This book summarizes the NATO Advanced Research Workshop (ARW) on "Nanoengineered Systems for Regenerative Medicine" that was organized under the auspices of the NATO Security through Science Program. I would like to thank NATO for supporting this workshop via a grant to the co-directors. The objective of ARW was to explore the various facets of regenerative me- cine and to highlight role of the "the nano-length scale" and "nano-scale systems" in defining and controlling cell and tissue environments. The development of novel tissue regenerative strategies require the integration of new insights emerging from studies of cell-matrix interactions, cellular signalling processes, developmental and systems biology, into biomaterials design, via a systems approach. The chapters in the book, written by the leading experts in their respective disciplines, cover a wide spectrum of topics ranging from stem cell biology, developmental biology, ce- matrix interactions, and matrix biology to surface science, materials processing and drug delivery. We hope the contents of the book will provoke the readership into developing regenerative medicine paradigms that combine these facets into cli- cally translatable solutions. This NATO meeting would not have been successful without the timely help of Dr. Ulrike Shastri, Sanjeet Rangarajan and Ms. Sabine Benner, who assisted in the organization and implementation of various elements of this meeting. Thanks are also due Dr. Fausto Pedrazzini and Ms. Alison Trapp at NATO HQ (Brussels, Belgium). The commitment and persistence of Ms.
