Escalating cases of organ shortage and donor scarcity worldwide are alarming reminders of the need for alternatives to allograft tissues. Within the last three decades, research efforts in the field of regenerative medicine and tissue engineering continue to address the unmet need for artificial tissues and organs for transplant. Work in the field has evolved to create what we consider a new field, Regenerative Engineering, defined as the Convergence of advanced materials science, stem cell science, physics, developmental biology and clinical translation towards the regeneration of complex tissues and organ systems. Included in the regenerative engineering paradigm is advanced manufacturing. Three-dimensional (3D) bioprinting is a promising and innovative biofabrication strategy to precisely position biologics, including living cells and extracellular matrix (ECM) components, in the prescribed 3D hierarchal …
