Abstract Fri021: Local Controlled Release of an Optimized Angiogenic Growth Factor Cocktail Improves Regeneration in Ischemic Injury

Q: What is the clinical evidence from this study?

Population: Ischemic injury. Intervention: VIP-loaded biomaterial (VEGF, IGF-1, and PDGF) vs. Blank biomaterial and no treatment controls. Primary outcome: Perfused vascular density at 1 week (6-fold increase).

Key result

VIP-loaded biomaterial boosts perfused vascular density ~6-fold vs blank scaffold in ischemic injury.

6-fold increase

Why the study?

Does local delivery of a VEGF, IGF-1, and PDGF cocktail improve vascularization and regeneration in a rat model of ischemic injury?

Key Points

The VIP-loaded biomaterial increased perfused vascular density by 6-fold compared to the blank control at one week.
Using a rat model of ischemic wound healing, enhanced vascularization improved both the rate and magnitude of wound closure.
An iterative design approach identified top angiogenic factors, VEGF, IGF-1, and PDGF, for optimal controlled release.
This research highlights the potential of proangiogenic therapies to drive regeneration in compromised microcirculatory networks.

Structured PICO

Does local delivery of a VEGF, IGF-1, and PDGF cocktail improve vascularization and regeneration in a rat model of ischemic injury?

Population

Wild-type immune competent rats evaluated in a subcutaneous gel plug assay and a model of ischemic wound healing over 2 weeks.

Intervention

Local delivery of a protein cocktail containing VEGF, IGF-1, and PDGF (VIP) via a type 1 collagen and heparin-modified alginate biomaterial

Comparator

Blank biomaterial and no treatment controls

Outcome

Vascular size, density, morphology, rate and magnitude of wound closure, and skin regenerationsurrogate

Main Result

Effect estimate: 6-fold increase

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

A locally delivered combination of VEGF, IGF-1, and PDGF from an optimized biomaterial significantly enhances rapid vascularization and wound healing in a rat model of ischemic injury.

Roser et al. (2025) studied Ischemic injury. VIP-loaded biomaterial (VEGF, IGF-1, and PDGF) vs. Blank biomaterial and no treatment controls was evaluated on Perfused vascular density at 1 week (6-fold increase). A VIP-loaded biomaterial delivering VEGF, IGF-1, and PDGF increased perfused vascular density by 6-fold versus blank biomaterial at 1 week in a rat model of ischemic injury.
