The effects of mitochondrial supplementation on litter size and the ovarian reserve. (a) Assessment of litter size (mean ± SEM) over three generations (1st, 2nd and 3rd) of the offspring derived from founders generated through mitochondrial supplementation (Mito 1st – n = 21 litters; Mito 2nd – n = 19 litters; and Mito 3rd – n = 8 litters). Litter sizes were compared to those from colony control mice (n = 93 litters). (b) Assessment of follicle number (mean ± SEM) from three generations of ten week old mice (Mito 1st; Mito 2nd; and Mito 3rd) generated from founders derived through mitochondrial supplementation and compared to colony controls (control). Primordial, Primordial-Primary Transition, Primary, Primary–Secondary Transition, Secondary, Early Antral, and Antral stages were assessed. (c) Heat map of RNA-Seq profiles. Total identified differentially expressed genes (FDR ≤ 0.05, absolute logFC ≥ 1) for third generation MITO supplemented (treatment; n = 4) and control mice (n = 4) were plotted based on the fold changes (log2) of read counts. ‘Expr lvl’ = expression levels. (d) PANTHER Gene Ontology Classification analysis for biological processes. (e) PANTHER Gene Ontology Classification analysis for molecular functions. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.
