Background
Vitamin D has been implicated in the prevention of heart failure. However the underlying
mechanism remains unclear. We hypothesised that these effects may be partially mediated
by cardiac stem/progenitor cells (CPCs). Therefore, we examined the effects of 1,25-dihydroxyvitamin
D3 (1,25D) on cell cycle activity and differentiation of a previously described CPC
population called cardiac colony-forming unit fibroblasts (cCFU-Fs).
Methods
cCFU-Fs were isolated from adult male C57Bl/6 mouse hearts using fluorescence-activated
cell sorting. The effect of 1,25D on cell proliferation and differentiation were was
assessed by colony-forming and fibroblast differentiation assays. Cell cycle was analysed
by flow cytometry. Mice with induced myocardial infarction (MI) were treated with
1,25D or vehicle controls and cardiac function assessed by echocardiography.
Results
1,25D dose-dependently increased expression of vitamin D receptor (Vdr) and reduced large colony formation. Addition of 1,25D to cCFU-Fs slowed cell proliferation,
promoted cell cycle arrest and decreased expression of pro-fibrotic factors during
TGF-β-induced fibroblast differentiation of cCFU-Fs. After MI, 1,25D-treated mice
had less left ventricular wall thinning and significant improvement in left ventricular
systolic function compared to vehicle-treated controls. Although no significant changes
in myocardial fibrotic area and cardiomyocyte size were noted, treatment with 1,25D
significantly inhibited cardiac interstitial cell proliferation after MI.
Conclusions
Vitamin D signalling promotes cardioprotection after myocardial infarction. This may
be through modulation of cCFU-F cell cycle. The role of 1,25D and VDR in regulating
cardiac stem/progenitor cell function therefore warrants further investigation.

- PreviewVitamin D is a lipid-soluble, steroid hormone that takes two major forms: vitamin D2 (ergocalciferol), found in plants and fortified foods, and vitamin D3 (cholecalciferol), which, in humans, is largely derived from conversion of dehydrocholesterol in the skin, although also acquired from various food sources [1]. Vitamin D3 is converted by 25-hydroxylase in the liver to its inactive metabolite, 25-hydoxyvitamin D3 [25(OH)D], which has a long half-life and is the main measurable form in blood. This, in turn, is converted in the kidneys by 1α-hydoxylase to the bioactive metabolite, 1,25 (OH)2 vitamin D3 [1,25(OH)2D].
