Congratulations to Dong Yuqing for his review paper published in International Journal of ACS Applied Materials & Interfaces

2018/04/04      view:

Recently, Ph.D. student Dong Yuqing from BEBC has published his first author paper in International Journal of ACS Applied Materials & Interfaces entitled "Engineering Cell Microenvironment using Novel Photo-responsive Hydrogels ". 


Graphical Abstract

In vivo, cells are located in a dynamic, three-dimensional (3D) cell microenvironment, and various biomaterials have been used to engineer 3D cell microenvironments in vitro to study the effects of the cell microenvironment on the regulation of cell fate. However, conventional hydrogels can only mimic the static cell microenvironment without any synchronous regulations. Therefore, novel hydrogels that are capable of responding to specific stimuli (e.g., light, temperature, pH, and magnetic and electrical stimulations) have emerged as versatile platforms to precisely mimic the dynamic native 3D cell microenvironment. Among these novel hydrogels, photo-responsive hydrogels (PRHs) that are capable of changing their physical and chemical properties after exposure to light irradiation enable the dynamic, native cell microenvironment to be mimicked and show great promise in deciphering the unknown mechanisms of the 3D cell microenvironment in regulating cell fate. Several reviews have already summarized the advances of PRHs and focused on specific photosensitive chemical groups and photo-responsive elements or on the reaction categories and mechanism of PRHs. However, a holistic view of novel PRHs that highlights the multiple physical and chemical properties that can be tuned by remote light activation, as well as their applications in engineering a dynamic cell microenvironment for the regulation of cell behaviors in vitro, is still missing and is the focus of this review.

The work is under the guidance of Dr. Min Lin and Dr. Guorui Jin. The co-authors of the paper include Yuan Hong, Hongyuan Zhu, Dr. Dan Bai, Prof. Tian Jian Lu and Prof. Feng Xu.
