Customizable patterned membranes for cardiac tissue engineering: A model-assisted design method.

Myocardial infarction can cause irreversible damage to the heart muscle, which can lead to heart failure. The difficulty of the treatment mainly arises from the anisotropic behavior of the myocardium fibrous structure. Patches or cardiac restraint devices appear to be a promising approach to post-infarction treatment.

3D Printing of a Chitosan and Tamarind Gum Ink: a Two-Step Approach.

3D bioprinting stands out as one of the most promising innovations in the field of high technologies for personalized biomedicine, enabling the fabrication of biomaterial-based scaffolds designed to repair, restore, or regenerate tissues and organs in the body. Among the various materials used as inks, hydrogels play a critical role due to their unique characteristics, including excellent biocompatibility, adjustable mechanical properties, and high solvent retention. This versatility makes them ideal for various applications such as biomedical devices, drug delivery, or flexible electronics.

Accelerated innervation of biofabricated skeletal muscle implants containing a neurotrophic factor delivery system.

Introduction: Volumetric muscle loss (VML) is one of the most severe and debilitating conditions in orthopedic and regenerative medicine. Current treatment modalities often fail to restore the normal structure and function of the damaged skeletal muscle. Bioengineered tissue constructs using the patient's own cells have emerged as a promising alternative treatment option, showing positive outcomes in fostering new muscle tissue formation.
