Autor: Madhu Sudhan Reddy Gudur, Rameshwar R Rao, Alexis W Peterson, David J Caldwell, Jan P Stegemann, Cheri X Deng

Publikováno v: PLoS ONE, Vol 9, Iss 1, p e85749 (2014)

Non-destructive monitoring of engineered tissues is needed for translation of these products from the lab to the clinic. In this study, non-invasive, high resolution spectral ultrasound imaging (SUSI) was used to monitor the differentiation of MC3T3

Vasculogenesis and angiogenesis in modular collagen–fibrin microtissues

Autor: Rameshwar R. Rao, David J. Caldwell, Ana Y. Rioja, Andrew J. Putnam, Alexis W. Peterson, Jan P. Stegemann

Publikováno v: Biomater. Sci.. 2:1497-1508

The process of new blood vessel formation is critical in tissue development, remodeling and regeneration. Modular tissue engineering approaches have been developed to enable the bottom-up assembly of more complex tissues, including vascular networks.

New Paradigm for Allosteric Regulation of Escherichia coli Aspartate Transcarbamoylase

Autor: Jennifer K Truong, Gregory M. Cockrell, Evan R. Kantrowitz, Wenyue Guo, Alexis W. Peterson, Yunan Zheng

Publikováno v: Biochemistry. 52:8036-8047

For nearly 60 years, the ATP activation and the CTP inhibition of Escherichia coli aspartate transcarbamoylase (ATCase) has been the textbook example of allosteric regulation. We present kinetic data and five X-ray structures determined in the absenc

Winner for outstanding research in the Ph.D. category for the 2013 society for biomaterials meeting and exposition, April 10-13, 2013, Boston, Massachusetts

Autor: Jan P. Stegemann, Rameshwar R. Rao, Alexis W. Peterson

Publikováno v: Journal of Biomedical Materials Research Part A. :1531-1538

Modular tissue engineering applies biomaterials-based approaches to create discrete cell-seeded microenvironments, which can be further assembled into larger constructs for the repair of injured tissues. In the current study, we embedded human bone m

Noninvasive, Quantitative, Spatiotemporal Characterization of Mineralization in Three-Dimensional Collagen Hydrogels Using High-Resolution Spectral Ultrasound Imaging

Autor: Rameshwar R. Rao, Alexis W. Peterson, Madhu Sudhan Reddy Gudur, Jan P. Stegemann, Yi-Sing Hsiao, Cheri X. Deng

Publikováno v: Tissue Engineering Part C: Methods. 18:935-946

As tissue engineering products move toward the clinic, nondestructive methods to monitor their development and ensure quality are needed. In this study, high-resolution spectral ultrasound imaging (SUSI) was used to noninvasively characterize mineral

Dual-phase osteogenic and vasculogenic engineered tissue for bone formation

Autor: Andrew J. Putnam, Jan P. Stegemann, Rameshwar R. Rao, Alexis W. Peterson, David J. Caldwell, Marina L. Vigen

Publikováno v: Tissue engineering. Part A. 21(3-4)

Minimally invasive, injectable bone tissue engineering therapies offer the potential to facilitate orthopedic repair procedures, including in indications where enhanced bone regeneration is needed for complete healing. In this study, we developed a d

Matrix composition regulates three-dimensional network formation by endothelial cells and mesenchymal stem cells in collagen/fibrin materials

Autor: Andrew J. Putnam, Rameshwar R. Rao, Jan P. Stegemann, Alexis W. Peterson, Jacob Ceccarelli

Publikováno v: Angiogenesis. 15(2)

Co-cultures of endothelial cells (EC) and mesenchymal stem cells (MSC) in three-dimensional (3D) protein hydrogels can be used to recapitulate aspects of vasculogenesis in vitro. MSC provide paracrine signals that stimulate EC to form vessel-like str
