The research on nitric Oxide (NO) and stem cells are the focus in recent years. However, seldom do people conclude the function, mechanism and clinical value of NO in various stem cells including embryonic stem cells (ESCs), endothelial progenitor cells (EPCs), mesenchymal stem cells (MSCs) and neural stem cells (NSCs). In the present review, we evaluate the recent studies on NO in different stem cells and display the latest progresses of NO therapy for tumor, cardiovascular, neurologic and immune system diseases by stem cells.

The marked impairment in cerebrovascular endothelial nitric oxide synthase (eNOS) function that develops after ovariectomy may relate to the observation that the abundance of cerebral vascular eNOS and its endogenous inhibitor, caveolin-1, vary in opposite directions with chronic changes in estrogen status. The authors endeavored, therefore, to establish a link between these correlative findings by independently manipulating, in ovariectomized female rats, eNOS and caveolin-1 expression, while monitoring agonist (acetylcholine)-stimulated eNOS functional activity. In the current study, the authors showed that individually neither the up-regulation of eNOS (through simvastatin treatment), nor the down-regulation of caveolin-1 (through antisense oligonucleotide administration) is capable of restoring eNOS function in pial arterioles in vivo in these estrogen-depleted rats. Only when eNOS up-regulation and caveolin-1 down-regulation are combined is activity normalized. These results establish a mechanistic link between the estrogen-associated divergent changes in the abundance of caveolin-1 and eNOS protein and eNOS functional activity in cerebral arterioles.

The Corona virus SARS-CoV2 that causes COVID-19 has effects that until now have not been explained. The widespread damage of SARS-CoV2, the comorbidities in critically ill COVID-19 patients, and the symptoms of post-COVID-19 patients show striking similarities with conditions that are related to depletion of nitric oxide (NO) in the human body. Many of the symptoms of the disease may be caused by acute depletion of NO by the immune system. Patients with the highest COVID-19 burden often have comorbidities that are related to chronic depletion of NO. Post-COVID-19 health problems may be caused by earlier depletion of NO. Successful therapy requires sufficient NO levels. Supplementation with NO will increase immunity, help prevent thrombosis, and improve breathing, kidney functions, blood flow and oxygenation in patients, elderly patients and patients with comorbidities in particular. Furthermore, NO helps to prevent SARS-CoV2 from entering the human cell and to suppress viral RNA production. NO is not easy to supplement. A few SARS patients have been treated with inhaled NO with positive results, but inhaled NO can only deliver small quantities of NO. A new therapy has been developed to more effectively supplement NO. It combines the ingestion of nitrates (as NO donor), N-acetylcysteine and vitamin C (promoting NO metabolism) with electrostimulation of the muscles (to trigger the release of NO). It is expected that this therapy can ease the most serious symptoms of (post) COVID-19, especially for elderly and people with comorbidities. A patent has been applied for.
