Osteochondral damage from trauma or osteoarthritis is a general joint disease that can lead to an increased social and economic burden in the modern society. The inefficiency of osteochondral defects is mainly due to the absence of suitable tissue-engineered substrates promoting tissue regeneration and replacing damaged areas. The hydrogels are becoming a promising kind of biomaterials for tissue regeneration. The biomimetic hydrogel microenvironment can be tightly controlled by modulating a number of biophysical and biochemical properties, including matrix mechanics, degradation, microstructure, cell adhesion, and intercellular interactions. In particular, advances in stem cell-laden hydrogels have offered new ideas for the cell therapy and osteochondral repair. Herein, the aim of this review is to underpin the importance of stem cell-laden hydrogels on promoting the development of osteochondral regeneration, especially in the field of manipulation of biomimetic microenvironment and utilization growth factors with various delivery methods.

Regenerative medicine is one of the effective approaches for myocardial infarcted (MI) tissue due to the low capacity of heart for regeneration. However, cell therapy with local administration has shown poor cell retention in the targeted area and limited engraftment capacity at the intended location, resulting in inadequate tissue regeneration. The present study involves mesenchymal stem cell-derived exosomes and encapsulated cells in small and injectable calcium alginate microgels by a specialized microfluidic device to decrease inflammation and increase cell retention in the infarcted tissue.

Efficient cryopreservation of stem cells is crucial to fabricating off-the-shelf cell products for tissue engineering and regeneration medicine. However, it remains challenging due to utilization of toxic cryoprotectants for reducing ice-related cryodamages to stem cells during freeze-thaw cycle, stringent post-thaw washing process, and further integration of stem cells with scaffolds to form tissue engineering constructs for downstream applications. Herein, a novel cryopreservation platform of stem cells based on an antifreezing polyvinylpyrrolidone/gellan gum/gelatin (PGG) scaffold together is reported with an L-proline assisted cell pre-dehydration strategy.

Approaches to regenerate vocal fold in glottic insufficiency remains to be a focus for exploration. This is attributed to the applications of cells or biological molecules alone result in fast degradation and inadequate for regeneration. Development of an injectable hydrogel for glottic insufficiency is challenging, as it needs to be non-cytotoxic, elastic yet possess good strength and easy to fabricate.

Stem cell-based therapies are emerging as significant approaches in tissue engineering and regenerative medicine, applicable to both fundamental scientific research and clinical practice. Despite remarkable results in clinical studies, challenges such as poor standardization of graft tissues, limited sources, and reduced functionality have hindered the effectiveness of these therapies. In this review, we summarize the engineering approaches involved in fabricating stem cell assisted patches and the substantial strategies for designing stem cell-laden engineered patches (SCP) to complement the existing stem cell-based therapies.

Enhancing the biocompatibility of biomaterials is a critical aspect of tissue engineering and regenerative medicine. Advances in 3D bioprinting technology, blending natural and synthetic materials for the production of bioink, offer new opportunities to develop highly biocompatible materials that can closely mimic the native tissue environment. In this study, we used pericardial fluid structure (PFS)-based material together with alginate to mimic the extracellular matrix (ECM) and produce a bioink material.
