In Vitro Immunomodulatory Effects of Equine Adipose Tissue-Derived Mesenchymal Stem Cells Primed with a Cannabidiol-Rich Extract.
Abstract: Cell-based therapy using mesenchymal stem cells (MSCs) shows promise for treating several diseases due to their anti-inflammatory and immunomodulatory properties. To enhance the therapeutic potential of MSCs, in vitro priming strategies have been explored. Cannabidiol (CBD), a non-psychoactive compound derived from cannabis, may influence MSC proliferation, differentiation, and immunomodulatory properties. This study evaluates the immunomodulatory potential of equine adipose tissue-derived MSCs (EqAT-MSCs) primed with a CBD-rich cannabis extract. EqAT-MSCs (P3) were primed with CBD concentrations of 5 µM and 7 µM for 24 h. Morphological analysis, MTT assay, β-galactosidase activity, apoptosis assays, and gene expression of interleukins IL-1β, IL-6, IL-10, interferon-gamma (IFN-γ), and tumor necrosis factor-alpha (TNF-α) were conducted. Additionally, cannabinoid receptor 1 (CB1) and 2 (CB2) expression were evaluated in naïve EqAT-MSCs (P2-P5). The naïve EqAT-MSCs expressed CB1 and CB2 receptors. Priming with 5 µM significantly increased the expression of IL-10, TNF-α, and IFN-γ, while 7 µM decreased IL-1β and IL-6 expression. No significant changes were observed in other cytokines, MTT, β-galactosidase activity, or apoptosis. These findings demonstrate that naïve EqAT-MSCs express CB1 and CB2 receptors and priming with the extract modulates the expression of pro- and anti-inflammatory cytokines, highlighting its potential immunomodulatory role in EqAT-MSC-based therapies.

This research investigates how priming horse fat-derived stem cells with Cannabidiol (CBD), a non-intoxicating compound from cannabis, may enhance their therapeutic potential due to modifying their proliferation, differentiation, and immune regulating properties.
Objective of the Research
- The main objective of this research was to study the immunomodulatory potential of equine adipose tissue-derived mesenchymal stem cells (MSCs) that had been treated with a CBD-rich extract. This was to understand if CBD has the potential to enhance the therapeutic application of these MSCs by changing their properties like proliferation and differentiation.
Research Methodology
- The equine MSCs were treated with CBD concentrations of 5 µM and 7 µM for 24 hours and subsequently subjected to multiple tests including morphological analysis, MTT assay, β-galactosidase activity, apoptosis assays, and gene expression analysis.
- The gene expression of various interleukins (IL-1β, IL-6, IL-10) and other factors like interferon-gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α) were examined.
- The research also looked at the expression of cannabinoid receptors 1 (CB1) and 2 (CB2) in untreated (naïve) equine MSCs.
Research Findings
- The study found that untreated equine MSCs already expressed CB1 and CB2 receptors.
- Treating the cells with 5 µM of CBD significantly increased the expression of IL-10, TNF-α, and IFN-γ. On the other hand, a 7 µM treatment decreased IL-1β and IL-6 expression.
- No significant changes were observed in other cytokines, in the MTT, β-galactosidase activity, or apoptosis.
Implication of the Findings
- The research shows that treating equine MSCs with CBD-rich extract modulates the expression of certain pro- and anti-inflammatory cytokines, indicating that CBD could potentially have an immunomodulatory role in MSC-based therapy.
- This could enhance the therapeutic potential of stem cell therapy in treating various diseases that involve inflammation and immune system activity.
