Congratulations to Yufei Ma and Min Lin for their paper published in Adv. Mater.

2018/08/01      view:

Recently, Yufei Ma and Min Lin from BEBC have published their first author paper in Advanced Materials entitled "3D Spatiotemporal Mechanical Microenvironment: A Hydrogel-Based Platform for Guiding Stem Cell Fate ".

Engineering 3D spatiotemporal mechanical microenvironments of stem cells in vitro

Stem cells hold great promise for widespread biomedical applications, for which stem cell fate needs to be well tailored. Besides biochemical cues, accumulating evidence has demonstrated that spatiotemporal biophysical cues (especially mechanical cues) imposed by cell microenvironments also critically impact on the stem cell fate. As such, various biomaterials, especially hydrogels due to their tunable physicochemical properties and advanced fabrication approaches, are developed to spatiotemporally manipulate biophysical cues in vitro so as to recapitulate the 3D mechanical microenvironment where stem cells reside in vivo. Here, the main mechanical cues that stem cells experience in their native microenvironment are summarized. Then, recent advances in the design of hydrogel materials with spatiotemporally tunable mechanical properties for engineering 3D the spatiotemporal mechanical microenvironment of stem cells are highlighted. These in vitro engineered spatiotemporal mechanical microenvironments are crucial for guiding stem cell fate and their potential biomedical applications are subsequently discussed. Finally, the challenges and future perspectives are presented.
The work is under the guidance of Professor Feng Xu. The co-authors of this paper includes Guoyou Huang, Yuhui Li, Shuqi Wang, Guiqin Bai, Tian Jian Lu.
