Researchers have uncovered a vital link between vitamin B12 and the efficiency of cellular reprogramming, shedding light on a potential breakthrough in tissue regeneration and rejuvenation strategies. The study, focusing on the expression of key reprogramming factors (OCT4, SOX2, KLF4, and MYC), reveals a global depletion of vitamin B12 during the process, suggesting its crucial role in enhancing therapeutic outcomes.

The investigation, conducted in mice, demonstrated that the reprogramming induced by the expression of OCT4, SOX2, KLF4, and MYC (OSKM) led to a significant depletion of vitamin B12. This finding prompted further exploration into the metabolic requirements of this transient reprogramming strategy, offering insights into potential avenues for improving tissue regeneration and rejuvenation therapies.
Remarkably, the researchers found that supplementing with vitamin B12 increased the efficiency of reprogramming, both in mouse models and cultured cells. This observation suggests a cell-intrinsic effect, highlighting the role of vitamin B12 in enhancing the effectiveness of cellular reprogramming techniques.

The study delved into the molecular mechanisms underlying the link between vitamin B12 and cellular reprogramming. It was discovered that vitamin B12 levels influenced the epigenetic mark H3K36me3, a critical factor in preventing aberrant initiation of transcription. This connection between vitamin B12 levels, H3K36 methylation, transcriptional fidelity, and efficient reprogramming provides valuable insights into the intricate processes at play during cellular reprogramming.
Clinical Implications:
Beyond its implications for cellular reprogramming, the study demonstrated that vitamin B12 supplementation accelerated tissue repair in a model of ulcerative colitis. This suggests that the role of vitamin B12 extends beyond cellular reprogramming to influence broader aspects of tissue regeneration and repair, making it a potential target for therapeutic interventions in various clinical scenarios.
