Aging Adipose‐Derived Mesenchymal Stem Cells, Cultured on a Native Young Extracellular Matrix, Are Protected From Senescence and Apoptosis Along With Increased Expression of HLA‐DR and CD74 Associated With PI3K Signaling

open access: yesAging Cell, Volume 24, Issue 9, September 2025.
The maintenance of aging mesenchymal stem cells (MSCs) on extracellular matrix synthesized by human amniotic fluid‐derived pluripotent stem cells (ECM Plus), a young microenvironment, remarkably restored their quantity and quality along with up‐regulating HLA‐DR and CD74.

A biomechanical role for perlecan in the pericellular matrix of articular cartilage [PDF]

open access: yesMatrix Biology, 2012
Chondrocytes are surrounded by a narrow pericellular matrix (PCM) that is biochemically, structurally, and biomechanically distinct from the bulk extracellular matrix (ECM) of articular cartilage. While the PCM is often defined by the presence of type VI collagen, other macromolecules such as perlecan, a heparan sulfate (HS) proteoglycan, are also ...

Role of collagens and perlecan in microvascular stability: exploring the mechanism of capillary vessel damage by snake venom metalloproteinases. [PDF]

open access: yesPLoS ONE, 2011
Hemorrhage is a clinically important manifestation of viperid snakebite envenomings, and is induced by snake venom metalloproteinases (SVMPs). Hemorrhagic and non-hemorrhagic SVMPs hydrolyze some basement membrane (BM) and associated extracellular matrix

Variations in the Peritrophic Matrix Composition of Heparan Sulphate from the Tsetse Fly, Glossina morsitans morsitans [PDF]

open access: yes, 2018
Tsetse flies are the principal insect vectors of African trypanosomes—sleeping sickness in humans and Nagana in cattle. One of the tsetse fly species, Glossina morsitans morsitans, is host to the parasite, Trypanosoma brucei, a major cause of African ...

A Structural Bridge Between Kingdoms: How Collagen‐Derived Peptides Influence Plant Stress and Growth Pathways

open access: yesPhysiologia Plantarum, Volume 177, Issue 5, September/October 2025.
ABSTRACT Collagen‐derived protein hydrolysates (CDPH) are widely used as plant biostimulants primarily due to their content of bioactive oligopeptides. When applied to hydroponically grown Solanum lycopersicum plants, CDPH significantly promoted root development, particularly by increasing the number and length of lateral roots.

Perlecan Maintains the Integrity of Cartilage and Some Basement Membranes [PDF]

open access: yesThe Journal of Cell Biology, 1999
Perlecan is a heparan sulfate proteoglycan that is expressed in all basement membranes (BMs), in cartilage, and several other mesenchymal tissues during development. Perlecan binds growth factors and interacts with various extracellular matrix proteins and cell adhesion molecules. Homozygous mice with a null mutation in the perlecan gene exhibit normal

Investigating the Expression and Function of CCN2 in Articular Cartilage

open access: yes, 2009
The pericellular matrix (PCM) is a distinct zone of matrix that surrounds individual chondrocytes throughout articular cartilage. Although not much is known about its function, our group has shown that it has a role in mechanotransduction by controlling ...

Perlecan and synaptophysin changes in denervated skeletal muscle.

open access: yesNeural regeneration research, 2012
The present study observed sciatic nerve and gastrocnemius muscle changes in denervated rats using morphology methods, and assessed expression of perlecan, an extracellular matrix component, which is located at the skeletal muscle cell surface as acetylcholine esterase, as well as synaptophysin, a synaptic marker.

Cytoneme-mediated signaling essential for tumorigenesis. [PDF]

open access: yes, 2019
Communication between neoplastic cells and cells of their microenvironment is critical to cancer progression. To investigate the role of cytoneme-mediated signaling as a mechanism for distributing growth factor signaling proteins between tumor and tumor ...

Genetic and Environmental Contributions to Serological Biomarkers of Extracellular Matrix Remodeling in Asthma: A Twin Study

open access: yesClinical and Translational Allergy, Volume 15, Issue 8, August 2025.
ABSTRACT Background Asthma is characterized by airway obstruction driven by chronic inflammation, leading to extracellular matrix (ECM) remodeling. This involves ECM alterations, including increased collagen deposition and elastolysis, resulting in airway wall thickening and irreversible airflow limitation. Despite ECM remodeling's known role in asthma,
