Biomimetic hybrid hydrogels have generated broad interest in tissue engineering and regenerative medicine. Hyaluronic acid (HA) gelatin (hydrolyzed collagen) are naturally derived polymers biodegradable under physiological conditions. Moreover, collagen HA major components of the extracellular matrix (ECM) most tissues (e.g., cardiovascular, cartilage, neural). When used as a material, HA-gelatin may enable mimicking ECM native tissues. Although promising biomimetic substrates, their...
To engineer tissue-like structures, cells must organize themselves into three-dimensional (3D) networks that mimic the native tissue microarchitecture. Microfabricated hydrogel substrates provide a potentially useful platform for directing biomimetic architecture in vitro. Here, we present microgrooved methacrylated gelatin hydrogels as suitable to build muscle-like fibrous structures facile and highly reproducible fashion. Microgrooved with two different ridge sizes (50 100 μm) were...
Establishing the 3D microscale organization of cells has numerous practical applications, such as in determining cell fate (e.g., proliferation, migration, differentiation, and apoptosis) making functional tissue constructs. One approach to spatially pattern is by dielectrophoresis (DEP). DEP characteristics that are important for manipulation, high accuracy, speed, scalability, ability handle both adherent non-adherent cells. However, widespread application this method largely restricted...
Cardiac failure is a critical condition that results in life-threatening consequences. Due to limited number of organ donors, tissue engineering has emerged generate functional constructs and provide an alternative mean repair regenerate damaged heart tissues. In this paper, we review the emerging directions associated with cardiac approaches. particular, discuss use hydrogels regeneration hearts. Because their tissue-like biological, chemical mechanical properties, represent potentially...
Due to the increasing demand generate thick and vascularized tissue engineered constructs, novel strategies are currently being developed. An emerging example is generation of oxygen-releasing biomaterials tackle mass transport diffusion limitations within tissue-like constructs. Biomaterials containing oxygen releasing molecules can be fabricated in various forms such as, hybrid thin films, microparticles, or three dimensional (3D) scaffolds. In this perspective, we will summarize reagents...
Microfabrication technology provides a highly versatile platform for engineering hydrogels used in biomedical applications with high-resolution control and injectability. Herein, we present strategy of microfluidics-assisted fabrication photo-cross-linkable gelatin microgels, coupled providing protective silica hydrogel layer on the microgel surface to ultimately generate gelatin-silica core–shell microgels as vitro cell culture injectable tissue constructs. A microfluidic device having...
Development of three dimensional (3D) microenvironments that direct stem cell differentiation into functional types remains a major challenge in the field regenerative medicine.

Hydrogels commonly used in tissue engineering are mechanically soft, thus often display structural weakness. Herein, we introduce a strategy for enhancing the integrity and fracture toughness of cell-laden hydrogels by incorporating three-dimensional (3D) microfabricated scaffold as element. A digital micromirror device projection printing (DMD-PP) system, rapid prototyping technology which employs layer-by-layer stereolithographic approach, was utilized to efficiently fabricate 3D scaffolds...
Oxygen is essential to cell survival and tissue function. Not surprisingly, ischemia resulting from myocardial infarction induces death necrosis. Attempts regenerate with based therapies exacerbate the hypoxic stress by further increasing metabolic burden. In consequence, implanted engineered cardiac tissues suffer hypoxia-induced death.
