Respect : every TMBL member is important and yet consciously sensitive to other members and the collective impacts. Decisions incorporate inputs from all the stakeholders for fairness and transparency.
Professionalism: every TMBL member strives to attain ever higher quality and standard of her/his own work through mutual empowerment, critique and support to each other.
No-walls culture: solutions to real-life problems can never be confined within artificially-created boundaries (organizational, disciplinary, cultural, inter-personal, or mental inertia).
Sheetz, M., and Yu, H. (2018) The Cell as a Machine, Cambridge University Press, ISBN: 9781107052734.
This unique introductory text has been written by a Lasker Award winning cell biologist; and his PhD student who turned into a biomedical engineer who innovates multiple technologies into award winning companies. It is based on the content and to serve as the text for a course, "Cell as a Machine”, offered by leading universities in the USA and Asia. The course started in 2003 as W3150/4150 in Columbia University, and then taught as course 2.799 in Massachusetts Institute of Technology, and MB5101 in National University of Singapore since 2009, which was extended in different years to Penn, Georgia Tech, UIUC, UC Berkeley/San Diego/Irvine/Davis/Merced, City College of New York, Minnesota, Wash U St Louis, Wisconsin, Boston U and Texas A&M in the US, Hong Kong UST and Zhejiang University in Asia.
The text explains cell functions using the engineering principles of robust devices. Adopting a process-based approach to understanding cell and tissue biology, it describes the molecular and mechanical features that enable the cell to be robust in operating its various components, and explores the ways in which molecular modules respond to environmental signals to execute complex functions. The design and operation of a variety of complex functions are covered, including engineering lipid bilayers to provide fluid boundaries and mechanical controls, adjusting cell shape and forces with dynamic filament networks, and DNA packaging for information retrieval and propagation. Numerous problems, case studies and application examples help readers connect theory with practice, and solutions for instructors and videos of lectures accompany the book online. Assuming only basic mathematical knowledge, this is an invaluable resource for graduate and senior undergraduate students taking single-semester courses in cell mechanics, biophysics, mechanobiology, and cell/tissue biology from a fresh perspective.
Uniquely links together the biology, biophysics, and engineering principles underlying cell functions
Avoids complex mathematical treatments, making it accessible to students with only a basic mathematical background

(2025) Cost-effective Production of Meaty Aroma from Porcine Cells for Hybrid Cultivated Meat. Food Chemistry, 1 May 2025; 473: 142946. doi: 10.1016/j.foodchem.2025.142946.
Cultivated meats are typically hybrids of animal cells and plant proteins, but their high production costs limit their scalability. This study explores a cost-effective alternative by hypothesizing that controlling the Maillard and lipid thermal degradation reactions in pure cells can create a meaty aroma that could be extracted from minimal cell quantities. Using spontaneously immortalized porcine myoblasts and fibroblasts adapted to suspension culture with a 1 % serum concentration, we developed a method to isolate flavor precursors via freeze thawing. Thermal reaction conditions were optimized to enhance aroma compound production. Chemical profiling demonstrates that myoblasts produce an aroma profile closer to pork meat than fibroblasts, although serum reduction decreased aroma yield. Sensory analysis supported these findings. Incorporating the optimized aroma extract – derived from just 1.2 % (w/w) cells – into plant proteins resulted in a hybrid cultivated meat with 78.5 % sensory similarity to pork meat, but with a significant 80 % reduction in production costs.

(2025) A risk-based approach can guide safe cell line development and cell banking for scaled-up cultivated meat production. Nature Food, 3 January 2025; 6: 25-30. doi: 10.1038/s43016-024-01085-9.
For commercial viability, cultivated meats require scientifcally informed approaches to identify and manage hazards and risks. Here we discuss food safety in the rapidly developing feld of cultivated meat as it shifts from lab-based to commercial scales. We focus on what science-informed risk mitigation processes can be implemented from neighbouring felds. We case-study pre-market safety assessments from UPSIDE Foods, GOOD Meat and Vow Group using publicly available dossiers. Quality control and safety assurance practices need to be established and standardized for cell lines and food-grade cell banks.
Lou, X., Wang, J., Kwang, L.G., Zhou, H., Ong, F.Y.T., Ng, S., and Yu, H. (2024) Perforated imprinting on high moisture meat analogue confers long range mechanical anisotropy resembling meat cuts.NPJ Science of Food, 20 December 2024; 8: 106. doi: 10.1038/s41538-024-00344-0
Meat cuts, when cooked and masticated, separate into fibrous structures because of the long-range mechanical anisotropy (LMA) exhibited by muscle fascicles, which is not fully recapitulated in alternative proteins produced using molecular alignment technology like high moisture extrusion. We have developed a scalable perforated micro-imprinting technology to greatly enhance LMA in high moisture meat analogue (HMMA). By imprinting 1 mm thick HMMA sheets with perforated patterns (optimized by AI), we observed up to 5 × more anisotropic separation of fibrous structures in a onedimensional pulling LMA analysis, to match the fibrousness of the cooked chicken breast, duck breast, pork loin and beef loin. We stacked and bound imprinted sheets with transglutaminase (TG) to produce imprinted whole-cuts. Controlling fiber separation in the imprinted cuts achieved hardness ranging from 6578 g to 18467 g (2 cm × 2 cm × 1 cm, 50% strain), which matched meats from different species. Imprinted cuts improved meat-like fiber separation over HMMA when masticated, measured by Euclidean distances (0.057 and 0.106 respectively) to animal meat cuts on image features. In sensory evaluation, imprinted cuts improved consumer acceptance by 33.3% and meat-like fibrousness by 20%, by significantly enhancing the HMMA appearance, texture, and mouthfeel.
