• Sustained Growth Factor Delivery for Regenerating Tissues
  The Problem Millions of people worldwide suffer from traumatic injuries or health conditions that cause damage to soft tissues including nerves, muscles, and blood vessels. The body can heal some of that damage, but more serious cases like the severing of a nerve or sustained oxygen deprivation can lead to permanent loss of movement or...
• Bone Marrow-Like Scaffolds for Accelerating Immune Reconstitution
  An implantable bone marrow cryogel to accelerate the full reconstitution of the immune system, including T cell immunity, in patients that received chemotherapy and a bone marrow transplant. This could provide an off-the-shelf, material-based solution for patients with severe blood disorders whose immunity is recovering only slowly after treatment.
• Engineered Brain Organoids
  The ability to derive and manipulate pluripotent stem cells has opened up new avenues for modeling biological systems in both healthy and diseased conditions. In order to more fully recapitulate the tissue microenvironment with its cell-cell, cell-extracellular matrix, and cell-niche interactions, it is essential to transition stem-cell culturing from monolayers to 3D structures. Self-organization of...

  Printing Vascular Tissue
  Printing vessel vasculature is essential for sustaining functional living tissues. Until now, bioengineers have had difficulty building thick tissues, lacking a method to embed vascular networks. A 3D bioprinting method invented at the Wyss Institute and Harvard SEAS embeds a grid of vasculature into thick tissue laden with human stem cells and connective matrix. Printed...
