New molecular aspects in the mechanism of oromaxillofacial cleft prevention by B-vitamins

Clinical and experimental studies show a clear positive effect of B-vitamins in the prevention of oromaxillofacial clefts, especially cleft lip and palate (CL/P). Hereby the local effect of thiamin (B1) in the amniotic fluid is very important for the embryonic facial development as seen in palatal organ models stimulated by topical B-vitamin application (Scheller et al., 2013a). Moreover a low B1 concentration in the serum and amniotic fluid was found in pregnant mice with clefts in their offspring (Scheller et al., 2013b).
