L-Ascorbic acid 2-phosphate [23313-12-4]

L-ascorbic acid 2-phosphate (2-Phospho-L-ascorbic acid) is a long-acting vitamin C derivative that can stimulate collagen formation and expression^[1]. L-ascorbic acid 2-phosphate (2-Phospho-L-ascorbic acid) can be used as a culture medium supplement for the osteogenic differentiation of human adipose stem cells (hASCs). L-ascorbic acid 2-phosphate increases alkaline phosphatase (ALP) activity and expression of runx2A in hASCs during the osteogenic differentiation^[2][3].

L-Ascorbic acid 2-phosphate (0.1-1.5 mM; 2 to 3 weeks with medium exchange every 2 to 3 days) significantly stimulates cell growth, whereas addition of l-Ascorbic acid (Asc)  achieves only weak growth stimulation. A combination of Asc-2P and bFGF significantly increases cell growth, but supplementation with EGF and/or insulin does not have any additional effect ^[1].
L-Ascorbic acid 2-phosphate (50 µM-250 µM) is needed for the effective osteogenic differentiation of human adipose stem cells (hASCs), and higher concentrations of AsA2-P results in increased runx2 expression and ALP activity. The highest proliferation, ALP activity and runx2 expression is achieved with 150 µM AsA2-P and 10 nM dexamethasone (Dex), and 250 µM AsA2-P and 5 nM Dex^[3].
