TLDR
Vitamin C improved the effect of ASC transplantation on tendonitis by inducing a better stem cell niche by using more vitamin C as a precursor to collagen synthesis, whereas vitamin C was in excess in the combination group because of the added effect ofASCs on tendon healing.Abstract:
Background/aim We hypothesized that combined therapy using adipose-derived stem cells (ASCs) and vitamin C might improve tendon regeneration in tendonitis. To determine combined effects of ASC transplantation with vitamin C, we used senescence marker protein 30 (SMP30)-knockout (KO) mice that cannot biosynthesize vitamin C by themselves. Materials and methods SMP30-KO were divided into four groups: Control, vitamin C, ASCs, and vitamin C plus ASCs. Tendonitis was induced in the achilles tendons via injection of collagenase type I. After 1 week, ASCs were injected into the intratendonal region. After 30 days, all mice were sacrificed and Achilles tendons were isolated. Results Gross and microscopic findings showed mice treated with combination of ASC transplantation and vitamin C showed better tendon regeneration than those in other groups. This combination led to higher serum vitamin C levels than use of vitamin C alone. This indicates that the vitamin C-treated group used more vitamin C as a precursor to collagen synthesis, whereas vitamin C was in excess in the combination group because of the added effect of ASCs on tendon healing. Conclusion This study showed that vitamin C improved the effect of ASC transplantation on tendonitis by inducing a better stem cell niche.read more

TL;DR: It is demonstrated that TGF-β3 is the main inducer of scleraxis, an early expressed tendon marker, while at the same time inhibiting tendon markers normally expressed later, such as decorin, which is induced by BMP-12, b-FGF and AA.

TL;DR: There are potential benefits using a combination of AA and T3 to accelerate tendon healing and the group treated with AA combined with T3 displayed the lowest Svensson, Soslowsky, and Cook total score value of all tissue sections at histopathological examination.

TL;DR: In this article, the authors identify a ration for tendinopathy, the most common disorder affecting tendons, is characterized by chronic disorganization of the tendon matrix, which leads to tendon tear and rupture.

TL;DR: Dose concentration studies of vitamin C in healthy people showed a sigmoidal relationship between oral dose and plasma and tissue vitamin C concentrations, so optimal dosing is critical to intervention studies using vitamin C.
