This study reveals for the first time that MSC can alter the expression of several types of collagen and thus potentially modulate the extracellular matrix and stroma, which may at least partially explain the anti-cancer activity of MSC.
However, in the delayed phases after injury, MMPs and other proteases may also play beneficial roles by modulating the extracellular matrix (ECM) and trophic factors in the brain parenchyma and at the neurovascular interface [11], [17].
In principle a Na/HCO3 transporter could modulate the extracellular HCO3− concentration in response to horizontal cell polarization and mediate in that way negative feedback from horizontal cells to cones.
Second, vitamin D may prevent aggressive breast cancers by modulating the extracellular microenvironment, as vitamin D has been shown to alter the expression of a variety genes involved in extracelluar matrix remodeling [39], [40] and to modulate breast cancer phenotypes [41].
It is also proposed that the enzyme could modulate the extracellular matrix in the vessel wall affecting the downstream tissue-remodelling processes, associated with atherogenesis.
Extracellular proteolysis represents a potent and irreversible mechanism modulating the extracellular matrix and tissue remodeling, which can affect the breakdown of the BBB.
Two mechanisms to modulate the extracellular concentration of IGF1 were examined: cell-mediated depletion of ligand and extracellular sequestration by IGFBPs.
Malignant tumour cells have a critical role in modulating the extracellular environment and there is evidence that this is advantageous for tumour invasion and metastases.
Messenger RNA and protein levels of CYR61 and CTGF, both known to be capable of modulating the extracellular matrix, were increased in diabetic rats, whilst the AGE inhibitor aminoguanidine attenuated these effects of diabetes.
