pathology blocks.

DeePlexing – Extending Imaging Multiplexity Using Machine Learning

Spatial proteomics and transcriptomics are fast-emerging fields with the potential to revolutionize various branches of biology. In the last five years, various multiplex immunofluorescence and immunohistochemistry imaging methods have been developed to stain 5-60 different protein markers in a given tissue. Nonetheless, most of these techniques are iterative and can image a maximum of 3-8 markers in a single cycle, resulting in processing time of several hours to days.

Machine Learning and/or Neural Networks to Validate Stem Cells and Their Derivatives for Use in Cell Therapy, Drug Delivery, and Diagnostics

Many biological and clinical procedures require functional validation of a desired cell type. Current techniques to validate rely on various assays and methods, such as staining with dyes, antibodies, and nucleic acid probes, to assess stem cell health, death, proliferation, and functionality. These techniques potentially destroy stem cells and risk contaminating cells and cultures by exposing them to the environment; they are low-throughput and difficult to scale-up.
