BackgroundAscorbic acid-2-phosphate has been reported to play a role in cell division and to suppress aging of cell. However, post-thawed cell morphology on various concentration of ascorbic acid is still unclear. In this study, we aimed to observe the morphology of post-thawed adipose-derived stem cells (ADSCs) in medium containing L-ascorbic acid-2-phosphate (LAA2P) (50 and 100 µg/mL).MethodsThe cells were isolated from adipose tissue. Isolated cells then cultured and cryopreserved in liquid nitrogen. We detected mRNA expression of type 1 collagen on day 5. Cell seeded in T25 flask using basal medium [Dulbecco's modified Eagle's medium (DMEM) only] as a control group, DMEM with 10% fetal bovine serum (FBS) and antibiotics as DMFA group, while DMFA with ascorbic acid (50 and 100 µg/mL) as ascorbic acid treatment group.ResultsThe results showed that the cells cultured in DMEM only attached until 96 hours of observation while serum groups with or without ascorbic acid supplementation showed the proliferation until 240 hours of observation. The highest spread size of cell was in a serum group without ascorbic acid supplementation and the highest yield of cells showed in a group with 50 µg/mL of ascorbic acid supplementation. Reduced mRNA expression of type 1 collagen which related to aging was showed in cells cultured without ascorbic acid supplementation.ConclusionsThese results showed that ascorbic acid increased the cell division and suppressed the aging processes indicated by normal spread cell in size compared to cell cultured in DMFA without ascorbic acid supplementation.
