Research

Dr. Xie's research interfaces between stem cell biology and nanotechnology to try and understand stem cell fate decisions and develop stem cell-based platform for the creation of disease models, tissue regeneration, therapeutic screening and drug development. The convergence of engineering and cellular/molecular biology has led to emerging approaches to integrate biologically active components, such as cells, proteins and DNAs into micro-/nanofabricated devices. These bioengineered systems present exciting opportunities to serve as vehicles for biomedical and biopharmaceutical applications.

Bioengineering Trabecular Meshwork Complex for Outflow Physiology and High-throughput Anti-glaucoma Screening

Glaucoma is an age-related disease and a leading cause of irreversible blindness.  Primary open angle glaucoma (POAG) represents 90% of glaucoma cases. POAG is characterized by the presence of an open, normal-appearing anterior chamber angle together with increased intraocular pressure (IOP). IOP is determined by the balance between aqueous humor production and elimination (so called outflow). Human trabecular meshwork (HTM) along with its underlining human Schlemm’s canal (HSC) endothelial cells (so called conventional outflow pathway) controls the majority aqueous humor outflow and determines the IOP, which is the only modifiable risk factor of glaucoma. The current perfusion study is heavily relied on the use of ex vivo anterior segment culture from donors which is expensive, difficulty to prepare and not suitable for high throughput testing. Generation of a functional in vitro model of the conventional outflow pathway that allows further understanding of outflow physiology and high throughput screening is of high significance. To address this need, Dr. Xie and collaborators have invented the Artificial Conventional Outflow System (ACOS) using primary cells and stem cells grown on microfabricated scaffolds that provides a unique in vitro platform for understanding outflow physiology, drug screening of IOP-modulating agents, and therapeutic development for glaucoma.

Control of Embryonic Stem Cell Fate Using Nanoengineered Microenvironments

Pluripotent stem cells have great potential as unlimited cell sources to treat many major human diseases including cardiovascular disease, neurological disorders, diabetes and cancer. Pluripotet stem cell maintenance and differentiation are governed by unique local microenvironment. A key challenge in stem cell research is to develop an in vitro system that accurately recapitulates functions of the in vivo microenvironment. Our goal is to engineer an in vivo-like stem cell microenvironment to control stem cell expansion and differentiation. The integration of 3-D cues, surface chemistry, drug delivery, microfluidics, and nanotechnology will provide a valuable microsystem for better understanding stem cell- microenvironment interaction, efficiently differentiating stem cells, and facilitating stem cell self-assembly into functional organoids. It will not only set a stage for further understanding stem cell fate decision, but also allow us to develop techniques and strategies for disease modeling, drug development, therapeutic screening, tissue repair and regenerative medicine.

Bioengineering Embryonic Microenvironments to Understand and Restrict Breast Cancer Metastasis

Breast cancer is the most prevalent disease among women worldwide. Metastasis is the leading cause of cancer death. The interaction between cancer cells and their microenvironments plays a crucial role in cancer metastasis. Invasive cancer cells have been linked to embryonic stem cells (ESCs) due to certain similar gene signatures and the convergence of tumorigenic and embryonic pathways. However, embryonic signaling molecules are misexpressed in invasive cancer cells and critical regulators of these signaling pathways are missing in a tumor microenvironment. Since embryonic signaling pathways are tightly controlled in ESCs, bioengineered ESC microenvironments have great potential to supply critical signaling molecules and reprogram the abnormal embryonic signaling pathway in tumors. One of our research goals is to bioengineer embryonic microenvironments using 3D hydrogel and to utilize in vitro dynamic embryonic microenvironments to study ESC-metastatic breast cancer cell interactions. This bioengineering approach provides a unique opportunity for better understanding and effectively restricting metastasis.
