These data suggest that treatment with EC-seeded aligned nanofibrillar scaffolds improved blood perfusion and arteriogenesis, when compared to treatment with cells alone or scaffold alone, and have important implications in the design of therapeutic cell delivery strategies.
Together, these findings suggest that MPsShh+ are able to improve blood perfusion and this effect is directly mediated by Shh signalling, as illustrated by impaired blood flow recovery in the presence of Shh pathway inhibitor.
We herein demonstrate that LE− lesions exhibit an accelerated vascularization and improved blood perfusion compared with LE+ lesions.
Systemic administration of chemotherapy together with hyaluronidase (PEGPH20), which degrades HA, improved blood vessel perfusion and resulted in increased sensitivity and improved survival in pancreatic cancer mouse models [ 62, 63].
Wound healing is accelerated by removing excess interstitial fluid, improving blood flow reducing bacterial count, stimulating angiogenesis and increasing tissue perfusion.
Finally, we demonstrated that a partial recovery of vascular performance is possible following re-endothelialization confirmed by fewere-endothelialization confirmedproved byood clearance fewerwing wholextravasationsinn.
In a severe murine hindlimb ischemia model, HGF delivery from the affinity-binding system improved tissue blood perfusion and induced mature blood vessel network formation.
Transplantation of hypoxic HUVEC/cbMSC aggregates into a mouse model of an ischemic limb significantly promoted formation of functional vessels, improved regional blood perfusion, and attenuated muscle atrophy and bone losses, thereby rescuing tissue degeneration.
27– 30 Recently, Batchelor et al provided clinical proof of concept that improved tumor blood perfusion, as a consequence of vascular normalization, was related to longer overall survival (OS) in newly diagnosed GBM patients treated with a combination of anti-angiogenic therapy (Cediranib) (Recentin™; AstraZeneca plc, London, UK) and standard treatment.
26 Evidence from several preclinical studies has confirmed that the temporary vascular normalization as a result of anti-angiogenic therapy, improves tumor blood perfusion, which consequently increases the delivery of chemotherapy and oxygen, and this potentially enhances the efficacy of both chemotherapy and RT.
Moreover, no human data show that substantial (>20 mL/kg) fluid resuscitation reliably improves blood pressure or end-organ perfusion (an elusive outcome given that organ blood flow cannot be accurately measured in septic humans).
