Regenerative Medicine
Summary
Regenerative medicine encompasses interdisciplinary strategies to restore or replace damaged cells, tissues and organs by harnessing the body’s own repair mechanisms or by supplying exogenous bioactive materials. It spans cell‐based therapies, tissue engineering, gene modulation and biomaterial scaffolds, all aimed at shifting a chronically catabolic environment back toward an anabolic, reparative state. Viable cell preparations—ranging from mesenchymal stem cells (MSCs) to induced pluripotent stem cell (iPSC) derivatives—may provide structural support, paracrine signalling or direct differentiation. Biomaterials such as hydrogels or extracellular matrix‐derived scaffolds can foster cell homing and integration, while targeted gene or protein delivery can reprogramme local cells. By modulating inflammation, recruiting progenitors, and guiding matrix remodelling, regenerative interventions seek durable functional repair across a spectrum of musculoskeletal, cardiovascular, metabolic and neurodegenerative conditions.
Research from Nature Portfolio
A first‐in‐human trial of allogeneic iPSC‐derived MSCs in steroid‐resistant acute graft‐versus‐host disease demonstrated safety and tolerability over two years, with no ectopic tissue formation or serious adverse events. Intravenous infusion of a standardised MSC product resulted in survival rates exceeding historical controls and established a framework for off-the-shelf cell therapies in immune-mediated disorders.

The graph below shows the total number of articles in regenerative medicine across all publications each year (not limited to Nature Index journals).
Technical terms
Mesenchymal stem cell (MSC): A multipotent stromal cell capable of differentiating into bone, cartilage, adipose and other mesodermal tissues while exerting immunomodulatory and trophic effects.
Induced pluripotent stem cell (iPSC): A somatic cell reprogrammed to pluripotency, able to generate various specialised cell types including MSCs and organoids.
Paracrine signalling: Cell–cell communication via secreted factors that act on nearby cells to regulate repair, inflammation and angiogenesis.
Hydrogel: A hydrated polymer network used as a scaffold for cell delivery and controlled release of growth factors.
Gene correction: Precise replacement of a disease-causing DNA sequence with a normal sequence, typically via homology-directed repair.
Fetal haemoglobin induction: Upregulation of embryonic haemoglobin to compensate for defective adult haemoglobin in haemoglobinopathies.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
