“…Data indicated that ASC Exos can promote M2-type macrophage polarization (CD206 + cells), and suppress CD86 macrophages. Along with these changes, increased α-SMA + and CD31 + vessels were obtained in ischemic muscle after injection of hypoxic and normoxic Exos [ 287 ]. Despite the existence of therapeutic properties, several obstacles limit the application of Exos in the clinical setting [ 261 ].…”

Muscular diseases and injuries are challenging issues in human medicine, resulting in physical disability. The advent of tissue engineering approaches has paved the way for the restoration and regeneration of injured muscle tissues along with available conventional therapies. Despite recent advances in the fabrication, synthesis, and application of hydrogels in terms of muscle tissue, there is a long way to find appropriate hydrogel types in patients with congenital and/or acquired musculoskeletal injuries. Regarding specific muscular tissue microenvironments, the applied hydrogels should provide a suitable platform for the activation of endogenous reparative mechanisms and concurrently deliver transplanting cells and therapeutics into the injured sites. Here, we aimed to highlight recent advances in muscle tissue engineering with a focus on recent strategies related to the regulation of vascularization and immune system response at the site of injury.

The conversion of liquid resin into solid structures upon exposure to light of a specific wavelength is known as photopolymerization. In recent years, photopolymerization‐based 3D printing has gained enormous attention for constructing complex tissue‐specific constructs. Due to the economic and environmental benefits of the biopolymers employed, photo‐curable 3D printing is considered an alternative method for replacing damaged tissues. However, the lack of suitable bio‐based photopolymers, their characterization, effective crosslinking strategies, and optimal printing conditions are hindering the extensive application of 3D printed materials in the global market. This review highlights the present status of various photopolymers, their synthesis, and their optimization parameters for biomedical applications. Moreover, a glimpse of various photopolymerization techniques currently employed for 3D printing is also discussed. Furthermore, various naturally derived nanomaterials reinforced polymerization and their influence on printability and shape fidelity are also reviewed. Finally, the ultimate use of those photopolymerized hydrogel scaffolds in tissue engineering is also discussed. Taken together, it is believed that photopolymerized 3D printing has a great future, whereas conventional 3D printing requires considerable sophistication, and this review can provide readers with a comprehensive approach to developing light‐mediated 3D printing for tissue‐engineering applications.

Photo‐controlled reversible‐deactivation radical polymerization (RDRP) has recently emerged in light‐based 3D printing at macro‐ and micro‐scales, enabling the elaboration of objects with (re‐)configurable surface properties. The authors' previous work exploits nitroxide‐mediated radical photopolymerization (NMP2) in 3D micro‐printing and subsequent surface modification, by employing analkoxyamine‐based photoresist via 3D direct laser writing (DLW). However, this photoresist suffers from its low photosensitivity to wavelengths above 760 nm, limiting its suitability for commercial 3D DLW setups. To tackle these issues, a new strategy—in situ NMP2 based on a photoresist containing acommercial photoinitiator and a photosensitive‐nitroneis proposed. This photoresist is well‐suited for wavelengths commonly used by 3D DLW systems to obtain well‐defined 3D microstructures. Importantly, the in‐situ formation of alkoxyamine during fabrication allows photo‐induced surface modification of microstructures, highlighted by precise and successive surface patterning. Thesurface modification can be conducted at 800 nm or at wavelengths up to 860 nm. Subsequently, the impact of light wavelength and intensity isinvestigated to understand surface modification. The simple preparation of this novel photoresist allows facile adaptation to digital light processing for 3D macro‐printing. This work broadens the scope of photo‐controlled RDRP in 3D printing and greatly facilitates “living” 3D micro‐ and macro‐printing.
