Abstract
The accelerating biodiversity crisis urgently demands innovative approaches that transcend traditional conservation strategies, which are often constrained by genetic bottlenecks and disease risks. Induced pluripotent stem cells (iPSCs) technology emerges as a transformative solution, enabling non-invasive genetic preservation and multi-pathway species recovery. This review synthesizes advances in reprogramming somatic cells from endangered species into iPSCs through integration-free strategies, such as mRNA, Sendai virus, episomal systems, adenoviruses and chemical induction, thereby reducing genomic instability. We highlight breakthroughs in differentiating iPSCs into functional gametes for assisted reproduction and blastoids formation for embryonic reconstruction, circumventing donor oocyte dependency and genetic homogeneity risks. Despite challenges in lineage specification and epigenetic fidelity, combining iPSC biobanking with ecosystem management enables large-scale genetic rescue. By combining these technologies with ethical frameworks and habitat restoration, the plasticity of cells may be transformed into population resilience, potentially redefining biodiversity conservation.
