Cardiovascular diseases are the major causes of death worldwide. As a part of their ongoing project to construct a tissue engineered cardiac patch to repair damaged heart muscle, Dr. Zhao’s Lab team has recently reviewed contemporary techniques to fabricate heart-specific matrices for cardiac patch engineering. This invited review titled “Constructing biomimetic cardiac tissues: a review of scaffold materials for engineering cardiac patches” was published by Dhavan Sharma (PhD candidate), Morgan Ferguson (MS student), Dr. Timothy J. Kamp (collaborator at University of Wisconsin Madison), and Dr. Feng Zhao in Emergent Materials, Springer. (https://doi.org/10.1007/s42247-019-00046-4)

Engineered tissues are composed of two major components: cells and the extracellular matrix. This review focuses on the latter one, which holds the cells in a 3D space. Recent advances in scaffold fabrication techniques have enabled scientists to a generate heart-specific microenvironment within the engineered tissue constructs. These cardiac-specific scaffolds can be developed using synthetic polymers or native tissues as well as cell sheets. This article will provide readers with a timely review about different fabrication methods that have been employed to develop scaffold materials which ultimately have been used to engineer cardiac patches.


BME Represented at the Gordon Research Conference on the Science of Adhesion

Mount HolyokeBruce Lee (BioMed), Rattapol Pinnaratip, and Md. Saleh Akram Bhuiyan attended the 2019 Gordon Research Conference on the Science of Adhesion in South Hadley, MA.

Lee gave an invited talk entitled “Smart Bioadhesive Inspired by Mussel Adhesive Chemistry.” Pinnaratip gave an oral and a poster presentation entitled “Regulation of Hydrogen Peroxide Concentration from Mussel-inspired Adhesive via Surface-modified Silica Particle Incorporation,” a project directed by Lee. Bhuiyan gave a poster presentation entitled “Direct Deactivation of Catechol-Containing Adhesive using Electrochemistry,” a project directed by Lee.

Sangyoon Han (biomedical engineering) was awarded the Dutch Society of Cell Biology’s Best Poster Award for his work on cell adhesion and migration in inflammation and cancer.

The title of his poster is “Talin-vinculin pre-complex formation dictates maturation of nascent adhesions by accelerated force transmission and vinculin recruitment.”

The 6th ZOO Meeting took place at Blijdorp Zoo, Rotterdam, The Netherlands, May 15-18, 2019.

The ZOO meeting series has become a landmark event in the field of cell adhesion and migration due to unique theme selection, high scientific profile with excellent speakers and limited number of attendees.


Invited Review of Multifunctional Biomedical Adhesives

Multifunctional Biomedical Adhesives passive design active design functionsAdvanced Health Materials published the article “Multifunctional Biomedical Adhesives,” by Bruce Lee, Rupak Rajachar, Rattapol Pinnaratip, Saleh Akram Bhuiyan, and Kaylee Meyers (Biomed). This article is an invited review that described recent advances in designing multifunctional bioadhesives for various biomedical applications.

https://doi.org/10.1002/adhm.201801568

This review discusses strategies for engineering multifunctional biomedical adhesives, which involve two general approaches: passive and active design. Passive adhesives contain inherent structural elements that can carry out additional functions without external influences, whereas active adhesives are designed to respond to environmental changes. These adhesives exhibit new functionality such as antimicrobial properties, self‐healing ability, and the capacity to release drugs.
