Application

2-Phospho-L-ascorbic acid trisodium salt has been used as medium supplement in Dulbecco′s Modified Eagle Medium (DMEM) for adipose-derived stem cells, human mesenchymal stem cells and osteoblast cells.

Biochem/physiol Actions

L-Ascorbic acid 2-phosphate (AA2P) is used in biocatalytic dephosphorylation for electric power generation and electrochemical detection assays. L-Ascorbic acid 2-phosphate may be used in cell differentiation and tissue engineering applications. Asc-2P is used in studies of gene repression, such as the repression of dihydrotestosterone-induced dickkopf-1 expression.

A recently developed protocol, "microtissue assembly" holds great promise to address the issue of limited mass transfer within engineered large tissue replacements (macrotissues), wherein small "building blocks" (microtissues) are prepared and then assembled into macrotissues. Previous studies suggested that aggregation

Recent studies suggested that dihydrotestosterone (DHT)-driven alteration in the autocrine and paracrine factors may be a key to androgen-potentiated balding. Also, we recently claimed that DHT-inducible dickkopf-1 (DKK-1) is one of the key factors involved in the androgen-potentiated balding. Here
