Key Figures

Protease-Responsive Scaffolds era

Anthony Atala [1], affiliated with Harvard University [3] and the Forest Institute [4], was a leading figure in the Protease-Responsive Scaffolds era. His key contribution in this era centers on tissue-engineered autologous bladder constructs, as reported in the 2006 paper Tissue-engineered autologous bladders for patients needing cystoplasty [6], which illustrated how scaffold-guided, autologous regeneration could address cystoplasty needs. James J. Yoo [2], affiliated with Harvard University [3] and the University of California, San Francisco [5], contributed to advancing autologous regenerative strategies within this era. His key contribution lies in the tissue-engineered autologous bladder work that demonstrates the feasibility of autologous, scaffold-guided regeneration and supports moves toward clinical-scale translation of protease-responsive matrices, as highlighted by the 2006 paper Tissue-engineered autologous bladders for patients needing cystoplasty [6].

Multimaterial Biofabrication era

Adam W. Feinberg [1], affiliated with Harvard University [3] and the University of Pittsburgh [4] during the Multimaterial Biofabrication era, advanced regenerative engineering. In 2015 his work 'Three-dimensional printing of complex biological structures by freeform reversible embedding of suspended hydrogels' [6] introduced the Freeform Reversible Embedding of Suspended Hydrogels (FRESH) approach, enabling multimaterial 3D printing of soft biomaterials and complex microarchitectures that bridge microscale cues to macroscale constructs. Jennifer A. Lewis [2], affiliated with Harvard University [3] and Johns Hopkins University [5], contributed to multimaterial biofabrication through the 2016 paper 'Three-dimensional bioprinting of thick vascularized tissues' [7]. This work advanced the creation of perfusable, vascularized centimeter-scale tissues, aligning with the era's goals of spatially patterned growth, vascular networks, and material-driven stem cell fate.

In Situ Injectable Scaffolds era

Seeram Ramakrishna [1], affiliated with Cornell University [3] and Nanyang Technological University [4], is a prominent figure in regenerative engineering. During this era, his key contributions center on advancing electrospinning for tissue engineering, as illustrated by Electrospinning for tissue engineering applications [7], which demonstrates how electrospun scaffolds can mimic ECM architecture and enable scalable scaffold fabrication. Masoud Mozafari [2], affiliated with University of Toronto [5] and University of Birmingham [6] in this era, is a leading figure in regenerative engineering. His contributions, highlighted by Electrospinning for tissue engineering applications [7], emphasize the versatility of electrospinning in fabricating tissue-engineering scaffolds and enabling ECM-mimetic designs for injectable, in situ regenerative platforms.
