AI Article Synopsis

  • Cell therapy involves transplanting human cells to repair damaged tissues and influence disease processes, with many types currently in use for various diseases.
  • Cell-free therapy has recently gained attention as it utilizes secreted factors from cells (like growth factors and cytokines) to promote tissue repair, proving effective without needing the actual cells.
  • This review examines the pros and cons of both cell therapy and cell-free therapy, exploring their roles and potential future coexistence in regenerative medicine.

Article Abstract

Cell therapy involves the transplantation of human cells to replace or repair the damaged tissues and modulate the mechanisms underlying disease initiation and progression in the body. Nowadays, many different types of cell-based therapy are developed and used to treat a variety of diseases. In the past decade, cell-free therapy has emerged as a novel approach in regenerative medicine after the discovery that the transplanted cells exerted their therapeutic effect mainly through the secretion of paracrine factors. More and more evidence showed that stem cell-derived secretome, i.e., growth factors, cytokines, and extracellular vesicles, can repair the injured tissues as effectively as the cells. This finding has spurred a new idea to employ secretome in regenerative medicine. Despite that, will cell-free therapy slowly replace cell therapy in the future? Or are these two modes of treatment still needed to address different diseases and conditions? This review provides an indepth discussion about the values of stem cells and secretome in regenerative medicine. In addition, the safety, efficacy, advantages, and disadvantages of using these two modes of treatment in regenerative medicine are also critically reviewed.

Chitosan-based injectable porous microcarriers with enhanced adipogenic differentiation and angiogenesis for subcutaneous adipose tissue regeneration.

Biomater Adv

January 2025

Key Laboratory of Theoretical Organic Chemistry and Functional Molecule of the Ministry of Education, Hunan Provincial Key Laboratory of Controllable Preparation and Functional Application of Fine Polymers, School of Chemistry and Chemical Engineering, Hunan University of Science and Technology, Xiangtan, PR China. Electronic address:

Chitosan is a promising biomaterial for tissue engineering, but its functionality is limited by a lack of bioactive sites. This study develops chitosan/amniotic membrane microcarriers to enhance vascularization and tissue regeneration for subcutaneous adipose tissue. The incorporation of decellularized amniotic membrane enhances the bioactivities of chitosan in promoting cell differentiation and angiogenesis.

Fate erasure logic of gene networks underlying direct neuronal conversion of somatic cells by microRNAs.

Cell Rep

January 2025

Department of Developmental Biology, Washington University School of Medicine, St. Louis, MO 63110, USA; Center of Regenerative Medicine, Washington University School of Medicine, St. Louis, MO 63110, USA. Electronic address:

Neurogenic microRNAs 9/9 and 124 (miR-9/9-124) drive the direct reprogramming of human fibroblasts into neurons with the initiation of the fate erasure of fibroblasts. However, whether the miR-9/9-124 fate erasure logic extends to the neuronal conversion of other somatic cell types remains unknown. Here, we uncover that miR-9/9-124 induces neuronal conversion of multiple cell types: dura fibroblasts, astrocytes, smooth muscle cells, and pericytes.

Cellular and gene therapy (CGT) products have emerged as a popular approach in regenerative medicine, showing promise in treating various pancreatic and liver diseases in numerous clinical trials. Before these therapies can be tested in human clinical trials, it is essential to evaluate their safety and efficacy in relevant animal models. Such preclinical testing is often required to obtain regulatory approval for investigational new drugs.

Liver organoids have been increasingly adopted as a critical in vitro model to study liver development and diseases. However, the pre-vascularization of liver organoids without affecting liver parenchymal specification remains a long-lasting challenge, which is essential for their application in regenerative medicine. Here, the large-scale formation of pre-vascularized human hepatobiliary organoids (vhHBOs) is presented without affecting liver epithelial specification via a novel strategy, namely nonparenchymal cell grafting (NCG).
