A Cell Press partner journal
See the unseen. Change the unchanged.
The Innovation ¡ª published by Cell Press in partnership with members of the Youth
Innovation Promotion Association (YIPA),a part of the Chinese Academy of
Sciences¡ªis a new broad-scope, open access journal publishing basic and applied
research that has impact for the benefit of society.
On the cover: The sun not only breeds all life, but also brings inexhaustible clean energy to the earth. The development of flexible photovoltaic technology, represented by flexible perovskite solar cells, frees the energy production from the constraints of traditional centralized photovoltaic application scenarios. From spacecraft and curved photovoltaics to wearable devices and IoT sensors, the combination of flexible photovoltaics and advanced technology will realize a more flexible, convenient and imaginative collection and utilization of solar energy, contributing to a more intelligent and sustainable human society.

2D cell-traction force quantification technology


Cells generate traction forces by interacting with the extracellular matrix (ECM) during migration, contraction, invasion, and spreading. Cell-traction forces (CTFs) are extremely small but have enormous biological effects. It has been discovered that CTFs serve a crucial role in regulating proliferation, differentiation, wound healing, morphogenesis, angiogenesis, inflammation, and tumor genesis by working together with biochemical signals to maintain a coherent framework for these processes. For the study of cell biology, it is essential to understand the possible effect of CTFs on the various cellular functions and the amount of traction forces that can be generated by cells in their various states. Currently, CTF quantification approaches are either confined to detecting numerous scattered places on the surface of cells or are severely limited in temporal and spatial resolution, both of which are critical for living cells. Obtaining a highly accurate and dynamic mapping of the force distribution across living cells in real time via a simple mathematical technique remains a significant difficulty. This perspective provides a brief overview of recent landmark advances in the measurement of two-dimensional (2D) CTFs, as well as unique ideas for future improvement.
