American Journal of Physiology Paper of the Year Award


Recently, at Experimental Biology 2015 being held in Boston, MA. Jennifer Durham received honors for ‘Pericyte contractility controls endothelial cell cycle progression and sprouting: Insights into angiogenic switch mechanics’, which we published late last year. The work, which teaches how pericyte chemo-mechanics controls endothelial growth dynamics and angiogenic switching, not only represents a major padadigm-shift in our understanding the regulatory role that pericytes play in orchestrating microvascular morphogenesis; but, the work will enable our creating ‘next generation’ cellular therapies capable of modulating pathological or physiological angiogenesis. Congratulations to my outstanding colleagues: Jennifer Durham, Howard Surks, Brian Dulmovits. This is truly a great achievement, demonstrating the global attention our work is receiving while offering considerable new hope for all those in need of healing.

Center Director delivers Henry Stewart Talk, entitled ‘Dynamic Reciprocity and Wound Healing’

Professor Herman recently delivered a Henry Stewart Talk (HST) on dynamic reciprocity and wound healing.  A link to the HST can be found here:

Insights into Angiogenic Switch Mechanics: A Role for Microvascular Pericytes in Wound Healing

Recent work ongoing in the Center for Innovations in Wound Healing Research now indicates that microvascular pericytes can ‘instruct’ capillary-derived endothelial cells, ‘switching’ the endothelium from a growth-arrested into a growth-promoted state.  With this shift, there is a marked increase in angiogenic potential when specific features of the pericyte are altered via genetic and molecular means. With this manipulation, pericytes are mechanically altered in that the cells become more contractile and better able to activate angiogenesis in response to injury.  These exciting findings have recently published in the American J Physiology-Cell Physiology.

Center Director Interview – Wound Healing Peptides and Therapeutic Innovation

Recently, Ira Herman was interviewed about the therapeutic potential of the wound healing peptides created at Tufts University’s Center for Innovations in Wound Healing Research.  Here is the YouTube link to the interview with Professor Herman

Pericytes are protective for retinal microvessels

In a recent study, work ongoing in TIWR in collaboration with colleagues at the University of Virginia indicates that a vascular progenitor cell population derived from adipose is capable of protecting the retinal capillaries against the damaging effects of elevated oxygen. These pre-clinical findings lend strong support for the notion that pericyte-like cells derived from adipose may offer an innovative cell-based therapy for patients suffering with diabetic retinopathy or age-related macular degeneration.

The work was recently published in PLoS ONE

TIWR Director to present at the Alliance for Regenerative Medicine

 ‘Clinical Outlooks for Regenerative Medicine’, which was held in Boston, MA on June 19, 2012, was a remarkable event.. bringing industry and academic leaders together for an exciting program.

From the Alliance for Regenerative Medicine Meeting Website:

“As many regenerative medicine and cell therapy products move into clinical trials, a clearer understanding of how these products will be administered and how they will perform clinically is critical for achieving regulatory approval and ultimately, for commercialization. This meeting will bring together leading regenerative medicine companies with clinicians and investigators from major research establishments where clinical trials are being conducted, with a goal to enhance the understanding of the key issues facing these products as they approach the marketplace”


Bioactive Wound Healing Peptides Promote Wound Healing In Vivo

Recent work from the Tufts Center for Innovations in Wound Healing Research has revealed that two novel peptides combine to synergistically accelerate wound healing using an in vivo model of impaired healing.  This work was recently published in PLoS One ( ) and was recently covered globally ( )

Speeding Up The Healing Process

Work ongoing at the Center for Innovations in Wound Healing Research was recently highlighted in Technology Review

The Dynamics of Wound Healing

Recent work reveals that wound healing dynamics are tightly and reciprocally regulated. In particular, cellular components within the epidermal and dermal wound microenvironments transduce signals that control extracellular matrix remodeling and wound healing dynamics. In turn, these cellular and extracellular signaling cascades control whether or to what extent wound repair progresses or is chronically impaired. In this recent report, we consider these key aspects of dynamic reciprocity.

Bioactive Peptides Promote Wound Healing

Newly-created bioactive peptides promote wound healing through the growth of new blood vessels and epithelial tissue, such as skin. These wound-healing peptides, synthesized by researchers at the Tufts Center for Innovations in Wound Healing Research promote re-epithelialization and wound healing angiogenesis as reported online in Wound Repair and Regeneration
