Title: Innovations by Barbara Pui Chan in Tissue Engineering and Cell-Matrix Technology

Introduction

Barbara Pui Chan is a distinguished inventor based in Hong Kong, CN, known for her significant contributions to the field of tissue engineering and regenerative medicine. With a portfolio of eight patents, she has made notable advancements in creating functional complex tissues necessary for medical applications.

Latest Patents

Her latest patents include methods for complex tissue engineering, which present a simple, highly flexible, and scalable platform for producing functional complex tissues with inherent heterogeneity and irregularity. This innovative method involves combining undifferentiated cells, such as pluripotent or multipotent stem cells, with a biomaterial to create multiple undifferentiated or naive subunits. These subunits are then exposed to various cell culture environments, promoting differentiation towards the required lineages for the complex tissue. By combining differentiated subunits with or without the undifferentiated subunits, and culturing them under suitable biological, chemical, and/or physical conditions, she fine-tunes the structural and functional properties of the bioengineered tissue. This process culminates in the creation of a bioengineered tissue graft designed to replace dysfunctional tissues.

Another significant patent involves the development of cell-matrix microspheres, where a method has been established to produce stable microspheres with up to 100% encapsulation efficiency and high cell viability. This method is applicable in scenarios involving cell therapeutics, including microinjection or surgical implantation, and facilitates 3D culture for in vitro expansion without the need for enzyme digestion or mechanical dissociation. The modified droplet generation method provides a simple, scalable solution, particularly useful when dealing with biomaterials of poor shape and mechanical stability.
