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.

A peptide hydrogel for use in vascular anastomosis

In collaboration with surgery specialists from Johns Hopkins University, researchers at the National Cancer Institute (NCI) developed novel hydrogel compositions and methods of using them in the microsurgical suturing of blood vessels, which is particularly beneficial for surgeons in whole tissue transplant procedures. The lead candidate electropositive hydrogels, called APC1, was demonstrated in anastomosis mice models to be well tolerated, biocompatible, and non-toxic.

Photoactivatable Lipid-based Nanoparticles as a Vehicle for Dual Agent Delivery

The invention relates to novel lipid-based nanoparticles (liposomes) for use in targeted, on demand and on site drug delivery. The particles include a wall surrounding a cavity, wherein the wall is comprised of:

  1. A lipid bilayer comprising 1,2-bis(tricosa-10,12-diynoyl)-sn-glycero-3-phosphocholine (DC8,9PC), dipalmitoylphosphatidylcholine (DPPC), and 1,2-distearoyl-sn-glycero-3-

phosphoethanolamine-N-[methoxy(polyethylene glycol)-2000] (DSPE-PEG2000), and

Devices for Improved Tissue Cryopreservation and Recovery

Problem: Cryopreservation is a process where living biological materials like cells, tissues, and cell therapies (which are susceptible to damage caused by unregulated chemical kinetics) are preserved by cooling to very low temperatures in the presence of specific cryopreservation media that protects the biological material from damage. In order to be used, the biological material ideally should be thawed in a controlled manner that minimizes damage and desirably brings the material back to a viable state.

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.
