Welcome to the Niklason Lab!
Our laboratory seeks to utilize cells, in combination with what we know about their function, embryonic development, and physiological environments, to create functional tissues and organs that may one day help patients. This approach to Regenerative Medicine is firmly rooted in biology, yet makes ample use of engineering principles such as Design Criteria, biomechanical forces, biomimetic bioreactors, and the like.
For our work in vascular engineering, we are focusing on the differentiation of human iPS cells into vascular smooth muscle and endothelial phenotypes, novel bioreactor development, and chemical modifications of engineered vascular tissues to enhance their biocompatibility. We focus on both “large vessel” (i.e. arterial) and “small vessel” (i.e. capillary) engineering, using both small and large animals as testbeds.
For our work in lung cell therapy and whole lung regeneration, we utilize acellular lung scaffolds that are generated by the careful and quantitative decellularization of adult organs from a variety of species. These scaffolds are then repopulated with stem cell-derived and differentiated cells of various lineages. Design goals are the generation of patent microvasculature, differentiated epithelial lining, and appropriate tissue mechanics including surfactant-dependent compliance.
Lab Image Gallery
Airway Cast
Airway cast of a decellularized adult rat lung that is imaged by scanning electron microscopy. Preservation of alveolar airsac structures is evident.
3D
High resolution computed tomography 3-D reconstruction of rat left pulmonary artery, after decellularization. Preservation of multiple generations of vascular branching and hierarchy is evident.
Decellularized
Decellularized rat lung scaffold that is repopulated with both microvascular lung endothelial cells, and with neonatal rat mixed epithelium. Extensive repopulation of airways and vasculature is achievable.
First Implant
First implantation in the U.S. of an engineered artery in a patient, wherein the artery was engineered and then decellularized using technology developed in the Niklason laboratory.
