Second harmonic generation light quantifies the ratio of type III to total (I + III) collagen in a bundle of collagen fiber

Scientific Reports, 2021
The ratio of type III to type I collagen is important for properly maintaining functions of organs and cells. We propose a method to quantify the ratio of type III to total (type I + III) collagen (λ III ) in a given collagen fiber bundle using second ...

Region- and layer-specific investigations of the human menisci using SHG imaging and biaxial testing

Frontiers in Bioengineering and Biotechnology, 2023
In this paper, we examine the region- and layer-specific collagen fiber morphology via second harmonic generation (SHG) in combination with planar biaxial tension testing to suggest a structure-based constitutive model for the human meniscal tissue. Five

Fibrillar Collagen Quantification With Curvelet Transform Based Computational Methods

Frontiers in Bioengineering and Biotechnology, 2020
Quantification of fibrillar collagen organization has given new insight into the possible role of collagen topology in many diseases and has also identified candidate image-based bio-markers in breast cancer and pancreatic cancer. We have been developing

Microcrimped Collagen Fiber‐Elastin Composites [PDF]

Advanced Materials, 2010
Emerging biomaterials based upon analogues of native extracellular matrix proteins provide an opportunity to create protein scaffolds that mimic tissue mechanical behavior and guide cellular responses. However, in order to reproduce macroscale tissue properties, protein analogues must be endowed with appropriate microstructural features. In particular,

A three-dimensional computational model of collagen network mechanics. [PDF]

PLoS ONE, 2014
Extracellular matrix (ECM) strongly influences cellular behaviors, including cell proliferation, adhesion, and particularly migration. In cancer, the rigidity of the stromal collagen environment is thought to control tumor aggressiveness, and collagen ...

Unique Collagen Fibers for Biomedical Applications [PDF]

Marine Drugs, 2018
The challenge to develop grafts for tissue regeneration lies in the need to obtain a scaffold that will promote cell growth in order to form new tissue at a trauma-damaged site. Scaffolds also need to provide compatible mechanical properties that will support the new tissue and facilitate the desired physiological activity.

Mammary collagen architecture and its association with mammographic density and lesion severity among women undergoing image-guided breast biopsy

Breast Cancer Research, 2021
Background Elevated mammographic breast density is a strong breast cancer risk factor with poorly understood etiology. Increased deposition of collagen, one of the main fibrous proteins present in breast stroma, has been associated with increased ...

Three-dimensional remodeling of collagen fibers within cervical tissues in pregnancy

Journal of Innovative Optical Health Sciences, 2023
The cervix is a collagen-rich connective tissue that must remain closed during pregnancy while undergoing progressive remodeling in preparation for delivery, which begins before the onset of the preterm labor process.

Alveolar Bone Microstructure Surrounding Orthodontic Anchor Screws with Plasma Surface Treatment in Rats

Journal of Functional Biomaterials, 2023
A lateral load was applied to anchor screws that had undergone surface treatment, and the structure, cellular dynamics, and quality of the bone surrounding anchor screws were analyzed to investigate the effect of this surface treatment on the peri ...
