Experimental study utilizing a standardized Balb C mouse model. ⋯ In the acute phases of SCI, Umbilical cord blood-derived mononuclear cells applied directly to Balb C mice lesions demonstrated histological improvement but played a limited role in functional enhancement. The study highlights distinctions in the treatment's efficacy, potentially related to these cells' diverse differentiation capacities and intrinsic properties.

Mitochondrial DNA alterations in precision oncology: Emerging roles in diagnostics and therapeutics.
Mitochondria are dynamic organelles essential for vital cellular functions, including ATP production, apoptosis regulation, and calcium homeostasis. Increasing research has highlighted the significance of mitochondrial DNA (mtDNA) content and alterations in the development and progression of various diseases, including cancer. ⋯ The authors explore the mechanisms by which mtDNA mutations contribute to tumorigenesis and therapy resistance, the impact of heteroplasmy in cancer biology, and the integration of mtDNA-based diagnostics with current therapeutic strategies. Additionally, the authors highlight the experimental tools and models currently used to investigate mtDNA alterations in cancer, including advanced sequencing technologies and animal models.
