Publication number: 20240075189Abstract: A two-component biomaterial and method that replicates both the structural complexity and diverse molecular composition necessary to create a tissue's form and function. It is an objective of the current invention to use the unique combination material and methods herein to provide a pharmaceutical composition, a medical device, a tissue regeneration scaffold, as well as a scaffold for 3D organ culture (tissue on a chip, lab grown meat, research stem cell differentiation) comprising a significant amount of acellular tissue particles packed tightly and held together via crosslinking between the acellular particles and a thiolated protein.Type: ApplicationFiled: December 14, 2021Publication date: March 7, 2024Applicant: The Regents of the University of Colorado, a body corporateInventors: Jeanne Barthold, Corey P.

Patent number: 11360010Abstract: A low-cost, magnetically-driven device that enables visualization and quantification of dynamic changes in cell behavior during mechanical stretch. Using this device, it was observed that nuclei of mouse embryonic skin fibroblasts underwent rapid but divergent responses to strain magnitude, showing nuclear area increase and chromatin decompaction during 5% (low) strain, but nuclear area decrease and chromatin condensation during 20% (high) strain. Only responses to low strain were dependent on calcium, while actin inhibition abrogated any nuclear response and increased stretch-induced DNA damage. Stretch-activation revealed a shift in actin filaments away from (low strain) or towards (high strain) the nuclear periphery. The findings suggest that different pathways control strain level-dependent cell behavior and that mechanical confinement of nuclei through actin may be a protective mechanism during high strain loads.Type: GrantFiled: July 20, 2020Date of Patent: June 14, 2022Assignee: The Regents of the University of Colorado, a body corporateInventors: Corey P.

Patent number: 11129543Abstract: A process for more sensitive characterization of tissue composition for generating a quantitative MRI (qMRI) map and corresponding delta analysis. Intervertebral disc degeneration (IVDD), resulting in the depletion of hydrophilic glycosaminoglycans (GAGs) located in the nucleus pulposus (NP), can lead to debilitating neck and back pain. Magnetic Resonance Imaging (MRI) is a promising means of IVD assessment due to the correlation between GAG content and MRI relaxation values. T1 and T2 relaxation data were obtained from healthy cervical IVDs, and relaxation data was modeled using both conventional and stretched exponential (SE) decays. Normalized histograms of the resultant quantitative MRI (qMRI) maps were fit with stable distributions. SE models fit relaxation behavior with lower error compared to monoexponential models, indicating anomalous relaxation behavior in healthy IVDs. SE model parameters T1 and T1 increased with IVD segment, while conventional monoexponential measures did not vary.Type: GrantFiled: July 8, 2019Date of Patent: September 28, 2021Assignee: The Regents of the University of ColoradoInventors: Corey P. Neu, Robert L. Wilson, David Reiter
